Blood Pressure Issues
Q: Monitor's BP determinations vary.
“I connected the Tester to my Critikon DINAMAP monitor and used the preset
blood pressure of 120/80 (93) with a pulse rate of 80 beats per minute. I
performed three blood pressure determinations with the following results:
Trial # Systolic Mean Diastolic Pulse Rate
1 123 97 82 79
2 126 93 81 81
3 123 97 83 78
Why does the blood pressure determined by the DINAMAP vary?”
A: Some variance is normal and acceptable.
The Tester generates a very repeatable simulation. For this simulation, an ideal
NIBP monitor would show a variation of less than 2 mmHg from one
simulation to the next. Most of the variation seen here originates in the
DINAMAP. This is normal and acceptable.
Section 3.4.3 of the ANSI Standard for Electronic or Automated
Sphygmomanometers specifies the required efficacy of the blood pressure
determination:
