Key result
The IVAC 4200 automated blood pressure device yielded substandard estimates compared to a mercury manometer, with only 59% of systolic and 54% of diastolic readings within 5 mm Hg under optimal conditions.
Why the study?
Does the IVAC 4200 automated blood pressure device accurately measure blood pressure compared to a mercury manometer in stable inpatients?
Cross-Sectional (n=145)
Randomly ordered protocols
Does the IVAC 4200 automated blood pressure device accurately measure blood pressure compared to a mercury manometer in stable inpatients?
The IVAC 4200 automated blood pressure device provides substandard accuracy compared to mercury manometry, which is further worsened by improper cuff selection and patient factors like arrhythmias.

Clinicians should verify IVAC 4200 readings manually; cross-sectional data leave open generalizability to other automated devices.
Shuler et al. (1998) conducted a cross-sectional in Stable inpatients (n=145). IVAC 4200 automated blood pressure device vs. Mercury manometer was evaluated on Accuracy of systolic and diastolic blood pressure readings within 5 mm Hg and 10 mm Hg compared to mercury manometer. The IVAC 4200 automated blood pressure device yielded substandard estimates compared to a mercury manometer, with only 59% of systolic and 54% of diastolic readings within 5 mm Hg under optimal conditions.
