CPAP Pressure Range & Mask Fit Budget Calculator

Blend your prescribed pressure, current AHI, nightly usage, and mask replacement cadence to size an auto-adjusting pressure window and a monthly supply budget that supports comfort and insurance compliance.

Use your titrated fixed pressure or the median pressure reported by your auto-CPAP.
Latest AHI from your diagnostic study or compliance download.
Average hours per night you stay on therapy across a typical week.
Typical replacement cadence for cushions or full masks in days.
Defaults to $45 if blank. Enter the retail cost of the mask or cushion kit you replace at this cadence.

Not a medical device. Confirm pressure and equipment decisions with your clinician before making changes.

Examples

  • 11 cmH₂O prescription, AHI 22, 6 hours/night, 90-day mask interval at $48 ⇒ range 8.4–13.6 cmH₂O (±2.6), $16.23/month mask spend, 85.7% compliance
  • 9 cmH₂O prescription, AHI 12, 3.5 hours/night, 60-day interval with default cost ⇒ range 7.5–11.3 cmH₂O (±1.5), $22.83/month supplies, 50.0% compliance

FAQ

Does this replace a titration study?

No. Use the output to discuss adjustments with your sleep specialist—it reflects guideline ranges, not medical orders.

How should I handle altitude or humidifier changes?

Enter baseline values and share the recommended range with your provider. They may nudge the upper limit when you add humidification or sleep at altitude.

Can I model mask wipes or tubing replacements?

Add their cost to the optional mask kit field after spreading bundles across the cadence you follow so the monthly spend captures every consumable.

What if my compliance score is low?

Use ramp features, mask refits, or positional therapy to extend nightly hours—crossing the four-hour mark on most nights keeps you inside CMS rules.

Can I estimate supply costs if my DME provides bundles?

Yes. Divide the bundle price by the number of usable masks or cushions and enter that per-unit number so the calculator allocates spend accurately.

Additional Information

  • Auto-CPAP algorithms typically hold pressures within ±5 cmH₂O of the titrated value; this model scales the buffer between 1.5 and 5 cmH₂O using your AHI.
  • Usage below four hours per night triggers CMS non-compliance—push nightly time upward to protect reimbursement.
  • Divide bundle pricing by the number of cushions or masks in the pack before entering the optional cost so the budget reflects per-unit spend.
  • The monthly budget multiplies your cost by 30.44 days (average month) divided by the interval you supplied.
  • Compliance is benchmarked against seven hours of availability per night, mirroring many insurer scorecards.
