Abstract
The present invention discloses a method for monitoring the respiration quantity by the breast impedance. The present invention solves the problems of single respiration monitoring method for patients and difficult evaluation for the respiratory functions of the patients in the clinic work at present. The method for monitoring the respiration quantity by the breast impedance provided by the present invention has the advantages of simple, convenient and easy operation and accurate result, and provides new parameters for the diagnosis of respiration diseases and the evaluation of respiratory functions. The present invention adopts a standard respiratory metering cylinder, an impedance instrument and a computer, and a respiration monitoring device is established. The standard metering cylinder and the impedance instrument collect signals of human body respiration, the computer draws the collected impedance signals into an impedance respiration figure, the corresponding relations between the impedance signals and the impedance respiration figure are established, and therefore, the present invention realizes the monitoring and the real-time correction for the respiratory functions.
Description
Technical field
The present invention relates to a kind of monitoring of respiration method, relate in particular to a kind of method with chest impedance monitoring respiration.
Background technology
At present, in clinical position, usually need to monitor patient's respiratory function, so that timely clear and definite change of illness state proposes corresponding the rescue and therapeutic scheme.Especially for serious infectious respiratory diseases such as picture SARS, bird flus, and the respiratory failure that causes of a variety of causes etc. need be carried out the disease of continuous monitoring to patient's respiratory function.And at present, various monitoring of respiration equipment all can only be monitored patient's respiratory frequency, still do not have the method and apparatus of energy continuous monitoring respiration, breathing rate and respiratory function.In some research, though the chest impedance of application spirogram monitoring respiration is arranged, owing to be subjected to factor affecting such as human body height, body weight, chest measurement and monitoring electrode, monitoring result is difficult to the respiratory function of evaluate patient.
Summary of the invention
Purpose of the present invention is exactly in order to solve the deficiencies in the prior art, and a kind of method with chest impedance monitoring respiration that can effectively monitor in real time respiratory function is provided.
For achieving the above object, the present invention has adopted following technical scheme: a kind of method with chest impedance monitoring respiration, it comprises the steps, a, with the electrodes of impedance instrument in human chest;
B, the standard meter graduated cylinder is connected with computer;
C, human body utilize the monitoring of respiration that carries out of standard meter graduated cylinder variable interval, and the human body impedance variable signal when the breathing that tolerance information and the impedance instrument breathed is simultaneously measured is sent into computer;
D, computer are determined the corresponding relation between tolerance information and impedance signal changing value, set up the benchmark to the monitoring of human body respiration tolerance;
Impedance variation when e, computer utilize the impedance instrument to continue to monitor human body respiration forms the impedance spirogram; According to benchmark, calculate respiration in real time simultaneously.
Electrode adopts the silver electrode of concentric circular among the described step a, is placed in human body both sides chest midaxillary line xiphoid-process horizontal level respectively.
Monitoring criteria the time are set up in the first breath monitoring among the described step c, and each measured value is proofreaied and correct in real time to previous monitoring criteria during each thereafter monitoring of respiration, and human body carries out at least three respiratory movements during each monitoring of respiration.
In the described steps d, according to the impedance variation value of the every 100ml correspondence of tolerance value, set up monitoring criteria, with respiration according to impedance variation value monitoring human.
The present invention adopts respirometer graduated cylinder, impedance instrument and the computer of standard, set up respiration monitoring device,, signals collecting is carried out in the breathing of human body by standard meter graduated cylinder and impedance instrument, computer is drawn the impedance spirogram with the electrical impedance signal of gathering, and sets up corresponding relation between the two; Computer is got first derivative to the data in the impedance spirogram, obtains impedance and breathes differential map, is used to estimate respiratory movement speed; Computer also can be got second dervative to the data in the impedance spirogram, obtains impedance and breathes second dervative figure, reflects respirometric acceleration, is used for the respiratory muscle mechanical analysis and estimates respiratory muscle function.The air velocity of wherein respiratory movement speed reflection human body respiration, its normal range is at 3500-5000ml/s.Breathe acceleration normal range at 0-10000ml/s
2Be to guarantee the accuracy of Monitoring Data, proofread and correct in real time, thereby improved the accuracy of monitoring of respiration breathing benchmark.
Advantage of the present invention is, realized the continuing to monitor of human body respiration transferred to the monitoring of respiration by the monitoring to respiratory frequency, it can better be satisfied the demand, entire method is simple and easy to do, and the result is accurate, can provide new parameter for the diagnosis of respiratory disorder and the evaluation of respiratory function.

Fig. 1 is respiratory impedance figure.
The specific embodiment
Embodiment one:
With one 40 one full year of life, male's asthma patient respiratory detects and is example;
At first the standard meter graduated cylinder is connected with computer, and the impedance instrument also is connected with computer.Monitor initial the time, allow the patient carry out at least three respiratory movements earlier by the standard meter graduated cylinder, each tolerance of breathing is 1.2L, 1.3L, 1.17L, the concentric silver electrode of the instrument of impedance simultaneously is placed on human body both sides chest midaxillary line xiphoid-process horizontal level, the value 1.4,1.54,1.36 of human body impedance is sent into computer during with breathing, computer is set up respective amount with respiratory gas value and impedance variation value according to the impedance variation value of every 100ml correspondence and is concerned 0.116,0.118,0.137, and the benchmark that forms monitoring promptly 0.124.Then, send into computer with the impedance variation value with breathing that the impedance instrument continues, computer then forms the impedance spirogram, as shown in Figure 1, and monitor respiration in real time according to reference value, and be 1.49 o'clock such as its resistance value, respiration is that 1.202L promptly knows the situation of patient respiratory with this.
For further understanding patient's respiratory ventilation flow velocity, available computers is asked first derivative to the related data in the spirogram, breathes differential map thereby obtain impedance, is used to reflect the ventilation flow velocity when breathing.
For understanding patient respiratory flesh function situation, available computers is asked second dervative to spirogram, obtains being used to estimate the second dervative figure that breathes acceleration, so that the function of monitoring respiratory muscle.
For the monitoring accuracy that ensures respiration, need variable interval that monitoring criteria are proofreaied and correct, the timing human body utilizes the standard meter graduated cylinder to breathe, and redefines the impedance variation value of every 100ml correspondence, and sets up the impedance spirogram on new benchmark.
