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.
Start Hands-Only CPR. Hands-Only CPR should not be used for adults whose cardiac arrest is due to drug overdose, near-drowning, or an unwitnessed cardiac arrest. In these cases, do a conventional CPR combination of chest compressions and rescue breathing. Note: For hands-only CPR instructions, watch this video from the American Heart Association. 2. Do Chest Compressions Place the heel of your hand on the center of the person's chest. Place the heel of your other hand on top of your first hand, lacing fingers together.
