Final answer:
A complete CPR cycle for an adult consists of 30 compressions and 2 breaths. High-quality chest compressions are emphasized, and training is essential to perform CPR safely and effectively.
Step-by-step explanation:
On an adult victim, a complete CPR cycle consists of 30 compressions and 2 breaths. CPR, which stands for cardiopulmonary resuscitation, is a critical life-saving technique that can maintain the flow of blood until the heart resumes beating. Proper hand placement is crucial; it should be on the sternum between the lines at T4 and T9. Effective chest compressions should be at least 5 cm deep at a rate of 100 compressions per minute. While the focus is principally on performing high-quality chest compressions, it's essential to remember that CPR training is necessary for applying this technique safely. It's advised that medical personnel and the public get certified and routinely recertified in CPR. The instruction includes practice of the compression technique on mannequins and is offered at various institutions, including schools, hospitals, and organizations like the American Red Cross.
