Most CPAP users check their myAir score in the morning, just like they check the weather. A green number means a good night. A yellow or red one means something went sideways. And when it drops, the follow-up questions are always the same: what does the number actually measure, why did it drop, and what can be done to bring it back up?
Quick answer: The myAir app scores last night's CPAP therapy on a scale of 0 to 100, based on four factors: how many hours you used the device, how well your mask sealed, how often your breathing was interrupted (your AHI), and how many times the mask came off during the night. A score of As a practical benchmark, 70 or above is a solid night. In our experience helping CPAP users at Sleeplay, most fully adapted users run in the 80s and 90s on a regular night.
Understanding each factor makes it much easier to act on a low score rather than to guess what went wrong. The practical fixes are more straightforward than most people expect.
1. What is the myAir app?
myAir is ResMed's free companion app for AirSense and AirCurve CPAP and BiPAP machines. After each therapy session, it pulls your sleep data from the previous night and turns it into a score from 0 to 100, along with a breakdown of the four categories that make up that score. The app is free to download for both iOS and Android. [2]
myAir receives your data through the machine's built-in cellular connection, so it needs cellular reception and the machine plugged into power. [4] Bluetooth pairing with the app is available on the AirSense 11. The AirCurve 11 and AirCurve 10 series are also compatible. The AirMini travel machine uses a separate app, the AirMini app (also from ResMed), which displays similar therapy data but operates independently of myAir. [7]
The app's real value is in pattern recognition (see our roundup of the best CPAP companion apps). A single low score on a rough night isn't something to worry about. But when the app shows a mask seal that has been dropping for three nights in a row, or an AHI that has climbed during allergy season, those are patterns worth paying attention to.
2. How to read your myAir score
Every morning, myAir grades the previous night's session on a scale of 0 to 100. A practical way to read the number is in three bands.
| Color | Score range | What it means |
|---|---|---|
| Red | Under 50 | Therapy did not work well last night. Multiple factors may have gone wrong at once. |
| Yellow | 50 to 69 | Some issues to fix. One or two factors likely pulled the score down. |
| Green | 70 to 100 | A good night. The device recorded consistent therapy hours, a solid seal, and stable breathing. |
CPAP users who are fully settled into therapy typically run in the high 80s to 90s on a regular night. If your score stays under 50 for more than two nights in a row, it's worth calling your DME supplier or sleep specialist to review your settings and fit.
Gabriel, Sleeplay CPAP Specialist: “Your myAir score is graded out of 100 and is broken down into 4 categories that show you how well your therapy went the night before.”
3. The 4 factors behind your myAir score
Every nightly score is built from four pieces, each contributing a slice of the 100-point total. Hours used carry the most weight by far. The other three (mask seal, events per hour, and mask on/off) are quality measures that make up the rest. Together, these four give you the full picture of last night's therapy in a single screen.
ResMed publishes the breakdown: usage hours are worth up to 70 points, mask seal up to 20, events per hour up to 5, and mask on/off events up to 5. [1]
Usage hours
Hours used is the highest-weighted factor in the myAir score. Four or more hours per night is the medical minimum most insurance plans and DME providers use to assess therapy compliance (Medicare's standard is at least 4 hours per night on 70% of nights in a 30-day window) [5]. Falling consistently below that threshold is the fastest way to pull the score down, regardless of how well everything else went.
"There is a cellular modem in the machine that will track everything for you. It is attached to myAir and can go on AirView, which a lot of the clinicians or suppliers will have access to, to locate your compliance if need be, for the insurance or for your doctor."
James Curles, Sleep Coach at Sleeplay, in ResMed AirSense 11: Your Ultimate Guide
The system tracks how many hours and minutes the device was actively delivering pressurized air during the night. The more consistent you are, the more those hours contribute to your total.
Mask seal
Mask seal reflects how well your mask maintained an airtight fit throughout the night. The app scores how much air leaked from your mask overnight. A low leak rate earns full points. A high leak rate means therapy air is escaping, reducing the effective pressure reaching your airway, even when the device runs all night.
If your seal score keeps dropping, take a look at our guide to reducing CPAP mask leaks for the most common causes and how to address them.
Events per hour (AHI)
Events per hour is your Apnea-Hypopnea Index (AHI): the average number of breathing interruptions the device detected each hour during therapy. This count includes full apneas (complete pauses in breathing) and hypopneas (partial reductions in airflow). A lower number means more stable breathing. Most sleep specialists aim for an AHI under 5 events per hour as a treatment target; 5 to 15 is classified as mild, 15 to 30 moderate, and over 30 severe sleep apnea. [6] [1]
For a deeper look at what different AHI ranges mean for your therapy, our AHI score guide walks through each tier.
Mask on/off
This factor tracks how many times the mask was removed during the night. Each removal interrupts therapy and reduces your total score. Frequent removals are almost always a sign of a specific discomfort: pressure that feels too strong during the first stage of sleep, a dry or irritated airway, or a seal issue that keeps disrupting rest. In most cases, the cause is fixable once you identify it.
4. How to improve your myAir score
If your myAir score has been sitting lower than you'd like, each of the four factors has a clear path to improvement. The highest-impact changes are often the simplest.
Add more hours
The number of hours used is weighted highest in the scoring formula, so adding even 30 minutes per night moves the needle more than almost anything else. Building a consistent pre-sleep routine with the mask on and addressing any discomfort that might prompt you to remove it early is the most direct approach.
Dry mouth is one of the most common reasons people cut therapy short overnight. Adjusting your humidifier settings or switching to a heated hose usually makes a noticeable difference. For a full walkthrough of CPAP therapy from setup to daily use, our CPAP therapy guide covers the whole process.
Improve your mask seal
Replacing your mask cushion every 1 to 2 months is the single most effective seal fix. Worn silicone loses its shape and stops sealing properly, even when the mask looks intact. If you've recently replaced the cushion and the seal is still poor, a sizing issue is the next thing to check. Mask liners can also help with position-related leaks if you tend to shift during sleep.
Our guide to reducing CPAP mask leaks walks through each cause in detail.
Lower your events per hour
If your AHI is consistently elevated, a pressure-setting adjustment is usually needed. That's a conversation to have with your sleep specialist, not a self-service change. Your doctor can review your detailed therapy data (not just the myAir summary) and decide whether a re-titration or a switch to auto-adjusting pressure makes sense.
Reduce mask removals
Frequent mask removals almost always trace back to a specific discomfort. Pressure that feels too high when you first fall asleep responds well to the ramp feature, which starts therapy at a lower pressure and gradually increases to your prescribed level. A dry or irritated airway usually improves with a humidifier or heated hose. A cushion swap addresses fit-related leaks that pull the mask loose.

5. Troubleshooting common myAir issues
The myAir app is generally reliable, but a few issues come up regularly. Most resolve in under a minute. [3]
The score is missing this morning
Cellular sync sometimes lags. Wait a few hours before assuming something is wrong. If the score still hasn't appeared, check that your machine has cellular reception and is plugged into power, and that Bluetooth pairing with the app is active (available on the AirSense 11 only; for older models, see our AirSense 10 guide). Confirm the device is plugged in, since machines upload therapy data after the session ends.
Data is delayed or incomplete
Restarting the machine clears most sync issues. Unplug it for 30 seconds, plug it back in, and let it reconnect to the network before checking the app again.
The app is not syncing
Log out of the myAir app and log back in. If that doesn't resolve it, re-pair the device by going to your account settings and re-entering the machine's serial number.
The machine is not showing up in the app
Double-check that the serial number in the app matches the number printed on the back of the machine. If the machine was recently replaced, the old device's serial number may still be linked to your account.
Account locked or forgotten password
Use ResMed's account recovery tool through the app's login screen. If your machine itself needs service or you need further support, the Sleeplay team is available to help.
FAQs
What is a good myAir score?
70 or higher is a solid night. A practical reading: under 50, therapy did not work well; 50 to 69, something to address; 70 to 100, a good night. Fully adapted users typically run in the high 80s to 90s. Under 50 two nights in a row is worth a call to your sleep specialist.
What are the 4 factors in the myAir score?
Per ResMed's published breakdown: hours used (up to 70 points), mask seal (up to 20), events per hour (your AHI, up to 5), and mask on/off events (up to 5). Hours used matter most, and they are the metric your insurance and DME provider track for compliance.
How do I improve my myAir score?
The biggest lever is hours used: even 30 more minutes per night lifts the score. Next is mask seal: replace cushions every 1 to 2 months, refit the mask, and consider liners. Events per hour usually need a pressure adjustment from your sleep specialist. Mask on/off improves as you fix discomfort with ramp, humidification, or a cushion swap.
Why is my myAir score 0 or missing?
Most often a sync issue, not a therapy issue. Wait a few hours, since cellular sync can lag, and keep the machine plugged in where it has cellular reception. Confirm the mask was on last night and the serial number in the app matches your machine. If it persists, log out and back in, or contact ResMed support.
Does myAir work with the AirMini?
Not directly. The AirMini uses a separate companion app called the AirMini app, also free from ResMed. The myAir app is for AirSense and AirCurve machines. The AirMini app shows similar therapy data including usage hours, seal, events per hour, and a daily score, so the experience is comparable.
What does events per hour mean on myAir?
It is your Apnea-Hypopnea Index (AHI): the average number of breathing interruptions the machine detected per hour. Under 5 is the standard treatment target, and myAir awards up to 5 points of your score for minimal events.
Is 0.7 events per hour good on CPAP?
Yes. Anything under 5 events per hour is within the treatment target, so 0.7 means your therapy controlled almost every breathing interruption. The number varies night to night, so watch the weekly trend instead of a single reading.
How do I improve my mask seal score on myAir?
Refit the cushion while the machine is running, keep headgear snug but not tight, wash the cushion daily to remove skin oils, and replace a worn cushion every 1 to 2 months. Persistent leaks usually mean the wrong cushion size.
