Pulse Oximeter
The Garmin device, accessories, heart rate monitor,
pulse oximeter sensor, and related data are intended
to be used only for recreational purposes and not for
medical purposes, and are not intended to diagnose,
monitor, treat, cure, or prevent any disease or
condition.
The vívoactive device has a wrist-based pulse
oximeter to gauge the saturation of oxygen in your
blood. Knowing your oxygen saturation can help you
determine how your body is adapting to exercise and
stress. 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 SpO2.
On the device, your pulse oximeter readings appear
as an SpO2 percentage. On your Garmin Connect
account, you can view additional details about your
pulse oximeter readings, including trends over multiple
days
(Changing the Pulse Oximeter Tracking Mode,
page 9). For more information on pulse oximeter
accuracy, go to garmin.com/ataccuracy.
Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading by
viewing the pulse oximeter widget. The accuracy of the
pulse oximeter reading can vary based on your blood
flow, the device placement on your wrist, and your
stillness.
NOTE: You may need to add the pulse oximeter widget

to view the pulse oximeter widget.
2 Hold the arm wearing the device at heart level
while the device reads your blood oxygen
saturation.
3 Keep still.
The device displays your oxygen saturation as a
percentage, and a graph of your pulse oximeter
readings and heart rate values for the last four
hours.

Tips for Erratic Pulse Oximeter Data
If the pulse oximeter data is erratic or does not appear,
you can try these tips.
y Remain motionless while the device reads your
blood oxygen saturation.
y Wear the device above your wrist bone. The device
should be snug but comfortable.
y Hold the arm wearing the device at heart level
while the device reads your blood oxygen
saturation.
y Use a silicone band.
y Clean and dry your arm before putting on the
device.
y Avoid wearing sunscreen, lotion, and insect
repellent under the device.
y Avoid scratching the optical sensor on the back of
the device.
y Rinse the device with fresh water after each
workout.
