Measuring your blood pressure
Blood pressure monitors are available for the upper arm and the wrist. Each has its own pros and cons. They show the higher (systolic) and the lower (diastolic) blood pressure.
Manual blood pressure measurement
Traditional blood pressure monitors consist of a cuff that is placed around the upper arm, a rubber bulb for inflation, and an analog pressure gauge. The rubber bulb and pressure gauge are connected to the cuff by tubes. A stethoscope is also required for the measurement. Once the blood pressure cuff has been correctly placed around the upper arm, it is inflated using the rubber bulb. As the air pressure is released, the resulting Korotkoff sound (turbulent flow sound) of the blood flow can be heard through the stethoscope. From this point onward, blood can flow through the vessel again. The turbulent flow sounds become audible and are recorded as the systolic (upper) blood pressure value. The diastolic (lower) value is defined as the point at which the sounds disappear and the blood can once again flow through the vessel without turbulence-and therefore silently.
There are some more modern blood pressure monitors of the classic type. These have an electronic sensor that replaces the stethoscope. Some of these devices can also measure the pulse rate.
Digital blood pressure monitors
Digital blood pressure monitors take automatic measurements of arterial pressure. They inflate at the push of a button and also deflate automatically. They determine both blood pressure values and the pulse rate. These devices are now available at low cost. There are models for the upper arm and for the wrist. Both methods are considered equivalent, but there are design-related differences. Wrist devices are easier to use, but you must pay close attention to holding your wrist correctly with the measurement point at heart level. With upper-arm devices this position is almost automatic, though you may need to remove clothing from the arm to take a reading.
Blood pressure monitors with a quality seal
A blood pressure monitor sold on the market must comply with the Medical Devices Act. However, this law only states that medical devices must be safe and sufficiently functional. It does not require a specific measurement accuracy. The Deutsche Hochdruckliga awards a seal for devices it has tested: the seal of the Deutsche Hochdruckliga. The testing is carried out by an independent institute unknown to the manufacturer. The test follows a comprehensive protocol with at least 96 participants - more than the Medical Devices Act requires. The test conditions are precisely defined and consistent.
