Some people sweat more than others. To determine how much liquid to take during a run or race, you need to know your sweat rate, and that can vary between 1 to 4 quarts per hour. Weigh yourself nude before a timed training run, and then again after. One pound of weight loss equals 1 pint of water loss.
Purpose of CPR. Simply put, the purpose of CPR is to keep oxygen rich blood flowing to the brain and other vital organs if the heart or lungs stop working on their own. The primary function of the heart is to pump blood to the body and the primary function of the lungs is to fill the blood with oxygen. This is what sustains life.
Steps of CPR. CPR (cardiopulmonary resuscitation) is pushing down on a person's chest and breathing into his or her mouth. It is used in emergencies when someone's heart stops beating, or when he or she is not breathing normally (may be gasping for breath) or is not breathing at all.
