[Self measurement of blood pressure: patient education]

Many patients measure their blood pressure without any instruction due to the availability of modern measuring devices. Although the technique can be mastered by most of the patients, some sources of error have to be eliminated. The aim of such an instruction is to explain these sources of error to the patients and to give them opportunity to practise the self measurement under medical supervision. An instruction sheet is handed out as a pamphlet. The patients are also directed to keep a record of all measurements which is periodically controlled by the physician. It is also advisable to reexamine the measuring technique of the patient from time to time and to check the accuracy of the patients measuring device.
