Wearable Physiological and Blood Pressure Measurements During Activities of Daily Living

The purpose of this data collection was for the validation of a cuffless blood pressure estimation model during activities of daily living. Data were collected on five young healthy individuals (four males, age 28 ± 6.6 yrs) of varied fitness levels, ranging from sedentary to regularly active, and free of cardiovascular and peripheral vascular disease. Arterial blood pressure was continuously measured using finger PPG (Portapres; Finapres Medical Systems, the Netherlands). The Astroskin wearable body metrics vest (Carré Technologies Inc., Canada) was used for electrocardiogram (ECG), photoplethysmogram (PPG), and tri-axial acceleration measurements. The PAT was calculated internally at 256 Hz. An iPhone SE was fixed to the thigh to record the orientation to identify the body posture.
