Validation of the PHYSIO-PORT UP ambulatory blood pressure monitor in pregnant women according to the European Society of Hypertension International Protocol revision 2010

Abstract

The present study examines the performance of the ambulatory blood pressure monitor PHYSIO-PORT UP in pregnant and preeclamptic women. The systolic blood pressure (SBP) and the diastolic blood pressure (DBP) of 33 subjects (among them 13 with preeclampsia) were sequentially measured and compared to reference measurements. Those reference measurements were taken by two observers using a mercury sphygmomanometer. Subject recruitment and evaluation of the measurement results were performed according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP 2010). Three readings were recorded per subject under static conditions. The protocol did not include testing under ambulatory conditions. 87/90 (SBP/DBP) of the 99 readings had a difference ≤ 5 mmHg, 96/98 had a difference 98 ≤ 10 mmHg, and 98/99 had a difference ≤ 15 mmHg. 2 out of 3 readings ≤ 5 mmHg was achieved by 31/32 subjects. None of the subjects had less than 1 comparative reading ≤ 5 mmHg. In conclusion, the PHYSIO-PORT UP fulfilled all requirements of the ESH-IP 2010. According to these results, the PHYSIO-PORT UP can be recommended for blood pressure measurement in pregnant women.
