FAQs: 

Who needs BiPAP with oxygen support?
BiPAP with oxygen is often prescribed for people with COPD, congestive heart failure, sleep apnea with low oxygen levels, neuromuscular disorders, or chronic respiratory failure who need both pressure support and additional oxygen.

What is the difference between a BiPAP and CPAP machine?
The main difference is pressure delivery. A CPAP machine provides a single, continuous air pressure, while a BiPAP machine delivers two pressures—one for inhaling and one for exhaling. BiPAP is usually recommended for patients who struggle to exhale against CPAP pressure or need advanced breathing support.

BiPAP vs CPAP: which one is better?
Neither is universally better—it depends on the patient’s condition. CPAP machines are typically used for mild to moderate obstructive sleep apnea, while BiPAP machines are better for complex sleep apnea, COPD, or conditions requiring variable pressure levels and oxygen support.
