What is the primary function of Continuous Positive Airway Pressure (CPAP)?

The primary function of Continuous Positive Airway Pressure (CPAP) is to maintain mild air pressure to keep the airway open. This is particularly beneficial for patients experiencing conditions like sleep apnea or certain respiratory distress situations, as the constant pressure helps prevent the collapse of the airways during inhalation and exhalation. By keeping the airways open, CPAP facilitates improved oxygenation and alleviates the work of breathing, allowing for better gas exchange in the lungs.

Maintaining open airways is crucial in various clinical settings, as it directly impacts the patient's ability to breathe effectively without the need for invasive measures. The use of CPAP is typically non-invasive, making it a preferred first-line treatment option in many cases of respiratory failure where airway patency is compromised.
