`n How to Use the ResMed myAir App: Every Metric Explained by an RRT
Your CPAP machine collects detailed data every single night — AHI, leak rate, pressure delivered, usage hours, flow patterns. Most patients never look at it. The ones who do look at it often don't know what they're seeing. The ResMed myAir app turns that raw therapy data into a daily score and visual dashboard that you can actually use to understand, optimize, and advocate for your own therapy.
This is the complete guide to myAir — setup, every metric explained, how to read your score, what good data looks like, and how to use the information to have better conversations with your care team. Written by a licensed Registered Respiratory Therapist with ICU and critical care experience who reads CPAP data clinically every day.
Which ResMed Devices Work With myAir
myAir is compatible with ResMed's cellular-enabled AirSense and AirCurve devices. Before setting up the app, confirm your device is supported:
| Device | myAir Compatible | Data Transmission |
|---|---|---|
| AirSense 10 AutoSet | ✅ Yes | Cellular (built-in) |
| AirSense 10 Elite | ✅ Yes | Cellular (built-in) |
| AirSense 10 CPAP | ✅ Yes | Cellular (built-in) |
| AirSense 11 AutoSet | ✅ Yes | Cellular (built-in) |
| AirSense 11 AutoSet for Her | ✅ Yes | Cellular (built-in) |
| AirCurve 10 VAuto / S / ASV | ✅ Yes | Cellular (built-in) |
| AirMini (travel CPAP) | ✅ Yes (via Bluetooth) | Bluetooth to phone |
| S9 series (older) | ❌ No | SD card only |
The AirSense 10 and 11 have cellular modems built in and upload data automatically overnight — no phone pairing or manual sync required. The AirMini uses Bluetooth to your phone and requires the AirMini app, which feeds into myAir. For a comparison of the AirSense 10 and 11 platforms, see our guide on ResMed AirSense 10 vs AirSense 11.
Setting Up myAir: Step by Step
- Download the myAir app from the App Store (iOS) or Google Play (Android). Search "ResMed myAir" — it's free.
- Create a myAir account using your email address. Use an email you check regularly — myAir sends weekly summary reports.
- Enter your device serial number when prompted. The serial number is on a label on the bottom of your AirSense 10 or 11. It begins with a letter and is followed by digits.
- Confirm your device details — myAir will identify your specific model and therapy mode.
- Complete the onboarding questionnaire — myAir asks about your therapy start date, equipment (mask type, humidifier), and comfort preferences. Answer accurately; this personalizes the coaching tips.
- Wait for your first night of data. After your first night using the connected device, data uploads automatically and appears in the app by mid-morning. Your first myAir score will populate after that first complete session.
Understanding Your myAir Score
myAir generates a daily score from 0 to 100 based on four components weighted equally. Understanding the scoring logic tells you exactly where to focus your improvement efforts.
| Score Component | Weight | What It Measures | Maximum Points |
|---|---|---|---|
| Usage hours | 25% | Total hours CPAP was used that night | 25 points (achieved at 7+ hours) |
| Mask seal | 25% | Unintentional leak rate throughout the night | 25 points (achieved with minimal leak) |
| AHI events | 25% | Apnea-Hypopnea Index — events per hour | 25 points (achieved at AHI <5) |
| Mask on/off | 25% | Number of times mask was removed and replaced during the night | 25 points (0 removals = full score) |
Score Benchmarks
| Score Range | Interpretation | What to Do |
|---|---|---|
| 90–100 | Excellent — therapy working optimally | Maintain current routine |
| 70–89 | Good — minor issues affecting one component | Identify which component is lowest and target it |
| 50–69 | Fair — meaningful therapy gap present | Clinical review warranted; troubleshoot priority components |
| Below 50 | Poor — therapy significantly compromised | Contact your DME supplier or RT; settings review needed |
A score above 70 meets insurance compliance thresholds in most plans. A score consistently above 90 indicates therapy working at a clinical optimum. For the full clinical picture of what good AHI data looks like independent of the myAir score, see our guide on what is a good AHI on CPAP.
Every myAir Metric Explained
AHI (Apnea-Hypopnea Index)
AHI is the number of apnea and hypopnea events per hour of sleep. It is the primary clinical measure of how well your therapy is controlling your sleep apnea.
| AHI on CPAP | Clinical Interpretation |
|---|---|
| < 2.0 | Excellent control |
| 2.0 – 5.0 | Good control — within normal range |
| 5.0 – 10.0 | Borderline — may indicate pressure or mask issue |
| > 10.0 | Inadequate control — clinical review needed |
Mask Seal / Unintentional Leak
This metric shows the volume of air leaking from your mask unintentionally — not through the intentional vent in the mask, which is normal and expected, but through gaps at the cushion-to-face seal. Leak is measured in liters per minute (L/min).
| Leak Rate | myAir Rating | Clinical Significance |
|---|---|---|
| 0 – 24 L/min | Good seal | Normal range; full therapy effectiveness |
| 25 – 40 L/min | Fair seal | Marginal — monitor; refit if persistent |
| > 40 L/min | Poor seal | Clinically significant; mask fit adjustment needed |
Elevated leak is the most common score-reducer in myAir and the most fixable. See our complete guide on fixing CPAP mask leaks for the step-by-step fix protocol. Common causes: worn cushion (over 3 months old), wrong cushion size, overtightened headgear, or mouth breathing with a nasal mask.
Usage Hours
Total hours the CPAP was running with the mask on your face. This is different from total time in bed — if you put the mask on at 10 PM but don't fall asleep until 11 PM with the machine running, or if you remove the mask at 5 AM and sleep an additional 2 hours without it, only the masked time counts.
- 4 hours = insurance compliance minimum threshold (70% of nights)
- 6 hours = clinical minimum for meaningful cardiovascular and metabolic protection
- 7+ hours = full myAir usage score; optimal clinical benefit
If you're consistently removing the mask during the night, addressing the reason (mask discomfort, pressure discomfort, full bladder interruptions) increases usage hours more effectively than willpower alone. See our CPAP compliance guide for the behavioral strategies.
Mask On/Off Events
The number of times the mask was removed and replaced during the night. Zero removals is ideal. Each removal breaks the pressurized seal, allows airway events during the unmasked period, and indicates discomfort or behavioral factors worth investigating.
Frequent mask-on/off events are often driven by mask discomfort (pressure sores, leak-related dryness) or arousal-driven removal during partially conscious states. Address the underlying discomfort first — see our CPAP nose sore guide and complete side effects guide.
Reading the myAir Dashboard: What Every Screen Shows
Home Screen — Today's Score
The home screen displays your most recent night's score as a circular gauge, with the four component scores beneath it. This is your at-a-glance therapy health check. The color coding (green/yellow/red) on each component immediately identifies which metric is dragging your score.
7-Day and 30-Day Trend View
Tap the score gauge to expand to the trend view. This is clinically more valuable than the single-night score — it shows whether your therapy is consistently effective, intermittently compromised, or trending in a particular direction. Look for:
- Consistent high scores (85+): Therapy stable and effective
- Consistently low scores: Systematic problem — settings, equipment, or behavioral
- High variability: Intermittent problem — correlate with alcohol nights, illness, travel, sleep position
- Gradual downtrend: Equipment degrading (cushion aging, filter clogging) or progressive therapy needs change
Detailed Night View
Tapping any night in the trend view opens the detailed view for that night: hour-by-hour AHI, leak rate across the night, and pressure delivery (on APAP devices). This is where you identify when during the night problems occur:
- AHI spikes in the early morning hours (3–6 AM): Classic REM sleep pattern — REM is when obstructive events cluster; if this is severe, pressure may need to be higher or upper range expanded on APAP
- Leak spikes in the second half of the night: Often correlates with rolling supine (check sleep position) or jaw opening as muscle tone decreases with deeper sleep
- Sustained elevated pressure on APAP: Machine working hard throughout the night — may indicate pressure range ceiling is too low, or an exacerbating factor (alcohol, nasal congestion, positional)
Coaching Tips Section
myAir offers personalized coaching tips based on your data patterns. These are algorithm-generated and generally clinically sound for common issues. For complex or persistent problems, the tips are a starting point — a clinical review of your data by an RT provides more specific and actionable guidance than the app's automated suggestions.
Using myAir Data to Improve Your Therapy
The Weekly Review Habit
The most valuable use of myAir is a brief weekly review of your 7-day trend — not obsessing over single-night scores, but identifying patterns that reveal actionable problems. Take 5 minutes every Sunday morning to:
- Note your 7-day average AHI — is it under 5?
- Note your 7-day average leak — is it in the good seal range?
- Identify any nights with significantly worse scores — what was different about those nights?
- Note your average usage hours — are you consistently hitting 6+?
Correlating Data With Lifestyle Factors
myAir data becomes most powerful when you correlate it with lifestyle factors. Common patterns worth tracking:
| Pattern in myAir Data | Likely Lifestyle Correlation | Action |
|---|---|---|
| AHI elevated on specific nights | Alcohol consumption 1–3 hours before bed | Extend alcohol-to-bedtime gap to 4+ hours |
| Leak elevated and dry mouth worse on same nights | Mouth breathing — jaw opening during sleep | Add chin strap or transition to full face mask |
| Lower scores on travel nights | Different sleep environment, no humidifier, positional changes | Travel CPAP with humidifier; maintain sleep hygiene |
| Worse scores during allergy season | Nasal congestion increasing mouth breathing and AHI | Nasal saline rinse; discuss nasal steroid spray with physician |
| Gradual AHI increase over months | Weight gain, cushion aging, or progressive pressure needs | Replace cushion; schedule APAP pressure review |
Taking Data to Your Care Team
myAir data is clinically accessible to your prescribing physician and DME supplier through the AirView platform — the provider-facing portal that syncs with the same data your myAir app shows. Before any CPAP-related appointment:
- Screenshot your 30-day trend from myAir to bring visually
- Note any specific nights with significantly elevated AHI or leak that you want to discuss
- Write down any symptoms (dry mouth, morning headaches, persistent fatigue) and note whether they correlate with low-score nights in the app
A provider who can see your AirView data alongside your subjective report can make much more targeted therapy adjustments than one working from symptom description alone.
myAir Troubleshooting: Common Problems
| Problem | Cause | Fix |
|---|---|---|
| No data appearing after first night | Device not registered correctly; cellular signal issue | Verify serial number in account settings; ensure device was plugged in overnight (cellular upload requires power) |
| Data appears days late | Cellular signal weak in bedroom location | Move device to location with better signal; data will eventually upload when signal available |
| Score seems wrong — felt I slept well but scored poorly | myAir measures objective data, not subjective sleep quality | Check which component scored low and address that specific metric; subjective feel and objective data sometimes diverge |
| myAir shows AHI but physician's system shows different number | AirView and myAir occasionally display slightly different AHI calculations | AirView is the clinical reference; both are derived from the same raw data |
| App not syncing with AirMini | Bluetooth connection interrupted | Keep phone within Bluetooth range of AirMini during sleep; re-pair in app settings if connection lost |
Frequently Asked Questions
Does myAir share my data with my insurance company?
myAir data is shared with your prescribing physician and DME supplier through ResMed's AirView clinical portal — this is standard and expected as part of therapy management. Insurance companies receive compliance reports from your DME supplier (typically usage hours and compliance percentage) to authorize continued equipment coverage, but they do not have direct access to your full myAir dashboard. Review ResMed's privacy policy for the complete data sharing framework if this is a concern.
My myAir score is consistently 95+ but I still feel tired. What's going on?
A high myAir score confirms your CPAP therapy is delivering well — adequate usage, good seal, controlled AHI. Persistent fatigue despite well-controlled therapy has several possible causes: comorbid insomnia disorder (requiring CBT-I treatment independently of CPAP), depression or anxiety, thyroid dysfunction, anemia, or in some cases upper airway resistance syndrome (UARS) producing arousals that aren't captured in AHI. A clinical review is the right next step. Our $49.99 RT Consultation can review your data and help identify whether the explanation is therapy-related or warrants broader medical evaluation.
Can I use myAir with a non-ResMed CPAP machine?
No. myAir is ResMed's proprietary platform and only works with ResMed AirSense and AirCurve devices. Philips Respironics uses the DreamMapper app for its devices; Fisher & Paykel has its own platform. If you have a non-ResMed device, check the manufacturer's website for the compatible patient app.
Does myAir work outside the United States?
myAir is available in most countries where ResMed devices are sold, though the specific features and coaching content may vary by region. Cellular data upload requires compatible cellular network coverage at your device location. When traveling internationally, data upload may be delayed until you return to a compatible network area — for travel CPAP strategies, see our guide on traveling with a CPAP machine.
What's the difference between myAir and AirView?
myAir is the patient-facing app — designed for you to monitor your therapy with a simplified score and visualizations. AirView is the clinician-facing platform — your physician and DME supplier use it to access the same underlying data with additional clinical detail, including flow waveform analysis, leak graphs, and therapy event breakdown. Both pull from the same data source; AirView shows more granular clinical information while myAir presents a patient-friendly summary.
The Bottom Line
myAir turns your CPAP machine from a black box into a transparent therapy tool. The score is useful as a daily habit anchor, but the real value is in the trend data and the correlation work — understanding why your scores vary and using that understanding to optimize the two or three variables that matter most for your therapy.
Check it daily. Review it weekly. Bring it to your appointments. Use it to catch problems before they become patterns. That five-minute investment is what separates patients who stay on therapy with excellent long-term outcomes from those who gradually drift away from it.
