AI sleep analysis
Ask about your night. Luna explains your CPAP and wearable data, bringing relevant charts and event flags directly into the conversation.
For adults using prescribed PAP therapy. Built to help you understand your sleep data.
The pattern to explore is a late-night rise in leak. The nightly event rate gives an overview; the signals and individual flags show what happened in more detail.
Main takeaways01 / Patterns
Can you show me how leak and pressure changed through the night?
Leak stays low early in this sample night, then rises around 4:52–5:53 AM, peaking near 15.8 L/min. Pressure also changes across the night. I’ve brought both charts into our conversation so you can compare their timing with the event flags.
Recorded Luna response, edited for clarity. Synthetic data; not medical advice.
01 / Guided by Luna AI
Follow a finding from the nightly summary to the signal behind it. Keep asking until the data makes sense to you.
Review
Start with your recorded breathing events, mask leak, pressure and available sleep measures. Luna explains what stands out.
Ask
Ask to see a signal or inspect a flag. Luna brings the relevant chart into the conversation alongside its explanation.
Compare
Compare saved reviews to see whether a change appears across several nights or in just one.
Understand
Add how you felt or what you remember. Luna connects your observations to the available data and suggests a useful next question.
PAP data comes from supported card files. Optional Apple Watch and Oura Ring data connects through Apple Health on iPhone.
02 / Sleep health
Sleep supports memory, mood and physical health. Duration, regularity and quality all matter.
Duration / 01
Adults aged 18–60 generally need at least seven hours a night. Needs vary with age and individual circumstances.
CDC / Sleep durationRhythm / 02
Your circadian system helps time sleep and wakefulness. Consistent bedtimes and wake times support that rhythm.
NHLBI / Healthy sleepArchitecture / 03
Sleep cycles through non-REM and REM stages. Repeated disruption can leave you unrefreshed, even after enough time in bed.
NHLBI / Sleep stages03 / Sleep apnea
Obstructive sleep apnea occurs when the upper airway repeatedly narrows or closes during sleep. These interruptions can fragment sleep and lower blood oxygen.
Untreated sleep apnea is linked to cardiovascular and metabolic health problems. Diagnosis and follow-up are essential to care.
Read the NHLBI overviewLoud snoring, witnessed breathing pauses, gasping and daytime sleepiness can be signs of sleep apnea.
Symptoms alone cannot establish a diagnosis. A clinician evaluates your history and may arrange a sleep study.
Positive airway pressure (PAP), including CPAP, uses pressurized air to help keep the upper airway open during sleep.
Discuss persistent symptoms, mask discomfort and changes in therapy data with your care team. Treatment needs individual follow-up.
04 / Reading the evidence
Luna separates what was recorded, what it may mean and what the data cannot establish.
| Signal | What it shows | What to keep in mind |
|---|---|---|
| AHI | Machine-estimated apneas and hypopneas per therapy hour. | A therapy estimate; not the same measurement as a diagnostic sleep-study AHI. |
| Leak | Air escaping from the mask or circuit, as reported by the device. | Definitions vary by manufacturer. Large leaks can affect therapy and event estimates. |
| Usage & pressure | Recorded therapy time and the pressure delivered. | Usage is not sleep duration. Pressure alone does not show whether treatment is effective. |
| Sleep & oxygen | Available wearable estimates of sleep stages and oxygen samples. | Coverage and accuracy vary. Consumer estimates do not replace a clinical sleep study. |

05 / Data & privacy
Original PAP files stay on your iPhone. With your consent, selected summaries and short signal windows may be sent for cloud AI analysis.
Reviews, conversations and voice transcripts are saved in your account.
06 / Common questions
Try “Show me the airflow around this flag” or “Did this pattern appear on another night?” Luna uses your available data to explain the finding and bring relevant visuals into chat.
No. Snoring alone does not establish sleep apnea. Breathing pauses, gasping or persistent daytime sleepiness warrant a conversation with a clinician. Learn about symptoms.
A clinician considers your symptoms and health history, then may recommend an overnight laboratory study or a home sleep apnea test, depending on your circumstances. Luna does not diagnose sleep apnea. Learn about diagnosis.
No. Luna explains therapy data; it does not control your machine or prescribe treatment. Discuss setting changes with your care team.
Wearables offer estimates of sleep timing, stages and heart rate. Luna labels each source and keeps these estimates separate from PAP observations. They do not replace clinical assessment.
Luna reviews the signals available and identifies coverage gaps. Missing waveform or event detail is not filled in.
No. It uses synthetic sleep data and recorded Luna responses, edited for clarity. Explore the charts and event analyses here; use Luna for a live conversation about your own data.
