Bi-Level is another form of non-invasive positive pressure ventilation (NPPV) using two pressure levels: inspiratory positive airway pressure (IPAP) and an expiratory positive airway pressure (EPAP). Inspiration is commonly patient triggered but can also be time triggered.

Bi-Level is not the same as continuous positive airway pressure (CPAP).

Bi-Level is typically indicated for a more clinically complex and compromised set of patients and should only be initiated and monitored by highly skilled, experienced and appropriately qualified personnel.

The Respiratory & Sleep Medicine Practice uses the latest state of the art Bi-Level equipment for pressure titrations. A full Polysomnogram (PSG) similar to that used during a diagnostic sleep study is also used during a Bi-Level titration study. We perform only manual in-lab Bi-Level titration studies under the direct supervision of our Respiratory & Sleep Physician and Clinical Sleep Physiologist.
