A Remote Blood Pressure Data Collection and Monitoring System for Expectant Mothers

Pre-enclampsia, a condition evidenced by persistent high blood pressure during pregnancy, can lead to the loss of both the mother and child, and often times persists beyond the delivery of the baby. Its early detection through regular blood pressure measurements can inform timely and life saving interventions for both the mother and baby. This study developed a system for remote blood pressure data collection and monitoring incorporating (i) a smartwatch with Photolethysmography (PPG) and Electrocardiogram (ECG) sensors, (ii) a mobile application for receiving the readings through bluetooth and (iii) a mobile application for use by caregivers, namely; ante natal clinic nurses, community health extension workers, community health workers and next of kin, to monitor the blood pressure readings for mothers assigned to them. The system demonstrates significant potential in the early detection of pre-eclampsia, which will in turn inform timely interventions to prevent fatal complications for both mother and baby.
