Inflate the cuff. Rapidly squeeze the pump bulb until you no longer hear the sound of your pulse through the stethoscope. Stop once the gauge reads 30 to 40 mmHg above your normal blood pressure.
If you do not know your normal blood pressure, inflate the cuff until the gauge reads between 160 to 180 mmHg.
Deflate the cuff. Open the airflow valve by twisting the screw counterclockwise. Let the cuff deflate gradually.
The gauge should fall 2 mm, or two lines on the gauge, per second.
Systolic blood pressure refers to the force your blood exerts against the artery walls as your heart pumps.This is the blood pressure created when your heart contracts.
Diastolic blood pressure refers to your blood pressure in between heartbeats.
Mistakes can happen while taking your blood pressure, especially if you are not used to doing it. As such, it is important to double-check your findings by taking a second measurement.
