Cardiac arrest is diagnosed by the inability to find a pulse in an unresponsive patient. [4] [1] The goal of treatment for cardiac arrest is to rapidly achieve return of spontaneous circulation using a variety of interventions including CPR, defibrillation, and/or cardiac pacing.
According to the CDC, the specific objectives of the project are: [7]. To quantify the incidence and location of cardiac arrest events; To track the performance of each component of the Emergency Medical Services system (e.g., 9-1-1 dispatching and pre-arrival phone instructions, bystander care, first responder, ALS ambulance and definitive care)
According to the American Heart Association, out-of-hospital cardiac arrest can affect more than 300,000 people in the United States each year. [5] Three minutes after the onset of cardiac arrest, a lack of blood flow starts to damage the brain, and 10 minutes after, the chances of survival are low. [6]
Cardiac arrest occurs when the heart stops pumping in a regular rhythm. In this situation, early defibrillation is the key to returning the patient's heart back to a normal rhythm. When a defibrillator is not readily available, a rescuer or bystander should keep the blood flowing by performing chest compressions and rescue breaths at an age ...
Cardioprotection includes all mechanisms and means that contribute to the preservation of the heart by reducing or even preventing myocardial damage. [1] Cardioprotection encompasses several regimens that have shown to preserve function and viability of cardiac muscle cell tissue subjected to ischemic insult or reoxygenation.
High mortality rates due to cardiac injury though, made surgeons to look on how to protect the heart. In 1955 D.G. Melrose suggested ‘’elective cardiac arrest’’, a technique already used for other purposes, in order to protect the heart from ischemia- since cardiac muscle is not working, oxygen demands should be low. In the 1960’s ...
Acidosis (hydrogen cation excess) is an abnormal pH in the body as a result of lactic acidosis which occurs in prolonged hypoxia and in severe infection, diabetic ketoacidosis, kidney failure causing uremia, or ingestion of toxic agents or overdose of pharmacological agents, such as aspirin and other salicylates, ethanol, ethylene glycol and other alcohols, tricyclic antidepressants, isoniazid ...
With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [2]
