Results
Patients with OSA-I and OSA-II represented 6% (n=84, 71% males) and
10% (n=144, 72% males) of the national cohort, respectively. The
apnea-hypopnea index (63% vs 76%), alone or combined with nocturnal
gas exchange (25% vs 21%, for OSA-II and OSA-I patients respectively)
were used as initiation criteria of CPAP/NIV. OSA-II patients were older
at CPAP/NIV initiation (mean age 11.0±4.0 vs 6.8±4.5 years,
p<0.001) and were treated for a longer time (2.3±2.6 vs
1.3±1.5 years, p=0.008) than OSA-I patients. NIV was used in 6% of
OSA-I patients and 13% of OSA-II patients (p=0.142). Nasal mask was the
most used interface in both groups. Mean CPAP level was higher in OSA-II
patients as compared to OSA-I patients (8.7±2.0 vs 7.7±2.4
cmH2O, p=0.02). Objective compliance was comparable
(mean use 6.8±2.6 vs 5.9±3.0 hours/night in OSA-I and OSA-II,
respectively, p=0.054).
