Analysis Questions:
- Compare the systole to diastole
The systole is the pressure when the first tapping or slamming sound is heard through the stethoscope. The diastole is the pressure when the sound disappears. The systole measurement is higher than the diastole measurement. This is because the systole measurement is when the blood pressure first returns while the diastole measurement is when the pulse dies out. Therefore, the systole number will always be higher than the diastole pressure. - What equipment is used to measure heart rate? To measure blood pressure?
To measure heart rate, we used a stethoscope and our index and middle fingers. To measure blood pressure we used a stethoscope and a blood pressure cuff, which is also known as a sphygmomanometer. - Why is using your thumb to measure pulse not ideal?
It is not ideal to use your thumb to measure pulse because there is actually another pulse in your thumb that could mess up the reading when you are the taking your pulse. - In your own words, describe how to use a blood pressure cuff.
First, put the cuff on above the crease of your elbow. Put the drum of the stethoscope on the inside of the elbow, above the crease. Now, pump up the cuff to around 160 mmHg and slowly begin to release the air, and thus the pressure, from the cuff. Listen for the re-entrance of the blood, which will be a loud heartbeat. Make note of the number, and continue to listen to the heartbeat until it fade. Again, take note the number at which the pulse faded away. The first number is the systolic blood pressure while the second is the diastolic blood pressure.
