Final answer:
When performing CPR on an adult with another person, there are key techniques to follow including assessing the situation, starting chest compressions, and providing rescue breaths. Proper hand placement, compression depth, and compression rate are important factors to consider for effective CPR.
Step-by-step explanation:
When performing CPR on an adult with another person, there are a few key techniques to follow:
- First, assess the situation and ensure that the environment is safe for both you and the person in need of CPR. If it is not safe, move the person to a safer location.
- Next, check for responsiveness by tapping the person and asking if they are okay. If they do not respond, shout for help and call emergency services.
- Begin chest compressions by placing the heel of one hand on the center of the person's chest, between the lines at T4 and T9. Place the other hand on top, interlocking your fingers. Keep your elbows straight and position your shoulders directly above your hands.
- Compress the chest at least 2 inches deep and at a rate of around 100 to 120 compressions per minute. You may alternate compressions with the other person every 2 minutes to avoid fatigue.
- After 30 compressions, provide rescue breaths. Tilt the person's head back, lift their chin, and pinch their nose closed. Give 2 breaths that make the person's chest rise. Each breath should last about 1 second.
- Continue this cycle of 30 compressions followed by 2 breaths until help arrives or the person regains consciousness.
