Pulse Oximeter
The Venu 2 series 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
(
Changing the Pulse Oximeter Tracking Mode, page 17
). For more information on pulse oximeter accuracy, go

Getting Pulse Oximeter Readings
You can manually begin a pulse oximeter reading from the pulse oximeter glance. 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 glance to the glance loop (
Customizing the Glances, page 21
).
1 While you are sitting or inactive, swipe up or down to view the pulse oximeter glance.
2 Select the glance to begin the reading.
3 Hold the arm wearing the device at heart level while the device reads your blood oxygen saturation.
4 Keep still.
The device displays your oxygen saturation as a percentage, and a graph of your pulse oximeter readings
and heart rate values since midnight.
Changing the Pulse Oximeter Tracking Mode
1 Hold .
2 Select > Wrist Heart Rate > Pulse Ox > Tracking Mode.
3 Select an option:
• To turn on measurements while you are inactive during the day, select All Day.
NOTE: Turning on pulse oximeter tracking decreases battery life.
• To turn on continuous measurements while you sleep, select During Sleep.
NOTE: Unusual sleep positions can cause abnormally low sleep-time SpO2 readings.
• To turn off automatic measurements, select Off.
Tips for Erratic Pulse Oximeter Data
If the pulse oximeter data is erratic or does not appear, you can try these tips.
• Remain motionless while the device reads your blood oxygen saturation.
• Wear the device above your wrist bone. The device should be snug but comfortable.
• Hold the arm wearing the device at heart level while the device reads your blood oxygen saturation.
• Use a silicone band.
• Clean and dry your arm before putting on the device.
• Avoid wearing sunscreen, lotion, and insect repellent under the device.
• Avoid scratching the optical sensor on the back of the device.
• Rinse the device with fresh water after each workout.
Activity Tracking
The activity tracking feature records your daily step count, distance traveled, intensity minutes, floors climbed,
calories burned, and sleep statistics for each recorded day. Your calories burned includes your base
metabolism plus activity calories.
The number of steps taken during the day appears on the steps glance. The step count is updated periodically.
