Abstract
Peter Safar. Though mouth-to-mouth resuscitation was described in the Bible (mostly by midwives to resuscitate the newborns), it fell out of practice till it was rediscovered in the 1950s. In early 1960s dr. Kouwenhoven and dr. Knickerbocker discovered the benefit of chest compression to achieve a small amount of artificial circulation. Later in 1960s mouth-to-mouth ventilation and chest compression were combined to form CPR similar to the way it is practiced todaty (Callaway et al, 2005).
Cardiac arrest may occur at the endpoint of many diseases. Examples include acute dysrrhythmia, cardiac pump failure, hypoxia, and sepsis. Often the cause is not Known when treatment is initiated and an approach titrated to real time monitoring is used. When the cause is Known or suspected, theraby can be individualized and directed at the cause. In all cases management has two priorities; rapid restoration of cardiopulmonary functions and minimization of ischemic damage to end organs (Sulivan, 2011).
For some individuals with adequately preserved cardiopulmonary and neurologic systems. Cardiac arrest may be reversed if CPR and definitive care are quickly available and if other systems are also spared, prolonged life may ensue. The short period during which the loss of vital signs may be reversed is often referred to as clinical death. For clinical death to be reversed, ventilation and circulation must be restored before irreversible damage to vital structures occurs. The state of irreversible death is referrred to as biologic death. In difficult circumstances, the single best criterion (both medical and legal) for the biologic death of human individual is brain death. By this criterion we can make decisions as the appropriateness of continuing life-sustaining techniques (Irwin and Rippes, 2010).
