While some smartwatches claim to measure blood pressure, it's important to understand how they work and their accuracy. Smartwatches that measure blood pressure typically do so in one of two ways: using an inflatable cuff or using sensors to estimate blood pressure.
Checking blood pressure using a smart watch with an inflatable cuff:
- Preparation: Make sure your smartwatch is properly fitted and charged.
- Activation: Initiate the blood pressure monitoring function on your smartwatch. This usually involves navigating to the appropriate app or setting.
- Inflation: The watch's cuff will inflate, similar to a traditional blood pressure monitor.
- Measurement: The watch measures your blood pressure as the cuff inflates and deflates.
- Results: Your blood pressure reading (systolic and diastolic) will be displayed on the watch's screen.
Important Considerations:
- Accuracy: Smartwatch blood pressure measurements, especially those without inflatable cuffs, should not be considered a substitute for readings taken by a medical professional using a validated blood pressure monitor. Factors like movement, skin tone, and proper fit can affect accuracy.
- Calibration: Some smartwatches that use inflatable cuffs require calibration with a traditional blood pressure monitor for accuracy. Follow the manufacturer's instructions for calibration.
- FDA Approval: It's important to check if the smartwatch is FDA-approved for blood pressure monitoring, which ensures a certain level of accuracy and reliability.
- Consult Your Doctor: Always discuss blood pressure readings from your smartwatch with your doctor, especially if you have any concerns about your blood pressure.
