What is the primary purpose of a CPAP machine?

The primary purpose of a CPAP (Continuous Positive Airway Pressure) machine is to maintain an open airway during sleep. This device is specifically designed to treat obstructive sleep apnea (OSA), a condition where the airway becomes blocked or collapses during sleep, leading to interruptions in breathing. By delivering a continuous stream of air, the CPAP machine helps keep the airway open, preventing these episodes of airway blockage and allowing for normal, uninterrupted breathing throughout the night.

The other options do not accurately represent the function of a CPAP machine. While oxygen delivery may be a part of some respiratory therapies, it is not the main function of a CPAP, as it does not primarily deliver supplemental oxygen. Instead, it provides a steady airflow that helps prevent airway collapse. Similarly, monitoring sleep patterns is typically associated with polysomnography or other sleep study equipment, rather than with the CPAP machine itself. Improving mental focus is not a function of a CPAP, although better sleep facilitated by its use can lead to enhanced cognitive function over time. Understanding the primary role of the CPAP in treating sleep apnea highlights its importance in ensuring safe and effective sleep for those affected by this condition.
