Blood pressure measurements on my HUAWEI WATCH D/D2 fail or generate no results

During blood pressure measurement, the watch shows 0 mmHg or the airbag doesn't inflate

If the watch has been powered off or disconnected from your phone for a long time, the time display may be incorrect, and it may not show blood pressure readings properly. Restore the Bluetooth connection by pairing your watch again with your phone or with Huawei Health, and try again.

1. Please refer to An inflation error occurs when I measure my blood pressure on HUAWEI WATCH D2 for handling suggestions.
2. Blood pressure measurements may fail or generate no results if water or dust having entered the airbag or air pathway in your watch. In this case, clean the air pressure hole and try again. For the video tutorial, refer to HUAWEI WATCH D2 Cleaning & care tips.
3. If the issue persists, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.

The prompt "Deflating... Cuff pressure out of range. Measurement ended. Try again later." displays

The pump supports a measurement range of 0–300 mmHg (0–40 kPa). Pressure values outside of this range are not supported on this product. It is recommended that you take a break and try again after ensuring the device is worn tightly.

Ensure the airbag watch strap matches the wrist circumference setting by opening the Blood pressure app, swiping up to the last screen, and going to Settings > Wrist circumference.

If the issue persists, it is recommended that you visit a nearby service center for inspection.

The prompt "Wear the watch during the measurement." displays for blood pressure measurement

Blood pressure, heart rate, and SpO2 monitoring accuracy may be affected by factors like arm hair, tattoos, and scars, which can even lead to unsuccessful measurements. Avoid wearing your watch over a tattoo or scar. Typically, the watch should be worn about two fingers' width away from the palm, not over the ulna styloid protrusion.

• During a measurement, bend your elbow with your palm facing your chest. Hold your elbow with your other palm and make sure your watch is level with your heart, but not pressing against the airbag or your chest. Your wrist and palm should be naturally relaxed. Do not clench your fist or cross your legs. Keep both feet flat on the ground.
• It is recommended that you rest for at least 5 minutes before a measurement, to ensure optimal accuracy. Blood pressure measurements may fail due to body movements, such as those caused by deep breathing, coughing, shaking, yawning, sneezing, and speaking. Please stay still during measurements.
• Other factors affecting blood pressure measurements:

  A cold wrist can impede blood flow, leading to a weak pulse and measurement failure. In such cases, warm your wrist and try again.

  If you have a very weak pulse due to severe anemia, do not use this product to measure your blood pressure.

  Blood pressure measurements might not succeed or produce any result due to unstable posture caused by conditions such as Parkinson's disease, the aftereffects of cerebrovascular disease, and frequent premature beats.

  Severe arteriosclerosis may cause blood pressure measurements to fail or generate no results.

  An abnormally low or high heart rate (below 40 or above 180 bpm) can cause blood pressure measurements to fail or generate no results.

Arrhythmia could cause blood pressure measurements to fail or generate no results. Try having someone else use the watch to see if it works properly.
