Blood Pressure Management

Differences in consecutive measurements

Blood pressure measurements can easily vary from one moment to the next. In many cases, this is completely normal. Even minor factors such as movement, tension or the method of measurement can alter the result. A brief overview helps to better classify these fluctuations and to understand typical causes.

Why blood pressure measurements sometimes vary

Blood pressure and pulse rate depend on many factors that may also have short-term influence:

  • Physical influences
  • Mental influences
  • Physical movement
  • Muscle tension
  • Speaking
  • Excitement
  • Noise etc.


The type of measurement is also relevant:

  • The cuff being too tight/too loose
  • The cuff not being at heart level
  • The intervals between measurements being too short
  • A lack of visual or auditory patient isolation


Device tolerances also play a part of course. With devices that have a manometer (pressure gauge), the parallax error can also occur.
