D) lack mechanisms for metabolic function
Start chest compressions. (Initiate Cardiopulmonary resuscitation.)
Defibrillation stops ventricular fibrillation an resumes normal heart rhythm by delivering electric shock to the chest. Cardiopulmonary resuscitation delays heart damage after patient's collapse. Both are a must within the first few minutes after cardiac arrest to maximize chance of survival.
The body's ability to maintain a relatively constant
internal environment is called homeostasis. This stability can be
challenged by a number of factors, both internal and external, such as extreme heat and extreme cold.
