In CPAP mode, what is primarily set by the clinician?

In CPAP (Continuous Positive Airway Pressure) mode, the primary setting that is determined by the clinician is the continuous pressure. CPAP provides a constant level of pressure throughout the respiratory cycle, which helps to keep the airways open and improve oxygenation in patients, especially those with conditions like obstructive sleep apnea or respiratory distress.

Unlike modes that require the clinician to set tidal volume, respiratory rate, or inspiratory time—which are associated with more invasive forms of ventilation—CPAP is designed to maintain a steady pressure without the necessity for these additional parameters. This focus on maintaining continuous pressure aids in preventing airway collapse during both inhalation and exhalation, thus ensuring a stable breathing pattern for the patient.

Understanding this core principle of CPAP is crucial for effective patient management, particularly in noninvasive ventilation settings where less invasive intervention is preferred.
