How to Use This Calculator
- Enter the patient's BMI in kg/m².
- Input the Apnea-Hypopnea Index (AHI) from the diagnostic polysomnography report.
- Enter neck circumference in cm and supine AHI if available.
- Review the estimated starting CPAP pressure range.
- Titrate final CPAP pressure through an attended titration study or auto-CPAP data.
