Final answer:
In infant CPR with one rescuer, the recommended compression-ventilation ratio is 30:2, with chest compressions about 1.5 inches deep at a rate of 100 to 120 per minute, followed by 2 rescue breaths.
Step-by-step explanation:
The question relates to the proper techniques for performing cardiopulmonary resuscitation (CPR) on infants. In both one-rescuer and two-rescuer infant CPR, the recommended compression-ventilation ratio is 30:2. This means you should perform 30 compressions followed by 2 ventilations. Compressions for infant CPR should be made using two fingers for a single rescuer or encircling hands (two thumb-encircling hands technique) if two rescuers are available, and should be about 1.5 inches (about 4 cm) deep at a rate of at least 100 to 120 per minute. After every 30 chest compressions, provide 2 rescue breaths to supply the infant with oxygen.
The resuscitation process is vital because during emergencies, such as cardiac arrest, the heart stops effectively pumping blood, and immediate action is required to maintain blood flow especially to the brain. Current standards emphasize the importance of high-quality chest compressions over artificial respiration, although both elements are important in CPR.
