Why does the blood pressure determined by the DINAMAP vary?"
A: Some variance is normal and acceptable.

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:
