Pourquoi faire une polygraphie cardio respiratoire du sommeil (PCRS) de type PAT?

Why do a cardiorespiratory sleep polygraphy (CRSP) type PAT?

ASC Clinic uses the WatchPAT®️ONE system to perform PCRS testing. Only the WatchPAT®️ONE system uses the PAT (Peripheral Arterial Tone) signal. The device does not need to be returned to your clinic. The data is captured and sent to the cloud with a free cellular application.

Monitoring peripheral arterial tone (PAT) during a home sleep test is important for several reasons:

  1. Accurate detection of sleep apnea: PAT technology, used in devices such as WatchPAT®️ONE, measures changes in the volume of the arterial pulse at the finger, which can indicate apneas (breathing pauses) and hypopneas (shallow breathing) during sleep. This helps diagnose conditions such as obstructive sleep apnea (OSA). The PAT signal also helps determine whether you are awake, in REM or non-REM sleep, unlike traditional PCRS. The PCRS PAT result is therefore more accurate than traditional PCRS.
  1. Non-invasive and convenient: PAT-based home sleep tests are non-invasive and can be performed in the comfort of your own home. This makes it easier for patients to undergo testing without having to spend the night in a sleep lab.
  1. Up to 90% correlation with polysomnography (PSG): Although in-lab polysomnography (PSG) is the gold standard for diagnosing sleep disorders, PAT-based home sleep tests have shown good agreement with PSG, especially in moderate to severe cases of OSA. Therefore, they can be a reliable alternative for many patients. Cases demonstrating mild OSA or no OSA but with individuals exhibiting many symptoms may require PSG in the lab (PSG N1) or in the comfort of your home (PSG N2).
  1. Comprehensive Data Collection: PAT devices not only measure arterial tone, but also monitor pulse, oxygen saturation (blood oxygen level), snoring, chest movement, body activity and chest movements. This comprehensive data allows for highly accurate diagnosis of sleep apnea and assessment of its severity.

5.The American Academy of Sleep Medicine (AASM) has recognized PAT technology as a technically adequate method for home sleep testing. The AASM guidelines are also followed in sleep medicine in Canada.
