Blood Pressure Measurement


HUAWEI WATCH D packs intricate blood pressure components, like a mini pump and airbag, into a highly-compact form. The 2.5D curved glass shimmers and glimmers with each turn of the wrist, complementing a durable aluminum alloy frame, with two handy buttons to take you to your tasks.1


A Work of Accuracy

HUAWEI WATCH D features a margin of error within ±3 mm Hg*, made possible by a high-precision pressure sensor, meticulous pressure feedback controls, and less air-resistance. The macromolecular tensile strap, ergonomically-arced airbag, and butterfly clasp, are all designed to remain stable during inflation, to enhance the precision of impromptu blood pressure readings.1

Smart Blood Pressure Reminders

HUAWEI WATCH D allows you to set customized measurement plans, based on which it will send out blood pressure reminders at scheduled times, such as wakeup and bedtime, so that you can stay on top of your blood pressure as soon as it changes.

HUAWEI TruSeen™ 5.0+
Heart Rate Monitoring

HUAWEI TruSeen™ 5.0+ heart rate monitoring technology deploys eight photoelectric sensors deployed in a ring formation, with two groups of light sources, to boost anti-interference capabilities by converging different signals. The watch's ergonomic sapphire rear case curves gracefully around the wrist, while substantially reducing light interference. An updated algorithm tracks heart rate with greater precision via high-fidelity signal processing, with PVD-coated electrodes6 to provide a comfortable, skin-tight fit, for enhanced ECG readings.

Usage Guidelines

Measurement posture
The measurement posture refers to the posture that is maintained from the beginning of a measurement until the time when the device displays the measurement result. Any action that goes strays from the recommended posture may affect the measurement result. To ensure high accuracy, it is recommended that you remain seated for at least 5 minutes before conducting a measurement. The following are the guidelines for standard measurement posture:

Applicable wrist circumference

M-sized strap: 13.0–16.0 cm
L-sized strap: 16.1–20.0 cm
Note: If your wrist circumference exceeds 20.0 cm, the accuracy of blood pressure measurements may be affected.

1. Do not self-diagnose or treat yourself based on measurement results, as self-diagnosis may actually worsen your condition. Remember to follow the advice of medical professionals, and to send your results to medical professionals who are familiar with your health.

2. Do not wear the product during medical procedures, such as during magnetic resonance imaging (MRI) or the use of high-frequency medical devices. Keep the product away from any strong magnetic objects, or the product may fail.

3. The ECG feature on this product does not support asystole identification or ST segment detection.

4. In the event of arrhythmia (such as premature atrial or ventricular beats, or atrial fibrillation), bear in mind that the results may be inaccurate or inconclusive.

5. Diabetes, high cholesterol, and high blood pressure can affect peripheral circulation, and hence affect measurement results.

6. Blood pressure readings for users who suffer from blood circulation disorders or blood diseases are prone to error.

7. Avoid making newborns, infants who weigh less than 10 kg, or individuals who are unable to express themselves, wear or use this product.

8. The following groups should obtain blood pressure readings from this product, only under the supervision of a medical professional:
· People who suffer from limb shaking syndrome, or whose arms are unable to bend on their own
· People with wounds or inflammation on their arm or wrist
· People whose arm or wrist is subject to an infusion, blood transfusion, or a catheter insertion
· People who are currently wearing or using medical devices


1. If the airbag is excessively inflated, it may cause discomfort to your wrist, and result in blood stasis or paralysis in extreme cases. In the event of overinflation, you should remove the device.

2. This device is not suitable for users who have pacemakers or other implantable devices.

3. Avoid measuring your blood pressure on the device too often, as doing so may affect blood circulation.

4. Device capabilities may be affected by portable and RF communication devices. Avoid placing the device near or on top of other devices, as doing so may increase radiation and undermine anti-interference capabilities.

5. This product may cause adverse events, such as allergies. In this case, stop wearing it and consult with a medical professional.

6. Metal implants in measured body parts may cause abnormal ECG signals.

7. Not applicable under conditions where flammable anesthetic gas mixed with air, oxygen, or nitrogen oxide.

8. Make sure that the electromagnetic interference is less than 3 V/m. Common sources of interference include microwave ovens and X-rays.

9. Before conducting an ECG measurement, make sure that the electrode surface of the product is clean. If the measurement fails multiple times, clean nearby skin and fingers with an alcohol solution.

10. This product may cause an adverse reaction in a small number of individuals, due to allergies, environmental factors, long-term exposure to irritants such as soap water or sweat, and other factors.

11. The device's ECG feature is only applicable for heart rate measurement and arrhythmia detection.
