Can CPAP stop snoring?

Snoring happens when relaxed tissues in the upper airway vibrate as air passes through. In obstructive sleep apnoea, the airway can narrow repeatedly during sleep; CPAP sends air through a mask to support the airway and maintain airflow. Snoring may also be influenced by nasal congestion from allergic rhinitis or chronic sinusitis, sleep position, alcohol, or body weight. Treating one factor does not necessarily address every source of noise.

If CPAP has been prescribed, wear it for the whole sleep period and use the settings provided by the sleep service. Check that the mask seals comfortably without being overtightened. Clean the mask and tubing as directed, and mention dryness, blocked nose, pressure discomfort or air escaping around the mask. Side sleeping, avoiding alcohol near bedtime and addressing nasal symptoms may support comfort, but they do not replace evaluation for sleep apnoea.

Seek a sleep assessment if snoring comes with breathing pauses, gasping, restless sleep, waking headaches, poor concentration or daytime sleepiness. Contact the prescribing team if snoring continues after you use CPAP correctly, if the mask is difficult to tolerate, or if symptoms return after a period of improvement. Urgent care is appropriate for severe breathlessness, chest pain or sudden confusion.

Ask whether your symptoms need a sleep study, whether nasal treatment could improve mask comfort, how adherence is reviewed, and what to do if snoring continues.
