Breathing Variations

WARNING

The Instinct® Crossover device is not a medical device and is not intended for use in the diagnosis or monitoring of any medical condition. For more information on pulse oximeter accuracy, go to garmin.com/ataccuracy.

The optical heart rate sensor on the Instinct Crossover device has a pulse oximeter feature that can measure your overnight breathing variations. Breathing variation insights are provided to enhance awareness of your sleep environment and general wellness. Occasional or frequent breathing variations may be due to your individual lifestyle factors or your sleeping environment. Contact your doctor or healthcare provider if you're concerned about your level of breathing variations.

The sleep score glance displays your current breathing variations data.
NOTE: You may need to add the glance to your glances list (Customizing the Glance Loop).

On your Garmin Connect™ account, you can view additional details about breathing variations, including trends over multiple days.
