The Microlife WatchBP Home automated blood pressure device was assessed for accuracy in pregnant women of medium (<32 cm) and large (≥32 cm) arm circumference.
The British Hypertension Society validation protocol was modified for the purpose of this study to include women with arm circumference of less than 32 cm (N=51) and greater than or equal to 32 cm (N=46) as two separate arms.
The device achieved an overall A/A grade for medium arm circumference and B/A grade for large arm circumference. The mean±SD device-observer difference was 1.7±6.2 and -0.4±4.4 for systolic and diastolic blood pressure, respectively, for medium arm circumference and 3.0±8.5 and 1.5±5.1, respectively, for large arm circumference. When all women with pre-eclampsia from both groups were pooled (N=23), the device achieved an overall grade of A/A with mean differences of 2.1±7.2 for systolic blood pressure and 1.0±5.6 for diastolic blood pressure.
The Microlife WatchBP Home automated blood pressure device can be recommended for use in pregnant women of all gestations, including those with pre-eclampsia. However, caution is needed for women with large arm circumferences.
评估Microlife WatchBP Home自动血压测量设备在臂围中等（<32厘米）和大（≥32厘米）的孕妇中的准确性。
为该研究目的，对英国高血压学会的验证方案进行了修改，将臂围小于32厘米（N = 51）和大于或等于32厘米（N = 46）的女性作为两个独立的组。
该设备在中等臂围组总体获得A/A等级，在大臂围组获得B/A等级。对于中等臂围，收缩压和舒张压的设备与观察者平均差异分别为1.7±6.2和-0.4±4.4；对于大臂围，分别为3.0±8.5和1.5±5.1。当将两组中所有先兆子痫女性合并（N = 23）时，该设备总体获得A/A等级，收缩压平均差异为2.1±7.2，舒张压平均差异为1.0±5.6。
Microlife WatchBP Home自动血压测量设备可推荐用于所有孕周的孕妇，包括先兆子痫孕妇。然而，对于大臂围女性需要谨慎使用。
