Diagnostic accuracy of the HUAWEI WATCH D for measuring spinal anesthesia-induced hypotension during elective cesarean section: a diagnostic test.

ABSTRACT:

Background

The newly developed HUAWEI WATCH D (HW) is a wearable smartwatch, primarily designed to measure non-invasive blood pressure (NIBP) at the wrist. Two recent studies have demonstrated that the accuracy of HW is the same as that of mercury sphygmomanometer for measuring BP in adults. This study aimed to validate the accuracy of the HW in hypotension monitoring.

Methods

A total of 118 healthy parturients with singleton pregnancies undergoing elective cesarean section were included. BP was measured three times preoperatively on the left wrist using HW and on the right upper limb using an Omron BP monitor, with the respective mean values recorded as the baseline values in the supine position. After spinal anesthesia, bilateral BP was measured simultaneously by HW and a
