title: [A population study of the efficacy of pulsioxymetry in diagnosing obstructive sleep apnoea syndrome].
abstract: OBJECTIVE
  To evaluate the use at home of night-time pulsioxymetry to diagnose obstructive sleep apnoea syndrome in the general population.
  
  
  METHODS
  Cros-sectional study of diagnostic tests.
  
  
  METHODS
  Random sample of 70 individuals chosen from a Health Centre´s appointment records.
  
  
  METHODS
  Anamnesis concerning sleep and respiratory disorders during sleep, anthropometric measurements, Epworth´s sleepiness scale, home night-time pulsioxymetry and polysomnography.
  
  
  RESULTS
  Visual inspection by oxymetry gave 82% sensitivity (95% CI, 62-93) and 69% specificity (95% CI, 53-82) for the diagnosis of obstructive sleep apnoea syndrome. Other indices such as the time with oxygen saturation below 90% and the number of desaturations above 4% gave a sensitivity of 82% and 86% and specificity of 63% and 65%, respectively. All the cases of clinically significant obstructive apnoea were diagnosed by pulsioxymetry.
  
  
  CONCLUSIONS
  Night-time pulsioxymetry is a useful test for general screening of obstructive sleep apnoea.
