What are the two levels of pressure used on a BiPAP device?

The correct answer is IPAP and EPAP. In a BiPAP (Bilevel Positive Airway Pressure) device, there are two distinct levels of pressure that serve specific functions during mechanical ventilation.

IPAP, or Inspiratory Positive Airway Pressure, is the higher pressure level that is delivered during inhalation to assist patients in drawing air into their lungs. This pressure helps facilitate gas exchange and reduce the work of breathing, particularly in patients who may struggle with their respiratory effort.

EPAP, or Expiratory Positive Airway Pressure, is the lower pressure level that maintains airways open during exhalation. This prevents airway collapse and promotes oxygenation by ensuring that the lungs remain partially inflated, thus improving ventilation.

Understanding these two levels is crucial for effectively using BiPAP therapy, as it allows healthcare providers to tailor the pressure settings based on the specific respiratory needs of the patient.
