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.
Standard CPR is performed with the person in supine position. Prone CPR or reverse CPR is CPR performed on a person lying on their chest, by turning the head to the side and compressing the back. Due to the head's being turned, the risk of vomiting and complications caused by aspiration pneumonia may be reduced.
