In respiratory training, the pressure application to the whole area of the thoracic cavity and the abdominal cavity of a patient is impossible, and the position of the respiratory muscle group of a human body in the thoracic cavity and the abdominal cavity is required to be positioned by the resistance holding in the respiratory process, so that the respiratory training device for respiratory medicine treatment needs to be designed based on the accurate positioning of the pressure application in the respiratory training of the patient resistance.
Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.
Disclosure of Invention
In the prior art, due to the fact that respiratory internal diseases such as pneumonia and the like cause the decrease of respiratory ability of a patient, the influence of respiratory muscle groups on normal work and rest of the patient can cause the problem that the patient generates hypoxia under normal actions or movements, and even if the disease is cured, the subsequent recovery problem caused by the decline of the respiratory muscle groups can bring great trouble to the patient. Clinically, patients with respiratory-related diseases are generally advised to rehabilitate respiratory training after the disease is ameliorated or recovered. Breath training generally selects either simple abdominal breath training or resistance breath training with difficulty based on individual differences.
Resistance breathing training is to increase the contraction pressure of respiratory muscle groups in the breathing process of a patient by holding resistance on the chest or abdominal cavity of the patient when the patient performs abdominal breathing training, and the method is similar to gymnasium weightlifting to increase muscle mass. However, since the respiratory muscle groups perform different functions in different positions of the upper body of the human body and during different respiratory processes, the method of applying pressure to the respiratory muscle groups at different positions while breathing is in different processes has an important influence and effect on promoting the patient to exercise the respiratory muscle groups positively. The accuracy makes the respiratory muscle crowd who participates in the breathing action to the muscle in different positions can obtain better exercise effect, avoids simple pressure to exert the reverse effect that brings simultaneously and just keeps the full pressure face of a position to can even pressure when patient breathes the training and lead to muscle crowd and non-muscle crowd region to receive the pressure and bring uncomfortable feeling for the patient.
Abdominal breathing is a type of breathing that relies mainly on contraction of the abdominal and diaphragm muscles, the key being coordination of the movements of the diaphragm and abdominal muscles in respiratory movements. During inspiration, the abdominal muscles are relaxed, the diaphragm muscles are contracted, the position is moved downwards, and the abdominal wall is expanded; during exhalation, the abdominal muscles contract, the diaphragm muscle relaxes, the abdomen is depressed, and the tidal volume of exhalation is increased. Unlike chest breathing, abdominal breathing causes the patient's chest and abdomen to form a linkage, which expands to form a cavity through abdominal expansion, thereby allowing gases to penetrate into the lung tissue.
In order to overcome the defects in the prior art, the invention provides a respiratory training device for respiratory medicine treatment, which comprises a respiratory muscle group monitoring module for monitoring the motion state of specific respiratory muscles, a training auxiliary module for providing motion assistance for the specific respiratory muscles, and a dispatching center for adjusting the pressure of the specific respiratory muscles, which is provided by the training auxiliary module and is used for resisting muscle force generated in the motion state of specific respiratory muscles, wherein the pressure is used for resisting the contraction or the relaxation of the specific respiratory muscles, which is provided by the training auxiliary module, based on the dynamic change numerical value of the specific respiratory muscles, which is provided by the respiratory muscle group monitoring module, when the specific respiratory muscles, which are monitored by the respiratory muscle group monitoring module, are dynamically changed, the dispatching center controls the training auxiliary module to apply the pressure for resisting the contraction or the relaxation of the specific respiratory muscles to the abdominal region of a trainer. The description of the muscle force of a muscle group referred to in the present invention refers to the magnitude of the force of the muscle acting on the outside during the relaxation or contraction.
Because of the large differences in muscle volume, muscle density, and muscle distribution morphology of the diaphragm, intercostal, and rectus abdominis, accurate pressure application operations in position, size, and directionality are required when applying pressure to different functional areas of the respiratory muscle group.
According to a preferred embodiment, the human body has a wide and numerous distribution of muscle groups involved in the breathing process during breathing, but the muscle groups that play the main role during abdominal breathing are diaphragm, intercostal and rectus abdominis. Specific respiratory muscles refer to the muscle groups involved in and regulating the human abdominal respiratory process, the most important of which are diaphragm, intercostal and rectus abdominis. If other muscle groups have a rhabdolysis disorder or other disorder affecting muscle operation, the abdominal respiration process cannot be directly caused to occur, but when one or more specific respiratory muscles including diaphragm, intercostal muscles and rectus abdominis muscles cannot contract or relax, the human body cannot breathe in an abdominal manner, and even cannot breathe in a serious manner.
According to a preferred embodiment, the training aid module comprises at least three modules for targeting a patientPressure plate areas of diaphragm, intercostal, and rectus abdominis. The three pressure plate areas can apply different pressures to the corresponding muscle groups based on the control of the dispatching center, so that the dispatching center controls the training auxiliary module to apply different pressures for resisting the expansion of the diaphragm, the intercostal and the rectus abdominis based on the muscle strength monitoring values of the diaphragm, the intercostal and the rectus abdominis provided by the respiratory muscle group monitoring module when the patient enters the respiratory process. The area of the pressure plate region can correspond to the area of the diaphragm, intercostal, and rectus abdominis. In particular, the training aid module comprises a first pressure plate acting on the diaphragm. The first pressure plate is capable of acting on the diaphragm of the patient. The first pressure plate is controlled by the dispatch center. The dispatch center acquires the electromyographic signals of the diaphragm. The dispatching center obtains the current muscle strength of the diaphragm based on a formula. The dispatch center controls the first pressure plate to apply a pressure to the diaphragm that is greater than the current muscle strength of the diaphragm. Preferably, the first pressure plate applies a pressure greater than the current muscle strength of the diaphragm by a value F 1 Wherein F is 1 The magnitude of which does not exceed the current muscle strength of the diaphragm.
The training aid module includes a second pressure plate that acts on the intercostal muscles. The second pressure plate is capable of acting on intercostal muscles of the patient. The second pressure plate is controlled by the dispatch center. The dispatching center acquires the myoelectric signals of intercostal muscles. The scheduling center obtains the current muscle strength of intercostal muscles based on a formula.
The dispatch center controls the second pressure plate to apply pressure to the intercostal muscle greater than the current muscle strength of the intercostal muscle. Preferably, the second pressure plate applies a pressure greater than the current myometric magnitude of the intercostal muscle by a value F 2 Wherein F is 2 The magnitude of which does not exceed the current magnitude of the muscular strength of the intercostal muscles.
The training aid module includes a third pressure plate that acts on the rectus abdominis muscle. The third pressure plate is capable of acting on rectus abdominis muscles of the patient. The third pressure plate is controlled by the dispatch center. Myotelecom for obtaining rectus abdominis by dispatching centerNumber (x). The scheduling center obtains the current muscle strength of rectus abdominis based on a formula. The dispatching center controls the third pressure plate to apply pressure to the rectus abdominis muscle which is larger than the current muscle strength of the rectus abdominis muscle. Preferably, the third pressure plate applies a pressure greater than the current myopic muscle strength by a value F 3 Wherein F is 3 The magnitude of the force does not exceed the current magnitude of the rectus abdominis muscle.
Abdominal breathing is a type of breathing that relies mainly on contraction of the abdominal and diaphragm muscles, the key being coordination of the movements of the diaphragm and abdominal muscles in respiratory movements. During inspiration, the abdominal muscles are relaxed, the diaphragm muscles are contracted, the position is moved downwards, and the abdominal wall is raised; during exhalation, the abdominal muscles contract, the diaphragm muscle relaxes, the abdomen is concave, and the tidal volume of exhalation is increased. During respiratory movements, intercostal muscles and auxiliary respiratory muscles are reduced as much as possible to perform work, so that the intercostal muscles and auxiliary respiratory muscles keep relaxed and rest. Therefore, in performing muscle group exercise, rectus abdominis and diaphragm are required as main subjects.
According to a preferred embodiment, the third pressure plate and the first pressure plate applied to the rectus abdominis and diaphragmatis of the patient are capable of applying pressure to the rectus abdominis and diaphragmatis of the patient in a manner that allows the rectus abdominis and diaphragmatis of the patient to be effectively exercised, while the second pressure plate is capable of generating no pressure.
The patients who do not have weak respiratory ability, such as patients suffering from respiratory diseases such as pneumonia, pulmonary alveolar proteinosis, pulmonary lymphatic vessel smooth myomatosis, pulmonary lymphatic vessel cancer, pulmonary thromboembolism, pulmonary arterial hypertension, pulmonary heart disease, primary bronchopulmonary carcinoma, tuberculous pleurisy, parapneumonitis effusion or malignant pleural effusion. Such patients often suffer from poor respiratory ability, short respiratory time, and small amplitude of changes in respiratory muscle group muscle strength. When the patient is subjected to respiratory training of abdominal respiration, the pressure applied to all respiratory muscle groups participating in the abdominal respiration is higher to the patient, so that the device can accurately exercise based on the weak muscle groups of the patient.
According to a preferred embodiment, the dispatch center is capable of applying pressure to one of the patient's diaphragm or rectus abdominis to reduce the patient's burden in respiratory training, wherein the dispatch center is capable of selecting a patient's wealthy muscle group for pressure application based on the patient's historical data to ensure that the wealthy muscle group completes a complete respiratory process while exercising the patient's respiratory muscle group. The patient's historical data is data of the patient's movement state of the respiratory muscle groups of various regions during abdominal breathing. By analyzing the contraction and relaxation lower muscle forces of the respiratory muscle groups in each region during daily abdominal respiration, the maximum upper limit of the muscle force of the respiratory muscle groups in each region of the patient is obtained, and the respiratory muscle groups in each region of the patient are arranged. The history data of the patient in the present invention refers to a dynamic change parameter of the respiratory muscle group in each region when the patient performs abdominal breathing in daily life. The muscle group of the present invention refers to a respiratory muscle group with the smallest difference obtained by comparing the real-time electromyographic signal parameter acquisition and the historical data of the respiratory muscle group in each region, for example, when the muscle force generated by the diaphragm muscle of the patient A in the maximum diastole state in daily life is a, the muscle force generated by the diaphragm muscle of the patient A in the maximum diastole state before and after the illness is a ', the difference between the two is a-a'; when the muscle force generated by intercostal muscles of the patient A in the maximum diastole state in daily life is b ', when the muscle force generated by intercostal muscles of the patient A in the maximum diastole state before and after illness is b ', the difference between the two is b-b ', and when (a-a ') > is (b-b '), the intercostal muscles are the strong muscle groups, and the diaphragm is the weak muscle groups.
According to a preferred embodiment, the dispatching center can change the pressure value of the pressure area of the breathing muscle groups respectively acting on different areas by changing the muscle force of the breathing muscle groups in different areas, so that the exercise effect of the breathing muscle groups in different areas is achieved. Due to the muscle density, upper muscle strength, angle of traction to the thorax and dynamic changes, even with the same respiratory process, different areas of respiratory muscle groups still produce different diastolic forces. For respiratory muscle groups with different diastolic force, in order to avoid ineffective exercise effect of the same pressure for the respiratory muscle groups, pressure plates for the respiratory muscle groups in different areas are arranged, and the pressure plates can be controlled by a dispatching center to generate pressures with different pressure values in different areas.
According to a preferred embodiment, when the respiratory muscle group monitoring module monitors that the increase/decrease of the myoelectric signals of the diaphragm, intercostal and rectus abdominis of the patient becomes decreased/increased, the dispatch center confirms that the patient enters an exhalation state (i.e., that the diaphragm, intercostal and rectus of the patient enter a relaxation state) based on the changes of the myoelectric signals of the diaphragm, intercostal and rectus abdominis of the patient monitored by the respiratory muscle group monitoring module, the dispatch center triggers the application of the training aid module to enter an initial pressure value to the diaphragm, intercostal and rectus abdominis of the patient, respectively. Preferably, the initial pressure values are each 0.01kpa.
According to a preferred embodiment, the pressure exerted by the training aid module acting on the diaphragm, intercostal and rectus abdominis of the patient is gradually increased with an increase in the muscle strength of the diaphragm, intercostal and rectus abdominis of the patient, i.e. the pressure exerted by the training aid module acting on the diaphragm, intercostal and rectus abdominis of the patient is proportional to the change in the muscle strength of the diaphragm, intercostal and rectus abdominis of the patient. The above arrangement enables the magnitude of the pressure acting on the diaphragm, intercostal muscle and rectus abdominis of the patient to be always within the range which does not exceed the bearing range of the diaphragm, intercostal muscle and rectus abdominis of the patient and which produces an exercise effect on the diaphragm, intercostal muscle and rectus abdominis of the patient.
According to a preferred embodiment, the device is capable of monitoring the myoelectric signals of the diaphragm, intercostal and rectus abdominis of the patient only in the first respiratory cycle, in order to confirm that the patient is using the correct abdominal breathing manoeuvre, by checking the participation of the diaphragm as a basis for the patient to perform the correct abdominal breathing manoeuvre. Specifically, the respiratory training device is capable of confirming that the patient is performing a correct abdominal breathing based on a change in the electromyographic signals of the diaphragm muscle monitored by the respiratory muscle group monitoring module, and the dispatch center triggers the training assistance module to enter a standby state in response to the patient performing a correct abdominal breathing.
According to a preferred embodiment, the specific respiratory muscle comprises at least one or several of the group of intercostal muscles, rectus abdominus muscles and diaphragmatis muscles. Preferably, the specific respiratory muscle further comprises one or more of sternocleidomastoid muscle, dorsal muscle group or thoracic muscle group participating in respiratory process.
According to a preferred embodiment, the pressure plate can be arranged in different shapes based on the different respiratory muscle groups for which it is intended.
Since the diaphragm, intercostal and rectus abdominis muscle force of the patient varies widely but precisely during the pressure application, the pressure for the diaphragmatic, intercostal and rectus abdominis muscle in the relaxed state needs to be varied with the variation of the diaphragm, intercostal and rectus abdominis muscle. Monitoring of diaphragmatic, intercostal and rectus electrical signals was obtained and the values of the muscle forces of diaphragmatic, intercostal and rectus along time were obtained by the following formula. The formula is as follows:
F＝α*Z
f is the muscle strength value of the muscle, alpha is the conversion coefficient, and Z is the monitored electromyographic signal value of the diaphragm, intercostal muscle or rectus abdominis muscle.
According to a preferred embodiment, the control center is enabled to adjust the pressure applied by the training aid module to the diaphragm, intercostal and rectus abdominis of the patient based on the muscle strength of the diaphragm, intercostal and rectus abdominis of the patient by monitoring the myoelectric signals of the diaphragm, intercostal and rectus abdominis of the patient in the breathing state and knowing the muscle strength of the diaphragm, intercostal and rectus abdominis of the patient.

Detailed Description
For patients suffering from respiratory diseases, the pressure application in the respiratory training process has more exercise advantages, but due to the influence of the diseases, patients with weakened respiration are easy to have pressure values, pressure areas and even pressure areas excessively supplied when the pressure application is carried out, so that the patients cannot normally complete the respiratory process. For patients, the application of the respiratory muscle groups in all areas can influence the respiratory process of the patients, so that the invention adopts the accurate pressure supply of the respiratory muscle groups and adopts different supply schemes for different respiratory muscle groups, thereby being capable of adjusting the exercise scheme in real time according to the muscle change of the patients in the exercise process and achieving the personalized and accurate exercise mode of the respiratory muscle groups.
In order to overcome the defects in the prior art, the invention provides a respiratory training device for respiratory medicine treatment, which comprises a respiratory muscle group monitoring module for monitoring the motion state of specific respiratory muscles, a training auxiliary module for providing motion assistance for the specific respiratory muscles, and a dispatching center for adjusting the pressure of the specific respiratory muscles, which is provided by the training auxiliary module and is used for resisting muscle force generated in the motion state of specific respiratory muscles, wherein the pressure is used for resisting the contraction or the relaxation of the specific respiratory muscles, which is provided by the training auxiliary module, based on the dynamic change numerical value of the specific respiratory muscles, which is provided by the respiratory muscle group monitoring module, when the specific respiratory muscles, which are monitored by the respiratory muscle group monitoring module, are dynamically changed, the dispatching center controls the training auxiliary module to apply the pressure for resisting the contraction or the relaxation of the specific respiratory muscles to the abdominal region of a trainer. The description of the muscle force of a muscle group referred to in the present invention refers to the magnitude of the force of the muscle acting on the outside during the relaxation or contraction. Because of the large differences in muscle volume, muscle density, and muscle distribution morphology of the diaphragm, intercostal, and rectus abdominis, accurate pressure application operations in position, size, and directionality are required when applying pressure to different functional areas of the respiratory muscle group. Accurate pressure supply is the first step in exercising the respiratory muscle group for patients with respiratory diseases. The respiratory muscle group monitoring module is respectively arranged at each position of the patient in the respiratory process and monitors myoelectric signals at least aiming at diaphragm and rectus abdominis. Through the data supply of the respiratory muscle group monitoring module, the dispatching center can generate the application position of pressure and the magnitude of the applied pressure value, so that a plurality of respiratory muscle groups of a patient participating in the respiratory process can be effectively subjected to compression exercise. For example, as shown in fig. 1, the electromyographic signal monitor monitors the respiratory muscle group of a human body and transmits the monitoring signal to the dispatch center. The dispatch center controls the training aid module (chest and abdomen pressure applying device) to provide pressure to the human body.
According to a preferred embodiment, the training aid module comprises at least three pressure plate areas for the diaphragm, intercostal and rectus abdominis muscles of the patient. The three pressure plate areas can apply different pressures to the corresponding muscle groups based on the control of the dispatching center, so that the dispatching center controls the training auxiliary module to apply different pressures for resisting the expansion of the diaphragm, the intercostal and the rectus abdominis based on the muscle strength monitoring values of the diaphragm, the intercostal and the rectus abdominis provided by the respiratory muscle group monitoring module when the patient enters the respiratory process. The area of the pressure plate region can correspond to the area of the diaphragm, intercostal, and rectus abdominis. In particular, the training aid module comprises a first pressure plate acting on the diaphragm. The first pressure plate is capable of acting on the diaphragm of the patient. The first pressure plate is controlled by the dispatch center. The myoelectric signals of the diaphragm muscle obtained by the dispatching center. The dispatching center obtains the current muscle strength of the diaphragm based on a formula. The dispatch center controls the first pressure plate to apply a pressure to the diaphragm that is greater than the current muscle strength of the diaphragm. Preferably, the first pressure plate applies a pressure greater than the current muscle strength of the diaphragm by a value F 1 Wherein F is 1 The magnitude of which does not exceed the current muscle strength of the diaphragm.
The training aid module includes a second pressure plate that acts on the intercostal muscles. The second pressure plate is capable of acting on intercostal muscles of the patient. The second pressure plate is controlled by the dispatch center. Myoelectric signals of intercostal muscles acquired by the dispatching center. The scheduling center obtains the current muscle strength of intercostal muscles based on a formula. The dispatch center controls the second pressure plate to apply pressure to the intercostal muscle greater than the current muscle strength of the intercostal muscle. Preferably, the second pressure plate applies a pressure greater than the current myometric magnitude of the intercostal muscle by a value F 2 Wherein F is 2 Is not greater than the current muscle strength of intercostal musclesIs small.
The training aid module includes a third pressure plate that acts on the rectus abdominis muscle. The third pressure plate is capable of acting on rectus abdominis muscles of the patient. The third pressure plate is controlled by the dispatch center. Myoelectric signals of rectus abdominis muscle acquired by a dispatching center. The scheduling center obtains the current muscle strength of rectus abdominis based on a formula. The dispatch center controls the third pressure plate to apply pressure to the rectus abdominis muscle that is greater than the current muscle strength of the intercostal muscle. Preferably, the third pressure plate applies a pressure greater than the current myopic muscle strength by a value F 3 Wherein F is 3 The magnitude of the force does not exceed the current magnitude of the rectus abdominis muscle.
The dispatching center can change the pressure value of the pressure area respectively acted on different muscle groups through the muscle force change of the different muscle groups, so that the exercise effect of the different muscle groups is achieved. Due to the muscle density, upper muscle strength, angle of traction to the thorax and dynamic changes, even with the same respiratory process, different areas of respiratory muscle groups still produce different diastolic forces. For respiratory muscle groups with different diastolic force, in order to avoid ineffective exercise effect of the same pressure for the respiratory muscle groups, pressure plates for the respiratory muscle groups in different areas are arranged, and the pressure plates can be controlled by a dispatching center to generate pressures with different pressure values in different areas.
According to a preferred embodiment, the specific respiratory muscle comprises at least one or several of the group of intercostal muscles, rectus abdominus muscles and diaphragmatis muscles. Preferably, the specific respiratory muscle further comprises one or more of sternocleidomastoid muscle, dorsal muscle group or thoracic muscle group participating in respiratory process. For example, partial respiratory training requires only participation of the rectus abdominis and diaphragm, and thus, specific respiratory muscles can refer to rectus abdominis and diaphragm.
Since the diaphragm, intercostal and rectus abdominis muscle force of the patient varies widely but precisely during the pressure application, the pressure for the diaphragmatic, intercostal and rectus abdominis muscle in the relaxed state needs to be varied with the variation of the diaphragm, intercostal and rectus abdominis muscle. Monitoring of diaphragmatic, intercostal and rectus electrical signals was obtained and the values of the muscle forces of diaphragmatic, intercostal and rectus along time were obtained by the following formula. The formula is as follows:
F＝α*Z
f is the muscle strength value of the muscle, alpha is the conversion coefficient, and Z is the monitored electromyographic signal value of the diaphragm, intercostal muscle or rectus abdominis muscle.
For example, the respiratory muscle group monitoring module obtains 0.0366 the myoelectric signal of the patient's diaphragm, and the corresponding F is 0.0366 αkpa based on the above formula.
According to a preferred embodiment, the dispatch center is capable of applying pressure to one of the patient's diaphragm or rectus abdominis to reduce the patient's burden in respiratory training, wherein the dispatch center is capable of selecting a patient's wealthy muscle group for pressure application based on the patient's historical data to ensure that the wealthy muscle group completes a complete respiratory process while exercising the patient's respiratory muscle group. By releasing the patient's muscle groups, the patient in a weakened state can be guaranteed to complete the breathing process, so that other muscle groups can be exercised. For example, the patient is a pneumonia patient with diligent daily exercise, and the diaphragm is a group of tonic muscles and a group of weak muscles because the diaphragm is treated for a longer period of time to be worse than the rectus state (the larger the difference in state is compared with the diaphragm and rectus of a normal person is the worse the position state of the patient). Upon pressure application, the dispatch center applies pressure to the patient's diaphragm.
According to a preferred embodiment, the control center is enabled to adjust the pressure applied by the training aid module to the diaphragm, intercostal and rectus abdominis of the patient based on the muscle strength of the diaphragm, intercostal and rectus abdominis of the patient by monitoring the myoelectric signals of the diaphragm, intercostal and rectus abdominis of the patient in the breathing state and knowing the muscle strength of the diaphragm, intercostal and rectus abdominis of the patient. Preferably, the myoelectric signals of the muscles at the corresponding positions are obtained by collecting surface myoelectric Signals (SEMG) generated by the muscles, thereby obtaining the state of the muscles at that time. Preferably, the diaphragmatic electromyography, diaphragmatic EMG, can be measured by esophageal electrodes, body surface electrodes, and percutaneous transluminal intramuscular electrodes. EMG is composed of different frequencies, mainly 20-350 Hz. The detection method comprises the following steps: esophageal electrode procedures are commonly used. The EMG measurement is typically performed simultaneously with the diaphragmatic muscle pressure measurement. A double-cavity polyethylene plastic bag tube with a plurality of electrodes (usually 7-8 electrodes, i.e. 3-5 pairs of electrodes are combined, and the best signal is taken for analysis) is used. The method of placement was the same as the PDI assay. The signals led out by the electrodes are synchronously output to a recording system and a display after passing through a differential amplifier. The position of the balloon catheter is adjusted as necessary to maximize the signal amplitude of the EMG. The tube is then secured at the nostril. The signal recording system may use a computer data acquisition or tape recorder. The surface electrocardiographic signals are usually recorded simultaneously so as to remove the interference of the electrocardiograph on the EMG during analysis. And selecting the suction phase electromyographic signals for spectrum analysis. Analysis methods of diaphragm EMG results include analysis of activity intensity and analysis of frequency composition (power spectrum). Analysis of activity intensity may employ filtered average signal intensity (FRA) or root of signal squared average (RMS) as an evaluation index. The FRA or RMS at maximum inspiratory effort is taken as the maximum activity intensity reference. The percentage of the actual data to the maximum reference value is used as an indicator of the intensity of diaphragm activity. The ratio of the diaphragmatic pressure to the intensity of diaphragmatic myoelectric activity reflects the efficacy of diaphragmatic activity and measures the intensity of myoelectricity at different frequency ranges. The low frequency component (L: 30-50 Hz) of the EMG spectrum increases and the high frequency component (H: 130-250 Hz) decreases when the diaphragm is fatigued; accordingly, the median frequency spectrum (Fc) decreases.
