Published Results. Proven Reliability.

In a large meta-analysis, WatchPAT™ technology delivered consistently reliable accuracy in study after study vs PSG

Meta-analysis published in JAMA Otolaryngol Head Neck Surg1

  • High combined overall AHI and RDI correlation with PSG: 89%1:
  • High individual correlation with PSG1:
    • AHI: 89%
    • RDI: 88%
    • ODI: 94%
The correlation between PSG and WatchPATTM technology was significant across all measures (P<0.001)1


Strengthened by the blinded design of most of the included studies, this technology represents a viable alternative to PSG for confirmation of clinically suspected sleep apnea.
