How Samsung Watches Measure Blood Pressure

Samsung watches that support blood pressure measurement use a combination of optical sensors and advanced algorithms to estimate blood pressure non-invasively. Unlike traditional blood pressure cuffs that physically compress the artery, Samsung employs photoplethysmography (PPG) sensors, which use light to detect blood volume changes in the wrist. These sensors work in conjunction with pulse wave analysis to estimate systolic and diastolic pressures.

Before using the blood pressure feature, users must perform a calibration process with a traditional cuff-based blood pressure monitor. This process establishes a baseline correlation between the user’s actual blood pressure and the optical sensor readings. Once calibrated, the watch uses the sensor data and proprietary algorithms to provide continuous or on-demand blood pressure estimates.

Key technologies involved include:

  • Photoplethysmography (PPG): Measures variations in light absorption caused by blood flow.
  • Pulse Transit Time (PTT): Calculates the time it takes for a pulse wave to travel between two arterial sites, which correlates with blood pressure.
  • Algorithmic Analysis: Converts raw sensor data into blood pressure readings using machine learning models trained on population data.

This combination allows Samsung watches to offer convenient blood pressure monitoring without the discomfort of cuff inflation.

Accuracy and Limitations of Samsung Blood Pressure Monitoring

While Samsung’s blood pressure measurement feature offers valuable insights, it is important to understand its limitations and accuracy considerations:

  • Calibration Dependency: Accuracy is highly dependent on the initial calibration with a standard cuff device. Without regular recalibration, readings may drift.
  • Environmental Factors: Movement, wrist positioning, skin tone, and ambient lighting can affect sensor performance and result accuracy.
  • Regulatory Approvals: Samsung blood pressure monitoring has received clearance in specific markets, such as South Korea and Europe, indicating it meets certain clinical standards, though it is not intended to replace medical-grade monitors.
  • Use Case: The feature is best suited for trend monitoring rather than diagnostic precision. Users should consult healthcare professionals for clinical decisions.
