Your most recent oxygen saturation reading.

A graph of your elevation readings for the last 24 hours.

Getting Pulse Oximeter Readings

You can manually begin a pulse oximeter reading by viewing the

pulse oximeter widget. The widget displays your most recent

blood oxygen saturation percentage, a graph of your hourly

average readings for the last 24 hours, and a graph of your

elevation for the last 24 hours.

NOTE: The first time you view the pulse oximeter widget, the

device must acquire satellite signals to determine your elevation.

You should go outside, and wait while the device locates

satellites.

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

the pulse oximeter widget.

Press START to view widget details and begin a pulse

oximeter reading.

Remain motionless for up to 30 seconds.

NOTE: If you are too active for the watch to get a pulse

oximeter reading, a message appears instead of a

percentage. You can check again after several minutes of

inactivity. For best results, hold the arm wearing the device at

heart level while the device reads your blood oxygen

saturation.

Press DOWN to view a graph of your pulse oximeter

readings for the last seven days.

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 .

Select Options > Pulse Ox Mode > During Sleep.

Turning On All-Day Acclimation Mode

From the pulse oximeter widget, hold .

Select Options > Pulse Ox Mode > All Day.

The device automatically analyzes your oxygen saturation

throughout the day, when you are not moving.

NOTE: Turning on all-day acclimation mode decreases

battery life.

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.

Viewing Your Heart Rate Variability Stress

Score

Before you can perform the heart rate variability (HRV) stress

test, you must put on a Garmin chest heart rate monitor and pair

it with your device (Pairing Your Wireless Sensors, page 29).

Your HRV stress score 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

you perform. The stress score range is 1 to 100, where 1 is a

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

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

ready for a tough training run or yoga.

TIP: Garmin recommends that you measure your stress score

before you exercise, at approximately the same time, and under

the same conditions every day. You can view previous results

on your Garmin Connect account.

Select START > DOWN > HRV Stress > START.

Follow the onscreen instructions.

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 (Tips for Improved Body Battery Data,

page 21).

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.

Press 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 30).

Press START to view a graph of your body battery level

since midnight.

Press DOWN to view a combined graph of your Body Battery

and stress levels.

Blue bars indicate periods of rest. Orange bars indicate

periods of stress. Gray bars indicate times when you were

too active to determine your stress level.
