Final answer:
Chest compressions should not be initiated solely based on a heart rate of less than 60; CPR should start if the heart stops beating. Emphasis is on quality chest compressions, and proper training is vital to prevent injury.
Step-by-step explanation:
The statement 'Chest compressions should start immediately if HR is <60' is false. Cardiopulmonary resuscitation (CPR) should commence if the heart stops beating or in the case of cardiac arrest, not solely based on a specific heart rate reading. Current CPR guidelines emphasize quality chest compressions that are at least 5 cm deep and at a rate of 100 compressions per minute. It is crucial to ensure proper technique, as incorrect hand placement or excessive force can result in serious injuries. Additionally, proper training and recertification in CPR are essential, with courses commonly offered by organizations such as the American Red Cross and hospitals.
