How to Take Blood Pressure in Legs
- 1). Use a blood pressure cuff that is an appropriate size to use on a person's leg. Many medical supply stores will sell blood pressure cuffs with a larger circumference to fit a person's thigh.
- 2). Request that the person lay flat on his stomach. You can place a pillow under his head to increase his comfort level.
- 3). Apply the blood pressure cuff at the person's thigh; it does not matter which leg you use. You will also want to place your stethoscope over the person's popliteal artery to listen to the pulse as you take the measurement. The popliteal artery is located behind the knee and is easily accessed while the patient lays flat on his stomach.
- 4). Engage the pump included with the thigh blood pressure cuff. Inflate the cuff rapidly and then loosen the valve inflating the cuff as you listen for a heartbeat. When you hear a sound, the dial gauge will indicate the systolic pressure. Continue to deflate the cuff until the heartbeat stops. This will be the diastolic pressure.
- 5). Adjust the readings of the person's blood pressure when taken in the legs. On average, the systolic reading will be an average of 10 to 20 percent higher than readings taken in the arms. If the blood pressure is lower in the legs than the arms, it is considered an abnormal reading.
