Trial of Auto Continuous Positive Airway Pressure (CPAP)

Background: In patients with obstructive sleep apnea, automatic continuous positive airway pressure machines (autoCPAP) are said to be capable of identifying various breathing abnormalities during sleep and to correct them by increasing progressively the positive pressure applied to the airway. Once breathing becomes normal, pressure slowly declines. AutoCPAP devices have never been tested in Phase I studies. The investigators hypothesised that normal breathing would not be recognised as such, and that pressure would increase even in a normal subject.

Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Reliability of Automatic CPAP Devices. A Double Blind Dummy Controlled Phase 1 Study

Primary Outcome Measures:
  • number of episodes of increases in applied positive pressure, duration of each episode, and maximal pressure attained [ Time Frame: one night ]

Secondary Outcome Measures:
  • reasons for pressure increase and consequences of the increase on sleep continuity [ Time Frame: one night ]

Enrollment: 1
Study Start Date: August 2009
Study Completion Date: October 2009
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: fixed CPAP
subject will sleep with a fixed CPAP device at minimal pressure
Device: CPAP
CPAP at 4 cm H2O
Experimental: autoCPAP
the subject will sleep connected to an autoCPAP device
Device: autoCPAP
autoCPAP working between 4 and 15 cm H2O

Detailed Description:
Material and Methods: We will submit one normal (confirmed with two polysomnographies, PSG) subject to a double blind study. Pairs of PSG will be performed on successive days once a week, one night with a 4 cm water fixed pressure CPAP device, previously shown not to disturb the subject's sleep and breathing, the other night with one of five well known autoCPAP devices programmed to work between 4 and 15 cm H2O pressure. The same mask and headgear will be used throughout the study. The subject and the physicians reading the tracings will ignore which device is being used on which night.
