Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a cardiopulmonary resuscitation appearance.
Background
Cardiopulmonary resuscitation (CPR) is an important technique for rescuing sudden cardiac arrest, and for many years, scholars at home and abroad are constantly dedicated to research on improving the success rate of CPR, such as: ventricular fibrillation is a main factor of cardiac arrest, and early chest hammering and defibrillation are proposed, wherein the chest hammering is eliminated, but the early defibrillation still is an important measure for improving the CPR success rate. Resuscitation rescue medications, such as high doses of epinephrine and amiodarone (codlong), vasopressin in the european and american CPR guidelines for 2010, were adjusted, but with little effect. A great deal of research has also been done to improve the quality of compressions, such as the adjustment of compression frequency and depth. In order to shorten the compression interruption time as much as possible, a great deal of research has also been conducted on the compression breathing ratio, and the compression breathing ratio is changed many times in the guideline. In order to avoid influence on the compression quality due to insufficient physical strength after long-time compression, an automatic cardio-pulmonary resuscitation instrument and the like are developed. Although these studies have achieved some results, the CPR success rate is not greatly improved, and breakthrough progress is not achieved, the hospital resuscitation success rate is about 15-25%, the pre-hospital resuscitation success rate is maintained at a low level of 5-7%, and the survival rate after resuscitation is good and is only 3.4% without complications.
As is well known, the success rate of CPR depends on the morning and evening of resuscitation, the resuscitation program, which is invariably dependent on the time at which cardiac arrest is found, and the quality of resuscitation, which is well-defined in the resuscitation program guidelines, but the compression and ventilation quality are still currently affected by a variety of factors, such as the skill training of the resuscitator, physical strength, the level of commanders and teams, etc. The quality of compression ventilation is often the key for determining the success of resuscitation, and investigation finds that the standard reaching rate of the compression ventilation is low at present and becomes a restriction factor for the failure of resuscitation success rate. Since the purpose of CPR is to improve hemodynamics, increase blood oxygen partial pressure and decrease CO2 partial pressure, the success rate of CPR also depends on the improvement of hemodynamics and the increase of blood oxygen partial pressure, clearance of CO 2. Compression and artificial ventilation also become the focus and focus of increasing CPR. Currently, the academic community consistently considers that the interruption of compression by artificial respiration during CPR seriously affects the hemodynamics after compression and the success rate of CPR [24], so that the interruption of compression reduction during CPR has been consistently accepted by the academic community, and the flow of CPR has been changed from a (air), b (breaking), c (compressing) to C, A, B. The proportion of breaths is also getting less and less in the past CPR guidelines, from 5: 1 to 15: 2 to 30: 2, and even 30: 1 and simple sustained compressions are under investigation; studies have found that ventilation is insufficient during compression alone, blood oxygen is difficult to increase, CO2 is also difficult to remove, and compression alone without artificial respiration does not improve the success rate of CPR. Therefore, artificial ventilation is an essential link essential for CPR. To date, the ratio of compressions to breaths during CPR has plagued academia.
Studies have been undertaken by scholars on the combination of compression and ventilation, with scholars performing continuous compression + simultaneous positive airway pressure and continuous compression + asynchronous positive airway pressure, and the results of the studies indicate that the success rate of CPR is lower than that of simple continuous compression [28 ]. The former effect is also not ideal because positive pressure ventilation violates normal respiratory physiology, increases intrathoracic pressure and reduces venous return, affecting cardiac output and hemodynamic. The negative pressure in the chest cavity can assist the venous blood to fully flow back, and can generate higher cardiac preload, thereby improving the hemodynamics during CPR, ensuring the perfusion of the coronary artery and the brain, and further determining the resuscitation success rate.
Synchronous High Frequency Jet Ventilation (SHFJV) is a mechanical ventilation technique developed in the middle of the 20 th century with the advantages: the air passage does not need to be sealed, and the influence on the air passage pressure and the intrathoracic pressure is little during ventilation. The disadvantages are that: the noise is high, the airway is easy to dry, and the long-time ventilation is easy to cause the formation of phlegm scab, the storage of CO2 and the like. However, when used for CPR, ventilation for a long time is not necessary, and other disadvantages are not present except for the disadvantage of large noise.
The research gives synchronous high-frequency jet ventilation on the premise of continuous compression, and the latter has little influence on the hemodynamics during compression while ensuring the oxygen and CO2 of a patient to be eliminated, thereby improving the success rate of CPR and the problem of cerebral resuscitation at the later stage. If the test is successful, a novel intelligent automatic cardio-pulmonary resuscitation instrument can be developed, or CPR guidelines can be rewritten.
The standard compression is adopted, the cardiac output is low and can only reach 25-33% of the normal cardiac output, the peak value of the systolic arterial pressure can reach 60-80 mmHg, the diastolic pressure is low, the MAP is less than 40mmHg, and the fatigue cardiac output of a rescuer is further reduced along with the extension of the compression time. Blood flow distribution is abnormal during pressing, and the blood flow is mainly distributed in organs above diaphragm, about 50-90% of cerebral blood flow and about 20-50% of myocardial blood flow, and less than 5% of lower limbs and abdominal organs. 2010 the cardiopulmonary resuscitation guidelines again emphasize the need to perform high quality cardiopulmonary resuscitation, including: a compression rate of at least 100 compressions per minute (rather than "about" 100 compressions per minute); adult compressions of at least 5 cm amplitude; the compression amplitude for infants and children is at least one third of the chest anteroposterior diameter (about 4 cm for infants and about 5 cm for children). However, studies of out-of-hospital and in-hospital cardiac arrest have shown that over 40% of chest compressions do not reach sufficient depth during CPR. The study observed chest compressions at 1 minute of standard CPR, and found that the compressor actually delivered 58 compressions, whereas the only 32 of these actually adequate (compression depth ≧ 3.8cm) compressions. Of the cardiac compressions within two minutes before resuscitation begins, only 19% to 38% of compressions reach the standard depth.
The depth of compression and whether chest wall recoil is sufficient, both of which determine the degree of intrathoracic negative pressure, and the alternating changes in intrathoracic pressure are the kinetics of blood flow during cardiopulmonary resuscitation (thoracic pump theory). However, inadequate chest wall recoil during CPR is very common, especially after fatigue and a fracture in the thorax of the compressor. The fact that the relaxation of compressions and the compression gap the thorax must rebound sufficiently is a point that has long been described and emphasized in the guidelines for cardiopulmonary resuscitation, because of the artificial circulation that works on either the chest pump or heart pump principle, which requires that blood be returned to the thorax by rebounding the thoracic expansion for "ejection" on the next compression. The full rebound of the thorax is therefore of particular importance here.
At present, the process of the thorax rebound, no matter mechanical compression or manual compression, is to utilize the elasticity of the thorax, and when the thorax rebounds after being compressed for a certain depth, the thorax is loosened, and the thorax can automatically recover to the previous position due to the elasticity. However, when the compression is fractured, the elasticity of the thoracic cavity is greatly reduced, which directly reduces the rebound release of the thorax and greatly affects the compression effect. The large amount of rib and sternum fractures can also cause pain after resuscitation, inhibit breathing, cause bronchopneumonia, and cause bleeding after blood vessel and organ puncture (the probability is much less), which should be considered.
Kralj et al recently analyzed 2148 patients with sudden cardiac arrest death between year 2013 in St.vennia 2004. and the data obtained were startling: in men, 86% of patients have one or more CPR-related thoracic skeletal lesions, while in women 91%. Furthermore, there is a certain relationship between sternal and rib fractures: on average, each occurrence of a sternum fracture was accompanied by 4.7 rib fractures.
The most effective treatment for ventricular fibrillation is electrical defibrillation, and the success rate of defibrillation decreases by 7% -10% every 1 minute delay. Ventricular fibrillation can go untreated into more severe arrhythmias such as ventricular arrest or electromechanical detachment within minutes. Therefore, rapid defibrillation is the most critical loop in the survival chain.
