09 cardiac emergencies_and_cpr
This document provides information on cardiac emergencies and performing CPR. It discusses the anatomy and physiology of the circulatory system and heart. Cardiac arrest can be caused by conditions like heart attack, drowning, or drug overdose. CPR involves chest compressions to circulate blood and ventilations to oxygenate blood when someone is unresponsive and not breathing or has no pulse. It is most effective when started immediately and performed correctly with adequate depth and rate of compressions. Two-rescuer CPR minimizes delays in compressions and ventilations to improve the chances of revival.
