What is Bi-Level Ventilation?

Bi-level ventilation with the Harmony S/T Ventilatory
Support System helps you to breathe by supplying two
levels of air pressure. The Harmony S/T provides a higher
pressure—known as IPAP (Inspiratory Positive Airway
Pressure)—when you inhale, and a lower pressure—
known as EPAP (Expiratory Positive Airway Pressure)—
when you exhale. The higher pressure opens your airway
to increase the amount of air going into your lungs, and the
lower pressure makes it easier for you to exhale while still
keeping your airway open.
