Conclusions

The measurement of blood pressure is one of the most commonly performed procedures in clinical medicine and should be done carefully.
The main causes of misleading readings should be highlighted in training.
All those who measure blood pressure should be assessed on the practical aspects of the procedure.
Defective or inappropriate equipment must not be used. A phased maintenance programme is essential and inexpensive.
A maintenance programme should be defined for each clinical area where blood pressure measurements are made.
Mercury is a toxic substance. Care must be exercised when handling mercury sphygmomanometers and special precautions taken if mercury spillage occurs.
Automated devices will in time replace mercury sphygmomanometers. Such devices must be subjected to independent validation of accuracy.
Special consideration has to be given to the technique of blood pressure measurement in special groups, such as children, the obese, the elderly and pregnant women.
