Final answer:
The differences in CPR for various age groups involve the depth of chest compressions and the number of compressions before rescue breaths. Adults and children typically receive 30 compressions to two breaths with slightly different compression depths, while infants are given 15 compressions to two breaths at a shallower depth.
Step-by-step explanation:
The actual differences in CPR for an adult, child, and infant are primarily related to the depth of chest compressions and the procedure in emergency situations. For adults and children, it is recommended to give 30 chest compressions before providing two rescue breaths. The depth of compressions should be at least 2 inches (5 cm) for adults and about 2 inches for children above one year old. For infants, compressions should be approximately 1.5 inches deep, and the ratio is often recommended as 15 compressions to two rescue breaths. However, these guidelines can update, and it is important to stay trained and certified for the most current practices in CPR. Additionally, for drowning victims, it's essential to remove the person from the water before attempting CPR.
