In a clinical study comparing OSA patients with and without insomnia,2 those with insomnia had:
Many patients may not adequately report their insomnia symptoms—or even mention them at all4
Because of night-to-night variability, a single overnight test can lead to an inaccurate diagnosis
Factors contributing to night-to-night variability may include:
Instant, comprehensive results can mean a faster diagnosis—and a faster path to personalized treatment
Immediate results may help avoid delays due to backlogs, slow shipments, or a patient’s inability to promptly return an HSAT
In a clinical study,7 patients with severe sleep-disordered breathing were more adherent when wait times to treatment were shorter
The same study also found that earlier treatment initiation resulted in7:
