Final answer:
To ensure high-quality CPR, keep your shoulders directly over your hands and bend your elbows during chest compressions. Proper hand placement and compression depth are critical for effective CPR. If someone becomes unresponsive due to choking, immediately begin CPR with chest compressions and call for emergency services.
Step-by-step explanation:
To ensure high-quality CPR (Cardiopulmonary Resuscitation) and high-quality chest compressions, you should keep your shoulders directly over your hands and bend your elbows. The correct answer from the options provided is to keep your shoulders directly over your hands and bend your elbows. When performing CPR, it is crucial to use proper hand placement by placing the heel of your hand on the center of the patient's chest, specifically between the lines at T4 and T9 on the sternum as indicated in Figure 19.2 and Figure 19.3. It is vital to ensure the chest is compressed to a depth of at least 5 cm for adults, with a compression rate of 100 compressions per minute, a rhythm matching the beat of "Staying Alive" by the Bee Gees.
If you are providing care to a patron who started choking on some food and the victim becomes unresponsive, the first thing you should do is call for emergency medical services (if alone, shout for help), then immediately begin CPR, starting with chest compressions. Ensure to check the mouth for any visible blockage when giving compressions and before giving breaths, remove any obstruction if seen. Remember, CPR is performed until the patient has an obvious sign of life or until a trained healthcare professional takes over or declares the person dead. Proper CPR training and recertification are essential to perform this life-saving technique properly and to minimize harm to the patient.
