Blood pressure measurement at the doctor's office (Korotkoff/Korotkow)

When you visit a doctor, the check-up often starts with measuring your blood pressure. Most doctor's offices still have the classic blood pressure devices known as "sphygmomanometers."

Blood pressure measurement on the upper arm and wrist

For the usual blood pressure measurement, the so-called indirect method is used. A cuff is placed around the upper arm and slowly inflated-either manually or automatically with digital devices. At a certain point, the pressure in the cuff is approximately equal to the pressure in the artery. If the cuff pressure is increased slightly further, the artery in the upper arm is compressed. Blood flow is briefly interrupted at that point. The pulse caused by the heartbeat is no longer audible or palpable. Using a blood pressure manometer, the blood pressure in a medium-sized artery in the arm or leg can be determined in this way.

A stethoscope is used to refine the measurement method. In addition to visual observation, hearing is also used. With a stethoscope the examiner can hear exactly when the cuff pressure compresses the artery. Newer models have a fully automatic electronic measuring device.

The device setup is very similar to the older model, but the readings are shown on a monitor.

1. The cuff is applied.

2. The cuff is inflated until it stops the blood flow.

3. As the air is released, oscillations in the blood flow are recorded.

4. Once the blood flows again without turbulence, the measurement is complete.

By the way:
A study published in September 2023 showed that body position during blood pressure measurement in the doctor's office also matters. Measurements taken with the person sitting on an examination couch, without being able to lean back, place their feet on the floor, or rest their arm, had systolic values 7 mmHg higher and diastolic values 4.5 mmHg higher than when the person sat in a chair with their feet on the floor and their arm supported.
