In a CPAP machine, how is the pressure managed during use?

In a CPAP machine, the pressure is designed to remain constant during both inhalation and exhalation. This constant positive airway pressure helps keep the airways open, thereby preventing obstruction and facilitating unobstructed breathing. The consistent delivery of air pressure assists patients with conditions like obstructive sleep apnea, improving their overall respiratory function during sleep.

The principle behind CPAP is to provide a steady flow of air to ensure that the airway does not collapse, which can occur during sleep when the muscles relax. The unchanging pressure allows users to breathe normally while ensuring that the upper airway remains patent, regardless of whether they are inhaling or exhaling. Thus, the machine works effectively to maintain adequate oxygenation and reduce the risk of apnea events.

Understanding the function of CPAP is crucial for both healthcare providers and patients, as it underscores the importance of smooth, constant airflow throughout the breathing cycle.
