Clinical accuracy of a low cost portable blood pressure device in pregnancy and pre-eclampsia: the Nissei DS-400.

This study evaluated the accuracy of the Nissei DS-400, a low cost blood pressure (BP) device, in pregnancy according to the British Hypertension Society protocol. Forty-five pregnant women (15 with pre-eclampsia), were recruited from a large teaching hospital. Nine sequential same-arm BP measurements were taken from each woman by trained observers, alternating between mercury sphygmomanometry and the device. The Nissei DS-400 achieved the highest accuracy grade (A/A) in all subjects (n = 45) and in pregnancy alone (n = 30). The mean difference ± standard deviation between the standard and the device in pregnancy were -1.0 ± 5.1 mmHg and -1.1 ± 5.0 mmHg for systolic and diastolic BP, respectively, and -2.6 ± 5.9 mmHg and -3.4 ± 5.8 mmHg in all subjects. The Nissei-DS 400 can be recommended for clinical use in pregnancy and has potential as a good screening tool for pre-eclampsia in low resource settings.
