✅【Portable Pulse Oximeter】Featuring a patented soft silicone ring sensor, this oximeter offers comfortable finger wear while delivering accurate readings. It will not slip off your finger and continuously tracks blood oxygen saturation, heart rate and body movement throughout your sleep at night.
✅【Vibration Reminder】The SleepU oxygen monitor delivers gentle vibration alerts if your blood oxygen level drops below the preset threshold, prompting you to adjust your posture and maintain healthy blood oxygen levels during sleep. Threshold values can be customized in the APP.
✅【ViHealth Trend Reports】Via the ViHealth APP, SleepU generates trend reports for your blood oxygen saturation and heart rate. Reports can be saved as PDF files for printing or sharing. The APP offers optional paid membership, which does not affect normal use of all basic functions.
✅【Smart Data Management】Built-in memory supports standalone operation without a phone. Data syncs automatically to the APP once paired with your mobile device, and can also be transferred to a PC via the included cable. Unlimited storage space with no extra charges.
✅【Rechargeable & Energy-Saving】This sleep oxygen monitor provides up to 16 hours of use on a full charge. The oximeter has no physical buttons: it automatically starts measuring once worn, and powers off automatically 2 minutes after you remove your finger from the sensor.
