Heart Rate Features
The vívomove 3/3S device has a heart rate menu, enabling you to view wrist-based heart rate data.
Monitors the saturation of oxygen in your blood. Knowing your oxygen saturation can help you determine
how your body is adapting to exercise and stress.
NOTE: The pulse oximeter sensor is located on the back of the device.
Displays your current VO2 max., which is an indication of athletic performance and should increase as
your level of fitness improves.
Broadcasts your current heart rate to a paired Garmin
®
device.
Pulse Oximeter
The device has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood. Knowing your
oxygen saturation can be valuable in understanding your overall health and help you determine how your body is
adapting to altitude. Your device gauges your blood oxygen level by shining light into the skin and checking how
much light is absorbed. This is referred to as SpO
2
.
On the device, your pulse oximeter readings appear as an SpO
2
percentage. On your Garmin Connect account,
you can view additional details about your pulse oximeter readings, including trends over multiple days (
On Pulse Oximeter Sleep Tracking, page 13
). For more information on pulse oximeter accuracy, go to
Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading on your device at any time. The accuracy of these readings
can vary based on your blood flow, the device placement on your wrist, and your stillness.

2
readings.
