Replacement frequency of continuous positive airway pressure (CPAP) interface components is a critical aspect of maintaining effective therapy and hygiene. The nasal mask, full-face mask, or nasal pillows that form the interface between the CPAP machine and the user’s respiratory system degrade over time with use, cleaning, and exposure to skin oils. As an example, consistent usage may lead to a breakdown of the silicone cushion, affecting the seal’s integrity.
Adhering to a regular replacement schedule offers several advantages. A properly functioning seal ensures optimal pressure delivery, maximizing therapeutic benefits and minimizing air leaks. Furthermore, regular exchange of components helps prevent the build-up of bacteria and allergens, contributing to better respiratory health and overall comfort. Historically, manufacturers have provided guidelines based on material degradation and hygiene concerns.
