Question

How far down must you compress the sternum when you are giving cardiopulmonary resuscitation to an adult?

1) 1-1 1/2 inches
2) 1 1/2-2 inches
3) 2-2 1/2 inches
4) 2 1/2- 3 inches

Answer 1

In CPR, compress the adult sternum 2-2 1/2 inches deep at a rate of 100 compressions per minute, following proper technique and training.

Step-by-step explanation:

When giving cardiopulmonary resuscitation (CPR) to an adult, the sternum must be compressed 2-2 1/2 inches (5-6 cm) deep. This compression depth is vital to manually pump blood from the heart into the pulmonary and systemic circuits to maintain blood flow, especially to the brain. Proper hand positioning on the sternum between the T4 and T9 vertebrae is crucial to ensure effective chest compressions and to minimize the risk of injury to the patient. CPR should be performed at a rate of 100 compressions per minute, which aligns with the beat of the song "Staying Alive" by the Bee Gees.

It’s important to note that CPR can cause serious injuries if done incorrectly, which is why proper training and certification in CPR techniques are essential for both medical professionals and the general public. High-quality chest compressions are emphasized over artificial respiration, and CPR is continued until the patient regains a heartbeat or is declared dead by a healthcare professional.
