How do you use a sphygmomanometer for blood pressure? |
[Edit] |
What you're asking about is often called a Blood Pressure Cuff.
To use the cuff, wrap it around the arm, just above the elbow and secure it. Some have catches, others use Velcro. Then pump up the pressure in the cuff until you have cut off circulation to the arm. (honest, just hurry)
Next, use a stethoscope to listen for a pulse on the inside of the elbow as you slowly release the pressure in the cuff. As soon as you can hear a pulse, take note of where the pressure needle is. Keep going until the sound of the pulse goes away.
The point at which you can hear the pulse is called the systolic pressure. The point at which the sound goes away is called the diastolic pressure. The numbers are generally reported as "systolic/diastolic", with a relatively healthy BP being 120/80.
