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
