Getting Pulse Oximeter Readings

You can manually begin a pulse oximeter reading on your

device at any time. The accuracy of the reading can vary based

on your blood flow, the device placement on your wrist, and your

stillness.

Wear the device above your wrist bone.

The device should be snug but comfortable.

Select UP or DOWN to view the pulse oximeter widget.

Select START.

Hold the arm wearing the device at heart level while the

device reads your blood oxygen saturation.

Keep still.

The device displays your oxygen saturation as a percentage.

NOTE: You can customize the pulse oximeter settings in your

Garmin Connect account.

Turning On Pulse Oximeter Sleep Tracking

You can set your device to continuously measure your blood

oxygen saturation while you sleep.

NOTE: Unusual sleep positions can cause abnormally low

sleep-time SpO2 readings.

From the pulse oximeter widget, hold UP.

Select Sleep Pulse Ox > On.

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.

Heart Rate Variability and Stress Level

Stress level is the result of a three-minute test performed while

standing still, where the Forerunner device analyzes heart rate

variability to determine your overall stress. Training, sleep,

nutrition, and general life stress all impact how a runner

performs. The stress level range is from 1 to 100, where 1 is a

very low stress state and 100 is a very high stress state.

Knowing your stress level can help you decide if your body is

ready for a tough training run or yoga.

Using the Stress Level Widget

The stress level widget displays your current stress level and a

graph of your stress level for the last several hours. It can also

guide you through a breathing activity to help you relax.

While you are sitting or inactive, select UP or DOWN to view

the stress level widget.

Select START.

• If your stress level is in the low or medium range, a graph

appears showing your stress level for the last four hours.

TIP: To start a relaxation activity from the graph, select

DOWN > START, and enter a duration in minutes.

• If your stress level is in the high range, a message

appears asking you to begin a relaxation activity.

Select an option:

• View your stress level graph.

NOTE: Blue bars indicate periods of rest. Yellow bars

indicate periods of stress. Gray bars indicate times when

you were too active to determine your stress level.

• Select Yes to start the relaxation activity, and enter a

duration in minutes.

• Select No to bypass the relaxation activity and view the

stress level graph.

Body Battery

Your device analyzes your heart rate variability, stress level,

sleep quality, and activity data to determine your overall Body

Battery level. Like a gas gauge on a car, it indicates your

amount of available reserve energy. The Body Battery level

range is from 0 to 100, where 0 to 25 is low reserve energy, 26

to 50 is medium reserve energy, 51 to 75 is high reserve energy,

and 76 to 100 is very high reserve energy.

You can sync your device with your Garmin Connect account to

view your most up-to-date Body Battery level, long-term trends,

and additional details

Viewing the Body Battery Widget

The Body Battery widget displays your current Body Battery

level and a graph of your Body Battery level for the last several

hours.

Select UP or DOWN to view the Body Battery widget.

NOTE: You may need to add the widget to your widget loop

(Customizing the Widget Loop, page

Select START to view a combined graph of your Body

Battery and stress level.

Blue bars indicate periods of rest. Orange bars indicate

periods of stress. Gray bars indicate times that you were too

active to determine your stress level.
