What is a key difference between CPAP and BiPAP airflow?
CPAP is designed for more complex sleep and breathing disorders.

CPAP delivers two different pressure settings for inhalation and exhalation.
BIPAP delivers a constant set pressure during inhalation and pressure relief during exhalation.
The Correct Answer is B
A. CPAP is typically used for simpler obstructive sleep apnea, while BiPAP is often used for more complex cases.
B. BiPAP delivers two different pressure levels: a higher pressure during inhalation (IPAP) and a lower pressure during exhalation (EPAP), which helps patients breathe more easily.
