How does CPAP differ from BiPAP in terms of pressure delivery?

CPAP, or Continuous Positive Airway Pressure, operates by providing a steady and consistent level of pressure throughout the entire breathing cycle, both during inhalation and exhalation. This continuous airflow helps to keep the airways open, which is particularly beneficial for individuals with sleep apnea and certain other respiratory conditions.

This contrasts with BiPAP, or Bilevel Positive Airway Pressure, which delivers two different settings: one for inhalation and a lower one for exhalation. This variability in pressure can make it easier for some patients to breathe, especially if their condition requires more assistance during inhalation.

Understanding the consistent delivery of pressure in CPAP helps clarify its specific role and advantages in treating patients. It is important to note how this differs fundamentally from BiPAP's dual-pressure system.
