Population

136 aneroid manometers from 10 University of Michigan Health System sites

Design

Cross-sectional

Authors

Discussion

Supports periodic aneroid calibration checks; leaves open optimal accuracy thresholds for routine clinical reliability.

Are aneroid sphygmomanometers accurate in clinical usage?

Population

136 aneroid manometers from 10 University of Michigan Health System sites

Intervention

Static pressure measurements at nine levels (50, 80, 90, 100, 120, 150, 200 and 250mmHg) using a Universal Biometer DPM-III measuring unit

Outcome

Accuracy of aneroid devices across nine pressure settingssurrogate

Aneroid sphygmomanometers in clinical use are generally accurate, but a yearly calibration program using a +/-2mmHg standard is recommended.

Yarows et al. (2001) studied this question.
