Title: Cardiopulmonary resuscitation Name: University: Date due: Abstract The quality of Cardiopulmonary resuscitation (CPR) is essential in predicting the outcome of a cardiac arrest. The manual CPR is an alternative to mechanical chest-compression. Animal and physiological statistics indicate that the mechanical chest-compression devices are effective than the manual CPR. For that reason, there have been many attempts and much interest in developing the new techniques and equipment to improve the efficiency of CPR. This write up will consider comparison between manual and mechanical CPR, compare their effectiveness, cost, and the survival rate. Besides, studies with specific on perfusion pressure data and physiology comparing original types of mechanical devices and current devices and finally discussion of its use in various age groups and the efficacy of interposed ventilations with the devices (Steen 2002). Introduction In Cardiac resuscitation, the rhythmic application of some force to the body of an invalid is essential in generating blood flow. However, there is no concurrence on this technique of applying force. There is still a need for better external chest compression styles, because statics has it that only 5-15% of those treated with the standard CPR survive cardiac arrest, a) and that it is widely approved that increasing the blood flow that is generated by chest compression improves survival. b) Many chest compressions are ...
