Key result
Portable electronic blood pressure devices showed averaged differences of less than 5 mm Hg compared to a Dinamap monitor, providing a reliable means for self-measurement during pregnancy.
Why the study?
Are portable electronic blood pressure devices reliable for self-measurement compared to standard monitors in healthy pregnant women?
Observational (n=31)
Are portable electronic blood pressure devices reliable for self-measurement compared to standard monitors in healthy pregnant women?
Effect estimate: averaged differences < 5 mm Hg
Portable electronic blood pressure monitoring devices provide a reliable and acceptable means for self-measurement of blood pressure during pregnancy.
May support self-monitoring with portable devices in normotensive pregnancy; hypothesis-generating pending outcome validation.
Automatically deflating, battery-operated sphygmomanometers have become commercially available and may enhance the ease and reliability of blood pressure (BP) measurement during pregnancy. In the present study, the reliability of four such devices was compared with a highly accurate Dinamap monitor on 31 healthy pregnant women. Variations between the units were evident. Simultaneous measurements with the Dinamap monitor revealed averaged differences between the systolic, diastolic, and mean arterial pressures to usually be less than 5 mm Hg. These portable electronic devices were also comparable in reliability to a standard, wall-mounted mercury sphygmomanometer (Baumanometer). The readings were not influenced by the person performing the measurement. The most compact electronic unit which was least expensive and most comfortable at peak insufflation was most acceptable to our patients. Portable electronic BP monitoring devices provide a reasonable means for self BP measurement during pregnancy.

Selig et al. (1989) conducted an observational in Healthy pregnancy (n=31). Portable electronic blood pressure devices vs. Dinamap monitor and standard wall-mounted mercury sphygmomanometer was evaluated on Difference in systolic, diastolic, and mean arterial pressures (averaged differences < 5 mm Hg). Portable electronic blood pressure devices showed averaged differences of less than 5 mm Hg compared to a Dinamap monitor, providing a reliable means for self-measurement during pregnancy.
