Hypothermia in Cardiac Arrest

Hypothermia in cardiac arrest occurs when the body’s core temperature drops significantly, usually below 95°F (35°C). This can slow down or stop the heart’s electrical activity, leading to cardiac arrest. Cold temperatures reduce the body's metabolic demands and can sometimes protect the brain and other vital organs temporarily. However, severe hypothermia complicates resuscitation efforts, as the body’s response to CPR and defibrillation may be less effective. Special considerations are needed to carefully rewarm the person without causing additional harm. Recognizing hypothermia is crucial in emergency treatment to improve chances of recovery.
