Blood Pressure Lab

       When listening through a stethoscope after cutting off blood flow with a sphygmomanometer, the first burst of blood to go through the brachial artery, the artery that the blood is being cut from, creates a high pitched noise that comes from the highest pressure achieved from the contraction. That high pitched noise is the from the systole, and the pressure is called the systolic pressure.

       The diastole is the loud "whoosh" sound that occurs once the heartbeat is becoming more and more normal.  After the diastole, there is silence which shows that that last noise of a beat was the diastole. 

       The equipment use for heart rate is a stethoscope while the tool for measuring blood pressure is a sphygmomanometer. 

       A thumb would not be ideal for taking a pulse because it has its own pulse that can be mistaken for the pulse you are trying to take. 

       When using the sphygmomanometer to take blood pressure start by rolling up the sleeves of the person. Next, have the person lay their arm out straight on a table with their palm facing up and arm level with their heart. deflate the cuff completely by squeezing out the air bag when the nozzle is open. Wrap the deflated cuff around his or her arm tightly and place the stethoscope on top of the brachial artery, and then put in the ear pieces. Now for the action; close the air nozzle and pump air onto the cuff until you hear and heel no pulse and then let out the air small amounts at a time.
