Life, the technology of manual chest compression is also improved continuous, but is as the application of this technology, and manual chest compression lacks
Fall into and also constantly display, manual cardiopulmonary resuscitation is only provided that 1/3rd of former cerebral blood flow supply, and the blood supply to heart
10-20% (Kern KB, Coronary perfusion pressure during when being only normal
cardiopulmonary resuscitation.Bailliere's Chinical Anaesthesiology.2000；14
(3)：591-609).
Manual cardiopulmonary resuscitation is mainly made up of three steps：Open air flue, artificial respiration and closed cardiac massage.Breast unfaithful intention
The operating procedure of dirty pressing is, the first step：Determine correct closed cardiac massage position, first find arcus costarum lower edge, with handss
Forefinger and middle finger touch upwards to both sides costal margin in the cut channel mark of breastbone junction along rib lower edge, this is put in forefinger and middle finger
On cut channel mark, the palm root of another handss is put in horizontal finger side, then first hands is overlayed on the back of the hand of another handss, two handss
Finger intersects to be buckled, and finger leaves thoracic wall；Second step：Implement pressing, operator leans forward upper body, both shoulders are located above patient chest

Quality (25 ± 3) kg, is randomly divided into full thoracic cavity of the present utility model banding automatic cardiac pressing instrument electro-mechanical system experiment
Group (n=13) and artificial pressing experimental group (n=13).After electric shock induction ventricular fibrillation (quivering in room) causes cardiac arrest 4min respectively
Implement mechanical external chest compression and manual chest compression.
Foundation《The cardio-pulmonary resuscitation of 2010 American Heart Association and emergency cardiovascular care guide》Standard, and with reference to Xanthos etc.
(Xanthos T et a1.Combination pharmacotherapy in the treatment of experimental
Cardiac arrest [J] .Am.J.Emerg.Med.2009,27 (6)：Experimental technique 651-659) carries out CPR.Quiver in room
After 4min, inject 0.02mg/kg epinephrine through right internal jugular vein, give external chest compression simultaneously, continuously press 2min, frequency
For 100 times/min, pressing and relaxation time ratio are 50%：50%, carried out in pressing interval with respiratory balloon trachea conduit
Artificial ventilation, pressing and ventilation ratio are 30：2, each gassing time should continue more than 2s it is ensured that foot exterior feature rises and falls, alternately when ventilating
Carry out；If spontaneous circulation recovers not yet after 2min, with PD1200 defibrillator (ZOLL, the U.S.) with the single-phase ripple defibrillation of 150J.
As defibrillation success electrocardiogram be in straight line or pulseless electrical activity (pulseless electrical activity,
PEA when), monitoring has no effective blood pressure waveform, then repeat above procedure immediately, straight is in recover spontaneous circulation (return of
Spontaneous circulation, ROSC) or CPR to reach 15min invalid and terminate.ROSC standard：Electrocardiogram shows Dou Xingxin
