Should you commence CPR on a patient with hypothermia who has no pulse?

Should you commence CPR on a patient with hypothermia who has no pulse?

• A. Yes, there is evidence that CPR, when correctly done, will increase blood flow to critical parts of the body.
• B. No, CPR is not indicated in hypothermia.
• C. Only provide rescue breaths until warmth returns.
• D. Defibrillation is required before CPR.

Answer: (A)

Starting CPR promptly is the best approach because chest compressions and rescue breaths improve blood flow to the brain, heart, and other vital organs even when the patient is hypothermic. Hypothermia lowers the body's metabolic demands and can prolong survival, but it does not remove the need to circulate oxygen and nutrients. High-quality CPR maintains perfusion while you pursue warming and other supportive care, giving the patient a better chance of return of spontaneous circulation. It’s not correct to wait only for warmth or to skip compressions in favor of breaths, because without chest pumps the circulation to vital organs drops dramatically. Defibrillation, if indicated by a shockable rhythm, can be attempted, but it does not replace the need for CPR first—especially in hypothermia where the rhythm and tissue perfusion are the guiding factors until warming improves the situation.
