The simple answer is that snakes shed their skin because they are just like all other animals. All animals shed their skin â even you! In mammals, especially humans, this is an ongoing process that's rarely noticed. Skin shedding in reptiles is different. Instead of an ongoing process, reptiles shed skin periodically.
According to the International Liaison Committee on Resuscitation guidelines, CPR involves chest compressions at least 5 cm (2 in) deep and at a rate of at least 100 per minute in an effort to create artificial circulation by manually pumping blood through the heart and thus the body.
Repeat the cycle of 30 chest compressions. If you're also doing rescue breaths, keep doing a cycle of 30 chest compressions, and then 2 rescue breaths; repeat the 30 compressions and 2 more breaths. You should do CPR for 2 minutes (5 cycles of compressions to breaths) before spend time checking for signs of life.
