Validity of a Supersimplified Device for Diagnosis of Patients With Suspected Obstructive Sleep Apnoea-hypopnoea (OSAH)
This trial is active, not recruiting.
|Condition||obstructive sleep apnea|
|Treatments||psg, micromesam system|
|Sponsor||Basque Health Service|
|Start date||March 2009|
|End date||December 2013|
|Trial size||815 participants|
|Trial identifier||NCT01347398, ApneaLink|
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.
|Intervention model||crossover assignment|
Sleep study made by MicroMESAM system
Sleep study made by PSG (polysomnography)
Number of patients correctly diagnosed by MicroMESAM (APNEA-LINK)
time frame: 3 months
Male or female participants from 18 years up to 75 years old.
- Patients 18 to 75 years of both sexes.
- 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.
- Informed consent signed by the patient.
- Place of residence more than 100 km from the hospital.
- inability to perform psychophysical study at home.
- 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.
- Patients with chronic insomnia or recognize sleep less than six hours.
- Patients with depression (both point 4 and 5 are the potential causes of false negatives in a PR for lack of sufficient sleep time).
- nasal obstruction complete or nearly complete, which prevents obtaining a quality signal with MicroMESAM
