Bilevel Positive Airway Pressure-Timed mode is referred to as BiPAP T. BiPAP T administers breaths at a set rate whether or whether the patient initiates breathing, in contrast to BiPAP S (Spontaneous), which only helps when the patient does so.

Patients with central sleep apnea, neuromuscular disorders, stroke, or advanced respiratory failure who have little to no spontaneous breathing effort are treated in this mode.
