Final answer:
The difference between BiPAP and CPAP involves the air pressure delivery; CPAP provides constant air pressure, while BiPAP offers two levels, one for inhalation and a lower one for exhalation, which can be more comfortable for patients requiring higher pressures or having central sleep apnea.
Step-by-step explanation:
The difference between BiPAP and CPAP primarily lies in the air pressure delivery during treatment for sleep apnea. A CPAP (Continuous Positive Airway Pressure) machine delivers a constant and steady air pressure, which is similar to the air pressure level when a person inhales. In contrast, a BiPAP (Bilevel Positive Airway Pressure) provides two different levels of air pressure: a higher pressure when the user inhales and a lower pressure when the user exhales. This can be more comfortable for some individuals, particularly those with higher pressure settings or those with difficulty exhaling against CPAP pressure. CPAP is typically recommended for patients with obstructive sleep apnea, where the airway collapses or becomes blocked during sleep. BiPAP may be used for patients with central sleep apnea, where the issue is related to the brain's signals to the muscles that control breathing, or for those who require additional respiratory support due to other medical conditions.
