Continuous positive airway pressure (CPAP) therapy devices can generate various sounds during operation. These sounds can range from gentle humming and whooshing of air to more noticeable clicking, rattling, or whistling. A quiet operating volume is generally desirable for both the user and their bed partner. An understanding of the potential sound sources is crucial for troubleshooting and ensuring effective, comfortable therapy.
Quiet operation promotes better sleep quality and treatment adherence. Excessive or unusual sounds can indicate a problem with the device, such as a mask leak, improperly fitted tubing, or a malfunctioning motor. Addressing these issues promptly can improve the effectiveness of therapy and prevent potential complications. Since the introduction of CPAP therapy, manufacturers have continuously worked to reduce device noise levels for improved patient comfort.
