Viewing Your SpO2 Readings in Flight
WARNING
The SpO2 readings are intended for backup information only. Always defer to applicable flight instruments for
primary awareness.
The D2 Air X10 watch has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood (SpO2).
Knowing your oxygen saturation can help you determine how your body is adjusting to high altitudes. As your
altitude increases, the level of oxygen in your blood can decrease. During a flight, the watch automatically takes
pulse oximeter readings more frequently, so you can monitor your SpO2 percentage.
TIP: You can improve the accuracy of your SpO2 readings by turning on all-day acclimation mode in the pulse
oximeter glance settings (Changing the Pulse Oximeter Tracking Mode, page 26).
1 Start a FLY activity.
2 Swipe up or down to scroll through the data screens.
Your most recent reading appears as an oxygen saturation percentage.
NOTE: If you are too active for the watch to determine your oxygen saturation, dashes appear instead of a
percentage. You should remain stationary for up to 30 seconds while the watch reads your blood oxygen
saturation.

About Heart Rate Zones
Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their
level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted heart
rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
Setting Your Heart Rate Zones
The watch uses your user profile information from the initial setup to determine your default heart rate zones.
The watch has separate heart rate zones for running and cycling. For the most accurate calorie data during your
activity, you should set your maximum heart rate. You can also set each heart rate zone. You can manually
adjust your zones on the watch or using your Garmin Connect account.

Fitness Goals
Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying
these principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table (
determine the best heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms
and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is
220 minus your age.

About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body
weight at your maximum performance. In simple terms, VO2 max. is an indication of cardiovascular strength
and should increase as your level of fitness improves.
On the watch, your VO2 max. estimate appears as a number and description. On your Garmin Connect account,
you can view additional details about your VO2 max. estimate.
VO2 max. data is provided by Firstbeat Analytics™. VO2 max. analysis is provided with permission from The
Cooper Institute®. For more information, see the appendix (VO2 Max. Standard Ratings, page 72), and go to

Pulse Oximeter
The D2 Air X10 watch 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 watch 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 watch, 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 26). For more information on pulse oximeter accuracy, go
to garmin.com/ataccuracy.
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 watch 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 31).
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 watch reads your blood oxygen saturation.
• Wear the watch above your wrist bone. The watch should be snug but comfortable.
• Hold the arm wearing the watch at heart level while the watch reads your blood oxygen saturation.
• Use a silicone or nylon band.
• Clean and dry your arm before putting on the watch.
• Avoid wearing sunscreen, lotion, and insect repellent under the watch.
• Avoid scratching the optical sensor on the back of the watch.
• Rinse the watch 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.
For more information about activity tracking and fitness metric accuracy, go to
26Activity Tracking
garmin.com/ataccuracy.
Page 33
Auto Goal
Your watch creates a daily step goal automatically, based on your previous activity levels. As you move during
the day, the watch shows your progress toward your daily goal .
If you choose not to use the auto goal feature, you can set a personalized step goal on your Garmin Connect
account.
Using the Move Alert
Sitting for prolonged periods of time can trigger undesirable metabolic state changes. The move alert reminds
you to keep moving. After one hour of inactivity, a message appears, and the red bar appears on the steps
glance. Additional segments appear after every 15 minutes of inactivity. The watch also vibrates, if vibration is
turned on (System Settings, page 59).
Go for a short walk (at least a couple of minutes) to reset the move alert.
Sleep Tracking
While you are sleeping, the watch automatically detects your sleep and monitors your movement during your
normal sleep hours. You can set your normal sleep hours in the user settings on your Garmin Connect account.
Sleep statistics include total hours of sleep, sleep stages, sleep movement, and sleep score. You can view your
sleep statistics on your Garmin Connect account.
NOTE: Naps are not added to your sleep statistics. You can use do not disturb mode to turn off notifications
and alerts, with the exception of alarms (Using Do Not Disturb Mode, page 11).
Intensity Minutes
To improve your health, organizations such as the World Health Organization recommend at least 150 minutes
per week of moderate intensity activity, such as brisk walking, or 75 minutes per week of vigorous intensity
activity, such as running.
The watch monitors your activity intensity and tracks your time spent participating in moderate to vigorous
intensity activities (heart rate data is required to quantify vigorous intensity). The watch adds the amount of
moderate activity minutes with the amount of vigorous activity minutes. Your total vigorous intensity minutes
are doubled when added.
Earning Intensity Minutes
Your D2 Air X10 watch calculates intensity minutes by comparing your heart rate data to your average resting
heart rate. If heart rate is turned off, the watch calculates moderate intensity minutes by analyzing your steps
per minute.
• Start a timed activity for the most accurate calculation of intensity minutes.
• Wear your watch all day and night for the most accurate resting heart rate.
