BLOOD PRESSURE

         Systolic is the top number and is always higher than the bottom number. It measures the pressure in the arteries when the heart beats and the muscle contracts. The diastolic is the bottom number , which is lower of the two numbers. It measures the pressure in the arteries between heartbeats, when the muscle is resting between beats and refilling with blood. Blood pressure can be found using a sethascope and a cuff with a air bulb. To measure heart rate you just find your pulse with your fingers. You can not use your thumb because it also has a pulse. To use the blood pressure cuff you first deflate the air bladder of the cuff and place it around your bicep tightly. Than with your other hand you hold the pump. Than inflate the cuff and watch the pressure. Once you cant hear the pulse anymore you stop pumping. At this point blood pressure is cut off. Than you open the valve and wait for a pshhhh sound.
