CPAP Pressure Ramp Compliance Benefit

See how ramp time, nightly use, and leak combine to determine therapeutic hours above 4-night compliance thresholds for insurers.

Pressure prescribed by your sleep specialist at full therapy strength.
Minutes your machine takes to climb from start pressure to prescribed pressure.
Total clock hours you wear the mask each night including ramp time.
Mask leak percentage from your CPAP download; enter 0 if unknown.

Not medical advice. Consult your sleep physician for treatment decisions.

Examples

  • Pressure 12 cmH₂O, 30-minute ramp, 5.5 hours/night, 15% leak ⇒ Effective therapy 4.25 h/night; compliance 100.00%.
  • Pressure 9 cmH₂O, 15-minute ramp, 6.8 hours/night, 8% leak ⇒ Effective therapy 6.03 h/night; compliance 100.00%.

FAQ

Does a longer ramp hurt compliance?

Long ramp times delay reaching therapeutic pressure, so the calculator subtracts ramp minutes from nightly usage before scoring compliance.

How should I estimate leak percentage?

Use the leak metric from your CPAP app or download; if unavailable, start with 10% and refine after your next compliance report.

Can this replace clinical titration advice?

No — it is an educational tool to visualize ramp trade-offs. Always adjust settings with guidance from your sleep specialist.

What if my compliance percentage is below 100%?

The result highlights the nightly shortfall in hours; reduce ramp time, improve mask fit, or extend nightly use to close the gap before insurer audits.

Additional Information

  • Compliance is benchmarked against the common requirement of 4 hours per night on at least 70% of nights within a rolling 30-day window.
  • Leak percentage reflects average mask leak reported by your device; use recent compliance downloads for the most accurate number.
  • Ramp minutes are converted to hours, subtracted, and the remainder is derated for leak to approximate true therapeutic exposure.
  • Delivered pressure reflects prescribed pressure multiplied by (1 − leak%).
