What does CPAP stand for?

CPAP stands for Continuous Positive Airway Pressure. This term refers to a medical device or treatment method commonly used in respiratory therapy, particularly for patients with conditions such as obstructive sleep apnea, chronic obstructive pulmonary disease (COPD), and other respiratory insufficiencies.

The primary function of CPAP is to maintain a continuous level of positive pressure in the airways, preventing airway collapse during inhalation, which helps to keep the air passages open and improve oxygenation. By delivering a steady flow of air, CPAP can significantly enhance a patient's ability to breathe and ensure adequate ventilation, reducing the risk of associated complications that can arise from airway obstruction.

The other options do not accurately represent the established terminology or function related to CPAP. They either introduce incorrect terminology or mischaracterize the fundamental function of the device. Understanding this terminology is crucial for effectively recognizing and communicating about respiratory therapies in clinical settings.
