What if the little number on your phone each morning could tell you whether your sleep apnea therapy is actually working? That is the basic promise behind myAir, the patient app from ResMed that turns nightly breathing-machine data into a daily score. For millions of people using CPAP and bilevel therapy, it has become a morning ritual: wake up, open the app, check the number, feel good or feel worried.
But the score is often misunderstood. Some users treat it as a medical report card. Others ignore it entirely because they are not sure what it measures. The reality sits somewhere in between, and understanding the difference matters if you want to get real value from the app instead of just a daily thumbs-up.
This guide breaks down what myAir is, how the data gets from your bedside to your phone, what the score does and does not measure, where the app falls short, and how to use it without letting a green circle run your life.
What myAir Actually Is
myAir is a patient-facing app and web portal from ResMed. It works with ResMed AirSense and AirCurve machines, the same devices many people receive after a sleep study confirms obstructive sleep apnea or another breathing disorder.
The app shows nightly therapy data: how long you used the machine, how well the mask sealed, how many breathing events occurred per hour, and how many times you took the mask off. It rolls these into a daily score, usually presented on a scale of 0 to 100.
It is important to understand what myAir is not. It is a patient-engagement tool, not a clinical record system. It is designed to educate and motivate, not to diagnose or replace a clinician’s review. The score is a summary, and it is not a validated clinical index in the way that, say, the apnea-hypopnea index is.
That distinction sounds academic, but it has practical consequences. A perfect score does not prove your therapy is optimally tuned. A low score does not automatically mean something is dangerously wrong. It is a signal, not a verdict.
How Your Data Travels From Bedside to Phone
One of the most common points of confusion is how myAir gets its information. Nobody plugs the machine into a phone each morning. The data moves on its own.
Most AirSense 10, AirSense 11, and AirCurve devices include a built-in cellular modem. Overnight, the machine records therapy data and transmits it to ResMed’s cloud platform, AirView. The myAir app then pulls that data and displays it. Some models and regions also support Wi-Fi or Bluetooth syncing to a phone.
This creates a chain with several links, and any weak link can cause problems:
- The machine records the data correctly.
- The modem connects to a cellular network.
- The data reaches ResMed’s cloud.
- The app syncs and displays the results.
When the app shows nothing, the machine is rarely the culprit. More often, the modem could not find a signal, the sync simply has not happened yet, or the account is not linked properly. Users in areas with poor cellular coverage report this more frequently, though that pattern comes from patient forums rather than formal studies.
A practical tip that solves a surprising number of “my app is broken” complaints: give it time. Data does not always upload the instant you take the mask off. Waiting until later in the morning, or checking again after a few hours, resolves many sync gaps. If the app stays empty for more than a day or two, that is when a call to the equipment provider makes sense.
myAir vs. AirView: Two Different Tools
People mix these up constantly, and it causes real frustration. Here is the short version.
| Feature | myAir | AirView |
|---|---|---|
| Designed for | Patients | Clinicians and care teams |
| Main purpose | Motivation and daily feedback | Clinical review and compliance reporting |
| Data shown | Simplified nightly summary and score | Detailed therapy data, trends, and reports |
| Typical user | Person using the CPAP machine | Sleep clinician, doctor, equipment provider |
If you have ever wondered why your doctor seems to know more about your therapy than the app shows you, this is why. The clinician is likely looking at AirView, which contains far more detail than the patient app. myAir is the highlight reel; AirView is the full game footage.
There is also a third data source worth knowing about: the SD card inside the machine. Sleep clinicians often use SD-card data or AirView reports for titration decisions and compliance documentation. myAir data is not a substitute for either. If a clinician asks for a detailed review, the app on your phone is not the tool they will reach for.
What the Daily Score Measures
The myAir score combines several elements, weighted heavily toward usage. The exact weighting is not something to quote from memory, and it can change, but the components are consistent:
- Usage hours: how long the machine ran while you wore the mask.
- Mask seal: how much air leaked around the mask.
- Events per hour: the device’s estimate of breathing events during therapy.
- Mask on/off: how many times the mask was removed.
Usage dominates the score. That reflects how adherence is measured in clinical and insurance contexts. In the United States, CPAP adherence is commonly defined as at least 4 hours per night on at least 70% of nights, often assessed over a 30-day window. This threshold is widely used by insurers and sleep clinicians and is sometimes called the Medicare adherence criterion. myAir displays usage in a way that lets patients compare themselves to that benchmark.
That is genuinely useful. If you are hovering near four hours a night, the app makes the gap visible before it becomes a coverage problem.
Why a High Score Is Not a Clean Bill of Health
Here is where people get into trouble. A score of 95 feels like proof that everything is fine. It is not proof of anything except that the machine was used, the leak was modest, and the device’s event estimate was low.
Consider a few scenarios where the score and reality diverge:
The high score with a bad night. Someone can score well on usage and leak while still waking up exhausted. The score does not measure sleep quality, comfort, or whether the pressure setting is ideal for that person.
The low score from a rough night. A cold, a stuffy nose, or a mask that slipped at 3 a.m. can drag the number down. One bad night means little on its own. Trends over weeks matter far more than any single morning.
The leak problem the score underplays. Mask leak is one component, and a moderate leak might barely dent the score while still disturbing sleep and reducing therapy effectiveness. Leaks are one of the most common practical problems with CPAP, and the app’s summary can make them look less significant than they are.
The pattern to watch is not the daily number. It is the direction of travel over two to four weeks. Falling usage, rising leak, or a creeping event count are the signals worth acting on.
Common Mistakes and What Actually Works
A few habits separate people who get value from myAir from people who end up frustrated by it.
Mistake one: checking the score the second you wake up. Sync delays make this unreliable. Check later in the morning.
Mistake two: chasing a perfect score. The score is a motivational tool. Treating it as a target to optimize can lead to obsessive checking and anxiety, which is the opposite of what a sleep therapy app should produce.
Mistake three: assuming the app replaces the clinician. myAir cannot tell you whether your pressure is right. It cannot diagnose central events or interpret complex patterns. It is a summary, and summaries leave things out.
Mistake four: ignoring mask fit. Small adjustments to mask fit, cushion condition, and headgear tension often improve both the score and how the person actually feels. The app flags leak, but the fix happens at the bedside.
What works: look at weekly patterns, not daily numbers. Note changes in how you feel alongside the data. Bring specific observations to appointments. If the app shows a persistent problem, say so directly rather than hoping the clinician notices.
Privacy and Data Considerations
myAir handles health data, and that carries legal weight. In the United States, health data handled by covered entities and their business associates falls under the HIPAA Privacy Rule, which sets rules for how protected health information is used and disclosed. In the European Union, health data is treated as a special category under the General Data Protection Regulation (GDPR), specifically Article 9, which requires a stronger legal basis for processing.
For patients, the practical takeaways are straightforward. Read the privacy policy that applies to your account rather than assuming. Be aware that your therapy data is stored in a cloud system and shared with your care team. And if you travel or move between countries, note that availability and features of myAir can vary by region, so what works at home may not work identically abroad.
Who Can Use myAir
myAir is generally available to patients whose ResMed device is connected and whose provider or care setting is enrolled. Availability and specific features vary by country, and the details change over time. If the app will not let you register, the issue is usually account linkage or regional availability rather than a problem with the machine itself.
It is also worth being clear about what myAir is not for. It is not a tool for adjusting your own pressure settings. Pressure changes should come from a clinician who has reviewed the fuller data. The app gives you visibility; it does not give you a license to tinker.
Conclusion
myAir is a genuinely useful window into CPAP therapy, and it is at its best when treated as exactly that: a window, not a verdict. It shows usage, leak, and event trends in plain language, and it makes the four-hour adherence benchmark visible in a way that helps people stay on track. What it cannot do is tell you whether your therapy is optimally tuned, whether your sleep quality is good, or whether your pressure settings are right. Those questions belong to your clinician and the fuller data they can access.
The smart approach is simple. Check the app, but look at trends rather than single nights. Use the score as a nudge, not a grade. Bring real observations to your care team. And if the app misbehaves, remember that sync problems are usually about connectivity or accounts, not about the machine failing. Used that way, myAir earns its place in the morning routine without taking over the day.
Frequently Asked Questions
What does the myAir score actually measure?
The score combines usage hours, mask seal, events per hour, and mask on/off counts, with usage weighted most heavily. It is a motivational summary rather than a validated clinical index, so it should not be read as a medical assessment of therapy quality.
Is myAir the same as AirView?
No. myAir is designed for patients and shows a simplified nightly summary. AirView is the clinician-facing platform that contains far more detailed therapy data and is used for clinical review and compliance reporting. Your care team likely reviews AirView, not your app.
Why is my myAir app not showing last night’s data?
Most often the data simply has not synced yet. The machine transmits over its built-in modem to ResMed’s cloud, and the app pulls from there, so delays are common. Poor cellular coverage can also interrupt uploads. Wait a few hours before assuming something is wrong, and contact your equipment provider if the gap lasts more than a day or two.
What adherence threshold does myAir relate to?
In the United States, CPAP adherence is commonly defined as at least 4 hours per night on at least 70% of nights, often measured over a 30-day window. This benchmark is widely used by insurers and sleep clinicians, and myAir displays usage so patients can compare themselves against it.
Can a good myAir score mean my therapy is working perfectly?
Not necessarily. The score does not measure sleep quality, comfort, or whether your pressure setting is ideal. Someone can score well and still feel exhausted, or score lower after one rough night. Trends over several weeks, combined with how you feel, are more meaningful than any single day’s number.
Can I use myAir to change my own pressure settings?
No. myAir gives visibility into therapy data but is not designed for adjusting settings. Pressure changes should be made by a clinician who has reviewed the fuller data available through AirView or the device’s SD card.
