What ensures proper compression depth during CPR on an adult?

1. Compression depth of about 1-1.5 inches

2. Compression depth of about 2-2.4 inches

3. Compression depth of about 3-4 inches

4. Compression depth as per patients height

The correct answer is: Compression depth of about 2-2.4 inches

The recommended compression depth during cardiopulmonary resuscitation (CPR) for an adult is between 2 and 2.4 inches. This depth is emphasized to ensure effective circulation and to generate adequate blood flow to vital organs during cardiac arrest. A depth of 2 to 2.4 inches strikes the right balance between insufficient compression, which would not effectively circulate blood, and excessive compression, which may cause injury to the patient's ribcage or internal organs. This range is based on extensive research and guidelines established by organizations such as the American Heart Association. Choosing a compression depth based on the patient's height is not a standardized approach; rather, it's critical to adhere to the established depth guidelines to ensure the best chance of survival during a cardiac emergency.
