(Data Table for Heart Rate and Blood Pressure)

In class today, we learned how to measure blood pressure and heart rate. While both require the use of a stethoscope, measuring blood pressure also requires the use of a sphygmomanometer, or blood pressure cuff. To measure blood pressure, one rolls up his or her sleeve past the elbow and extends their arm, palm up. The other person deflates the air bladder of the cuff and wraps it around the first person's arm and places the head of the stethoscope under the edge of the cuff. After, one inflates the cuff until it reaches about 150 mmHg. The measurer should watch the pressure gauge and concentrate on hearing a slight noise that usually appears between 110-140 mmHg, or the the systolic blood pressure. When the noise stops, the number on the pressure gauge is the diastolic blood pressure. While the systolic pressure is the result of the ventricles contracting, diastolic pressure occurs during ventricle relaxation.

On the other hand, measuring heart rate is less complex, where one can measure it by measuring their pulse. However, one should not measure their pulse using his or her thumb because the thumb has its own pulse, so it would be difficult to determine the correct heart rate.
