Which conditions should be standardized for blood pressure measurement?
- Training and certification to minimize observer biases
- Equipment factors such as use of an appropriate cuff bladder size
- Mercury manometer x oscillometric devices
- Technique factors such as recording both the fourth and fifth Korotkoff sounds
- Multiple measurements are vital in estimating a child's blood pressure, and the number of visits, days or weeks apart, is at least as important as the number of measurements per visit
- Minimizing activities before and during the reading
- Environmental factors such as accounting for the time of day and ambient temperature
