Research collaboration

AirwayLab is building one of the largest PAP therapy datasets for sleep science. Contributed metrics, waveforms, and traces carry no name or email and are stored under a random contribution ID together with the therapy night’s date, internally linked to your account while it exists and permanently unlinkable after account deletion. If you separately opt in to raw device file contribution, those files are stored linked to your account and deleted when you withdraw consent. Data is stored in the EU. We believe better data leads to better therapy — and we work with researchers on a partnership basis to advance the field.

Consent-based · No name or email · EU-hosted · Open-source engine

What's in the dataset

Glasgow Index

Overall score (0–9)
9 component scores: skew, spike, flat top, top heavy, multi-peak, no pause, inspiratory rate, multi-breath, variable amplitude
Per-session and duration-weighted nightly averages

WAT (Wobble Analysis Tool)

FL Score: relative inspiratory flatness index (not a percentage)
Regularity: Sample Entropy on minute ventilation
Periodicity Index: FFT power in 0.01–0.03 Hz band

NED Analysis

NED mean, Flatness Index, Tpeak/Ti ratio
M-shape detection percentage
RERA events per hour, Estimated Arousal Index
Combined FL percentage, H1/H2 split comparisons

Oximetry (optional)

ODI-3% and ODI-4% (desaturation indices)
Heart rate surge counts at multiple thresholds
Coupled cardio-respiratory events
Desaturation time, SpO₂ summary statistics

All metrics are computed from ResMed SD card flow waveform data. Raw waveforms are available for a subset of contributors who explicitly opted in to waveform sharing. Machine settings metadata (device model, pressure settings, mode) is included where available.

How data is collected

Browser-only analysis

A PAP user uploads their SD card data. All analysis runs in their browser — nothing is sent to a server.

Voluntary opt-in

After seeing their results, the user can choose to contribute metrics that carry no name or email. This is always opt-in, never automatic.

Stripping identifiers

For metric and waveform contributions, names, emails, and device serial numbers are stripped in your browser. Contributions are stored under a random contribution ID together with the date of the therapy night, plus aggregate breathing metrics and machine settings.

Secure EU storage

Data is stored in an EU-hosted database with row-level security. For metric and waveform contributions, identifier stripping happens in your browser before anything is sent.

How to collaborate

We're looking for researchers and clinicians who want to use real-world PAP therapy data to advance sleep science. Here's what we can offer:

Access to aggregate breathing metrics that carry no name or email, from thousands of real-world therapy nights
Validation partnerships for our analysis engines (Glasgow Index, WAT, NED) against clinical gold-standard measurements
Joint research on flow limitation patterns, effort-pattern analysis, and the relationship between breathing metrics and patient outcomes
Open-source analysis engine (GPL-3.0) — adapt our algorithms for your research, contribute improvements back

Data privacy and ethics

AirwayLab handles health data. We take that seriously.

GDPR-compliant. All data stored in the EU (Supabase, eu-west region).
Every contribution requires explicit, informed consent. No silent collection, no pre-checked boxes.
For metric and waveform contributions, identifier stripping runs in your browser before anything is sent — inspect the network requests yourself.
Raw device files you contribute can be deleted at any time by withdrawing consent. Metric, waveform, and trace contributions are retained for research, permanently unlinked from your account after account deletion.
