In mouth-to-mouth resuscitation, the used air exhaled from the rescuer contains a mixture of oxygen and carbon dioxide. While it has a lower oxygen concentration than fresh air, it still contains enough oxygen to be beneficial for the victim, especially in a life-threatening situation where their breathing has stopped. Delivering this air can help maintain some level of oxygenation in the person's lungs and blood, which is crucial until professional medical help arrives or normal breathing is restored.

What is the first step in CPR?

First, you lie the person down on a safe surface. Tilt their head back. Go through ABC ( airway-tilting the head back , Breathing-put your ear over their mouth to hear if they are breathing, Circulation- check their pulse.) If they are not breathing, skip the pulse and go straight to mouth to mouth. Check if they are breathing for two seconds, then give them two breaths. Make sure to breath in and out as you give them the breaths. Then, start CPR pumping. I can't really explain how to align your hands over the internet though, sorry. After pumping 30 times, check if they are breathing. Give them another 2 breaths and keep going until they start breathing or the ambulance arrives. :)


In mouth to mouth resuscitation how would your exhaled breath help the person in receiving aid?

The atmosphere around you contains roughly 20% oxygen. When you inhale, then exhale, you trap some, but even in exhaling after a breath, you're putting out approximately 14% oxygen. While this isn't as good as 20%, it's enough for someone to survive on, and a heck of a lot better than no O2 at all.
