ResMed S+: High Tech Help for Good Night’s Sleep


ResMed S+ has a free downloadable app from the Apple Store or Google Play. This connects your smartphone via Bluetooth to the biomotion device. Your smartphone stores the night’s sleep data. In the morning, when you turn off the biomotion device, it automatically uploads data about your night to ResMed’s proprietary cloud for analysis and graphic display on your smartphone.

The only problem I had with making an account during setup was a very common one. The programmers do not tell you in advance what format the password should be in – capital letters, numbers, or special characters. So you end up with an error message. This is a very unnecessary aggravation where far too many applications fail to properly help the user through the sign up process.

While setting up the application you are asked a series of lifestyle questions such as: do you smoke, do you take medications, do you consume caffeine and alcohol drinks? You must also respond to the usual personal questions about height, weight, and neck size. All of this information factors into your sleep patterns. It took me less than four minutes to get through the necessary setup questions.



An on-screen guide helps with the all important positioning of the biomotion device. It must be no farther from the head of your bed than an arm’s length away. If you have a night stand beside your bed, that easily takes care of positioning. I read a few complaints that it took several nights to get the correct positioning for the biomotion device. I didn’t experience any difficulties from the first night through the next month of testing.


Each night you answer a series of questions about your day: how stressed you were (some), how long you exercised (none), how much caffeine you drank (one Pepsi), and how much alcohol did you drink (an ounce with dinner).

There is a Mind Clear option. You can make a voice or text note to yourself to help clear your mind of that “stuff” we all go to bed with that is tumbling about in our brains.

The part I enjoyed most is: Relax and Sleep. You choose from 10 sounds to fall asleep to, and the application and the biomotion device work in tandem to match the sounds to your breathing pattern. Over time, the sounds will slow down, using the rhythm to slow down your breathing rate and relaxing you for sleep. I found ocean waves onto the beach the most relaxing of the sound choices.

There is a feature called Smart Alarm. It wakes you when you go into light sleep. Overall, this is supposed to help you develop better sleep patterns. I did not care for the interruption of my night’s sleep and could not truly determine a benefit to this idea, so I only tried it twice during the month’s testing.

During the night, the biomotion device records the ambient lighting in the room, noises during the night, your breathing, and your positions while sleeping. The average person moves at least 30 times during the night. Older individuals often get up during the night to use the bathroom or get a small drink of water. For people with sleep apnea which deprives the brain of oxygen for a brief time, those additional disruptions in your good night’s sleep are increasingly dangerous.
