Final answer:
Continue CPR if HR is still under 60 after 1 minute, and ensure it is performed at the correct depth and rate. Proper training and certification are critical to avoid injury while performing CPR.
Step-by-step explanation:
If chest compressions are performed for 1 minute and the heart rate (HR) is still under 60, CPR should continue until the patient regains spontaneous contraction or medical help arrives and takes over. According to current standards, chest compressions should be at least 5 cm deep and at a rate of 100 compressions per minute, which matches the beat of the song "Staying Alive." It is crucial that CPR is performed correctly and safely to minimize harm to the patient. Proper training for performing CPR is essential due to the risks of causing injury such as broken ribs, or in severe cases, driving the xiphoid process into the liver if the hands are placed too low on the sternum during compressions. Therefore, certification and periodic recertification in CPR are highly recommended for medical personnel and the general public.
