Cross-sectional evaluation reveals high inaccuracy rates in hospital aneroid sphygmomanometers, highlighting the need for routine calibration.

Key Points

Assess the prevalence of physical defects and gauge accuracy in aneroid sphygmomanometers used across hospital and clinical units relative to standard mercury devices.
Inspected 230 aneroid sphygmomanometers for visible structural damage across a university hospital and associated outpatient clinics.
Tested pressure measurement accuracy against a reference mercury manometer across five standard pressure points, defining intolerance as a deviation greater than ±3 mm Hg at two or more points.
Physical defects were widespread, led by misaligned indicator needles outside the zero box, cracked faceplates, and damaged tubing.
Eighty of 230 tested instruments (34.8%) were classified as intolerant, with measurement deviations occurring most frequently at pressure levels of 150 mm Hg or higher.
