Impact of Mask Type on the Effectiveness of and Adherence to Unattended Home-Based CPAP Titration

الملخص EN

Objectives.

To compare interfaces performance during home-based automatic titration (APAP).

Methods.

Retrospective study based on APAP titration from Obstructive Sleep Apnea Syndrome (OSA) patients.

Results.

707 patients, 513 men (70.6%), were titrated.

Masks were 104 pillows (14.7%), group I (GI); 532 nasal (75.2%), group II (GII); and 71 oronasal masks (10%), group III (GIII).

We found differences in effective pressure to the device (P90/P95) (GI: 7.13±1.9 vs.

GII: 8.3±2.1 vs.

GIII: 9.3±2.6 cmH2O, p <0.001) but not in final pressure titrated manually (GI: 7.9±1.4 vs.

GII: 8.6±1.6 vs.

GIII: 9.2±1.9 cm of H2O, p >0.5), where lower residual AHI for pillows was p <0.001 and leaks for nasal were p <0.001.

No differences were found in compliance (hours) (GI: 6.3±1.2 vs.

GII: 6.2±1.1 vs.

GIII: 6.1±1.0, p <0.4).

Conclusion.

During auto-adjusting titration by CPAP-naïve patients, nasal masks had lower leak rates and nasal pillows presented a similar performance.
