Brief Summary:
The diagnosis of OSASH requires expensive sleep tests that generate long waiting lists, so we need simplified and rapid diagnostic tools. The ApneaLinkTM, is a device that allows the assessment of respiratory events by measuring the flow ventilation with a nasal cannula connected to a pressure transducer.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients 18 to 75 years of both sexes.
  2. clinical suspicion of OSAH defined as subjects with breathing pauses during sleep and / or asphyxiated sounds, with or without excessive daytime sleepiness as measured by the Epworth scale and who have asked for a sleep test to rule out OSAH.
  3. Informed consent signed by the patient.

Exclusion Criteria:

  1. Place of residence more than 100 km from the hospital.
  2. inability to perform psychophysical study at home.
  3. cardio-vascular disease, cerebro-vascular or respiratory or acute severe unstable as to preclude the proper conduct of studies at home and / or PSG in the laboratory.
  4. Patients with chronic insomnia or recognize sleep less than six hours.
  5. Patients with depression (both point 4 and 5 are the potential causes of false negatives in a PR for lack of sufficient sleep time).
  6. nasal obstruction complete or nearly complete, which prevents obtaining a quality signal with MicroMESAM
