title: [Ambulatory measuraments are better tolerated than in-hospital measuraments of sleep apnea.].
abstract: OBJECTIVE
  This study compares self reported measures of sleep quality between groups of patients undergoing ambulatory or in-hospital annual control of Continuous Positive Airway Pressure (CPAP) therapy.
  
  
  METHODS
  70 consecutive Obstructive Sleep Apnea Syndrome (OSAS) patients scheduled for an annual control of CPAP therapy were randomly assigned to either ambulatory or in the hospital conditions. The same recording equipment was used in both conditions.
  
  
  RESULTS
  Overall the ambulatory group slept better, had less difficulties falling asleep, and was less anxious about the study than the in-hospital group.
  
  
  CONCLUSIONS
  The results provide one reason for regarding ambulatory recordings more favourably than similar registration done in-hospital.
