Blood Pressure Monitoring

Non-invasive measurement of systolic and diastolic blood pressure without traditional arm cuffs. Hypertension (≥130/80 mmHg) affects nearly half of US adults and is a leading modifiable risk factor for cardiovascular disease, stroke, and kidney disease. Traditional monitoring requires arm cuff devices, limiting measurement frequency. Wearable BP monitoring enables more frequent tracking to detect white-coat hypertension, masked hypertension, and circadian BP patterns. Technologies include oscillometric wrist cuffs, pulse transit time (PTT) analysis, and PPG waveform analysis. FDA-cleared wearable BP monitors must meet ANSI/AAMI/ISO 81060-2 accuracy standards (±5 mmHg mean error, ±8 mmHg standard deviation). Wearable measurements can be affected by wrist position, cuff placement, and motion; periodic validation against calibrated arm cuff devices is recommended. BP trends over time may be more valuable than individual readings for clinical decision-making.
