How long does S+ take to start giving me feedback and suggestions on how to help improve my sleep?

You’ll start receiving tailored feedback after your first night’s sleep, with guidance targeting your bedroom’s sleep conditions.

Is it safe to use S+ when I am pregnant?

Yes, the S+ unit has not been found to pose any health risks during pregnancy to either mother or child.

Back to Questions Back to Categories

Is S+ designed to monitor the sleep of children?

No, S+ is not designed to monitor children’s sleep. Children naturally have a lower body mass index (BMI) than adults. A low BMI may not allow the S+ unit to successfully monitor a child’s breathing rate. Children also inherently move a lot more in their sleep compared to adults, and this would produce an inaccurate sleep score.

Does the unit require a power outlet to run or is a battery sufficient?

Yes, the S+ unit must be connected to a power source to function. It is not a battery-powered product. A power supply unit and USB power cable are provided with the S+.

Is the S+ sensor technology harmful to my children or pets?

No, the sensor technology in the S+ is not known to be harmful to children or pets, and meets with current international safety standards for electronic devices.

I have a pet that also sleeps on my bed. Will this affect the information I get?

If your pets sleep either on top of you, or between you and the S+ unit, you may receive erroneous results.

Does the S+ app work with my CPAP machine?

No. The S+ app is designed to monitor how long you spend in each stage of sleep based on your breathing and body movement and requires an S+ unit to use most features. The S+ app does not work with any CPAP machine. If you have a ResMed Air10(tm) machine you can use myAir to track your CPAP treatment. Learn more at myair.resmed.com

Can I use the S+ and myAir at the same time?
