WatchPAT

The PAT® Signal

PAT signal upstroke variations reflect changes in intra-thoracic  pressure (ITP) that are influenced by the status of respiration.  ITP changes are diminished during central events as there is no respiratory effort, relatively stable during normal respiration and increase during Obstructive Sleep Apnea events.





OSA WatchPAT

Obstructive Sleep Apnea (OSA) is a common  chronic disorder that often requires lifelong care. This occurs when  the muscles in the back of the throat fail to keep the airway open  during sleep. A person may experiences apneas, hypopneas and flow  limitation- repetitive episodes of obstruction of the upper airway  during sleep. 

 

  • Apnea: a cessation of airflow for ≥ 10 seconds
  • Hypopnea: a decrease in airflow lasting ≥ 10 seconds with a 30%  oxygen reduction in airflow and with at least a 4% oxygen desaturation  from baseline
  • Flow limitation: narrowing of the upper airway and an indication of an impending upper airway closure

The prevalence of any OSA is estimated to be 33.9% in men and 17.4% in women – 25% on average

  • 1 in 5 adults has mild OSA
  • 75% of severe SDB cases remain undiagnosed
