The Tranquility Bilevel is specifically designed to cater to the special needs of adult patients with Obstructive Sleep Apnea (OSA) who are not properly responding to continuous positive airway pressure therapy. Delivers two different pressure levels, IPAP and EPAP, for more comfortable therapy. The unit features a Compliance Monitor that records when the unit is on or off and when the user is actually breathing on the device. A three-position adjustable RiseTime control can be adjusted to match the patient’s natural breathing rhythms which can help increase comfort and compliance.
