Sleep Findings
Polysomnography (PSG) was performed during the 24-hour HEMII-pH period.
Patients were invited to fulfill the French version of Epworth
Slippiness Scale (ESS)11 and the Pichot fatigue
scale.12 Regarding the PSG data, the following data
were extracted by a board-certified sleep physician (GA) using the
Cidelec v2.2.6. software (Cidelec, Loire, France): Apnea-Hypopnea Index
(AHI); total number of arousals; number of arousals/hour; % of time
with O2 saturation level<90%; and the 4 sleep
phases including the paradoxical sleep. OSAS status was retrieved from
the home sleep study findings considering an AHI≥ 5 per hour as a
positive OSAS diagnosis. OSAS severity was scored according to the
report of the American Academy of Sleep Medicine based on the patient’s
AHI: mild (5-14 events/hour); moderate (15-30 events/hour); or severe
(>30 events/hour).13 Patients with
AHI<5 were excluded.
