How does the BiPAP mode function in non-invasive ventilation?

• A. It uses a single level of pressure
• B. It delivers one level of pressure during inhalation only
• C. It delivers two levels of pressure: higher inspiratory and lower expiratory
• D. It provides continuous pressure throughout the breathing cycle

Answer: (C)

The BiPAP mode, or Bilevel Positive Airway Pressure, functions by delivering two distinct levels of pressure throughout the breathing cycle, which is essential in non-invasive ventilation. This dual pressure approach includes a higher pressure level during inhalation, known as the inspiratory positive airway pressure (IPAP), which facilitates adequate ventilation by promoting alveolar recruitment and improving gas exchange. During exhalation, a lower pressure level, referred to as expiratory positive airway pressure (EPAP), is applied to help maintain airway patency and enhance comfort. By utilizing both inspiratory and expiratory pressure, BiPAP effectively addresses issues such as obstructive sleep apnea or respiratory failure by optimizing the work of breathing and improving oxygenation without the need for invasive intubation. This mode's capability to provide comfortable and variable pressures makes it particularly advantageous for patients with fluctuating respiratory demands.
