Characteristics of the patients and ventilator settings in cases reported
| Case | Diagnosis | BMI (kg/m2) | VC (%) | Baseline AHI | Baseline PaCO2/PaO2 (mm Hg) | IPAP/EPAP (cm H2O) | Rise time (ms) | TiMIN/TiMAX (ms) | Backup RR (/mn) |
|---|---|---|---|---|---|---|---|---|---|
| 1 | OHS | 57 | 69 | 117 | 57/61 | 22/14 | 400 | 0.8/1.8 | 12 |
| 2 | OHS | 35 | 83 | 35 | 53/71 | 27/15 | 200 | 0,8/1.8 | 14 |
| 3 | NMD | 37 | 54 | 22 | 48/82 | 18/8 | 200 | 0.8/1.8 | 14 |
All used a Stellar 100 ventilator (Resmed, Australia).
AHI, apnoea/hypopnoea index; BMI, body mass index; EPAP, expiratory positive airway pressure; IPAP, inspiratory positive airway pressure; NMD, neuromuscular disease; OHS, obesity hypoventilation syndrome; PaCO2 and PaO2, blood arterial pressure in CO2 and O2; RR, back-up respiratory rate; TIMAX, maximal inspiratory time; TIMIN, minimal inspiratory time; VC, vital capacity (in % of predicted).
