Implication

May underestimate hypertension severity in pre-eclampsia; leaves open need for validated devices in this population.

Key Points

To assess the accuracy of the Omron HEM 705 CP oscillometric blood pressure monitor in pregnant women and those with pre-eclampsia compared to standard sphygmomanometry.
Evaluated 85 pregnant women across a wide range of blood pressures and 43 women with pre-eclampsia across two teaching hospitals.
Tested device accuracy against trained human observers using the British Hypertension Society (BHS) protocol and Association for the Advancement of Medical Instrumentation (AAMI) criteria.
Mean systolic differences (device minus observer) were -0.9 mmHg (SD 10) in normal pregnancy and -2 mmHg (SD 10) in pre-eclampsia.
Mean diastolic differences (Korotkoff phase V) were -1.5 mmHg (SD 10) in pregnancy and -8 mmHg (SD 8) in pre-eclampsia, showing a consistent 8 mmHg diastolic underestimation in pre-eclamptic patients.
Device achieved a BHS grade 'B' in general pregnancy, but only grade 'C' for systolic and grade 'D' for diastolic pressure in pre-eclampsia, failing AAMI criteria across all cohorts.

Does the Omron HEM 705 CP oscillometric device accurately measure blood pressure compared to conventional sphygmomanometry in pregnant women and those with pre-eclampsia?

Population

128 pregnant women, comprising 85 with normal pregnancy and a wide range of blood pressures, and 43 with pre-eclampsia.

Intervention

Blood pressure measurement using the Omron HEM 705 CP oscillometric device.

Comparator

Blood pressure measurement using conventional sphygmomanometry by trained observers.

Outcome

Accuracy of systolic and diastolic blood pressure measurement evaluated according to the British Hypertension Society protocol and Association for the Advancement of Medical Instrumentation (AAMI) criteria.surrogate

The Omron HEM 705 CP oscillometric device is not sufficiently accurate for clinical use in women with pre-eclampsia due to significant underestimation of diastolic blood pressure.

Limitations

The methodology stipulated by the AAMI may not be applicable to a pregnancy population.
