Outcome Measures
Primary Outcomes (1)
Flow limitation
Flow limitation in percentage of total sleep time. The flow limitation will be assessed by the flow curve obtained in the polysomnographic recording.
4 weeks after each CPAP modality completion
Secondary Outcomes (3)
Adherence to CPAP treatment
4 weeks after each CPAP modality completion
Arousal index
4 weeks after each CPAP modality completion
Wake time after sleep onset
4 weeks after each CPAP modality completion
Study Arms (3)
CPAP C- Flex-Plus by Philips Respironics
EXPERIMENTALFour consecutive weeks with CPAP C- FLEX PLUS treatment. After these 4 weeks, patients will undergo full PSG with CPAP FLEX- PLUS. Patients will also fill out Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Functional Outcome Sleep Questionnaire, and visual analogue scale assessing CPAP side effects and patient´s comfort. Adherence to 4-week treatment will be checked. Treatment is followed by 7-day washout period.
CPAP with Sensawake by Fisher and Paykel
EXPERIMENTALFour consecutive weeks with CPAP Sensawake treatment. After these 4 weeks, patients will undergo full PSG with the same CPAP modality. Patients will also fill out Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Functional Outcome Sleep Questionnaire, and visual analogue scale assessing CPAP side effects and patient´s comfort. Adherence to 4-week treatment will be checked. Treatment is followed by 7-day washout period.
CPAP fixed pressure
ACTIVE COMPARATORFour consecutive weeks with CPAP fixed pressure treatment. After these 4 weeks, patients will undergo full PSG with the same CPAP modality. Patients will also fill out Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Functional Outcome Sleep Questionnaire, and visual analogue scale assessing CPAP side effects and patient´s comfort. Adherence to 4-week treatment will be checked. Treatment is followed by 7-day washout period.
Interventions
Continuous positive airway pressure (CPAP) is the gold standard treatment for moderate and severe OSA, and it has been known to apply positive pressure in the upper airways, acting as a pneumatic splint preventing the upper airway collapse during sleep. CPAP C- Flex Plus by Philips - Respironics works just as CPAP Fixed Pressure, but increases the pressure delivered in the begining of inhalation to softens the breathing rhythm of the CPAP user. CPAP with SensAwake by Fisher and Paykel works just as CPAP fixed pressure but when the breathing pattern suggests that patient is awake, a prompt relief in pressure to the lowest most comfortable level is activated, like ramp feature.

- PARTICIPANT, INVESTIGATOR
- Masking Details
- Participants have never had contact with CPAP, therefore were not aware of PAP modality prescribed. Investigator were also naive, as well as sleep specialist responsible for Polysomnography reports. Only respiratory therapist who was assigned to CPAP clinic was aware of patient´s treatment condition.
