What is the primary goal of using BiPAP in patients?

The primary goal of using BiPAP (Bilevel Positive Airway Pressure) in patients is to abolish hypopnea and improve gas exchange. BiPAP functions by delivering two levels of positive airway pressure: a higher pressure during inhalation and a lower pressure during exhalation. This mechanism effectively aids in the recruitment of collapsed alveoli, which enhances ventilation and improves oxygenation.

By alleviating hypopnea, which is characterized by shallow or slow breathing, BiPAP helps ensure that patients take deeper breaths, thereby facilitating better gas exchange. This is particularly crucial in conditions like chronic obstructive pulmonary disease (COPD) and acute respiratory distress, where gas exchange is compromised.

While aspects like reducing the workload of breathing and potentially increasing lung compliance are benefits of BiPAP, the direct aim is to enhance breathing patterns and improve overall gas exchange in patients who struggle with respiratory insufficiency.
