Final answer:
For CPR in adults, pulse checks are typically performed at the wrist or neck, while for infants, the upper arm is used. CPR involves chest compressions and may be followed by AED use. Training is crucial for proper and effective CPR application.
Step-by-step explanation:
To locate a pulse for CPR in adults, rescuers normally check the radial artery in the wrist or the common carotid artery in the neck. In infants, the procedure differs slightly, with the brachial artery in the upper arm being the recommended site to check for a pulse.
Cardiopulmonary resuscitation (CPR) involves chest compressions to maintain blood flow and oxygenation in the event of cardiac arrest. For adults, proper hand placement for compressions is on the sternum, between the lines at T4 and T9. With infants, two fingers are used for compressions just below the nipple line. It's vital to undergo proper training for effective and safe CPR, as incorrect technique can cause serious harm, like broken ribs or damage to internal organs.
Automated external defibrillators (AEDs) are available in many public places and may be used after CPR to help restore normal heart rhythm. AED devices give verbal instructions for use, making them accessible to laypersons.
