Using CPAP When You Have a Cold, Flu or COVID
Many people keep using CPAP through a cold or flu, using extra humidity, saline and sometimes a full face mask for congestion. For COVID-19, the AASM advises using CPAP in a separate room, washing hands and cleaning equipment as directed, and replacing filters and disposable parts after you recover.
Colds and congestion
A blocked nose makes nasal masks and pillows hard to use. Raise humidity for comfort, use saline spray, and consider a full face mask while you are congested if you have one.
If you cannot tolerate CPAP for a few nights, sleep on your side and avoid alcohol and sedatives. Restart as soon as you can.
COVID-19 guidance from the AASM
The AASM's patient FAQ (originally March 17, 2020, updated November 24, 2020) advises people with COVID-19 to isolate in a separate bedroom, and a separate bathroom if possible, where they can continue to use CPAP while sleeping alone.
It advises washing hands with soap and water before and after handling the device, mask, tubing and filters, cleaning CPAP equipment according to the manufacturer's instructions, and replacing filters and disposable accessories after you are free from the virus.
Cleaning while sick
Clean the mask daily with mild soap and water or mask wipes, and wash the tubing and water tub. Do not use ozone or UV cleaners; follow your manual.
After you recover, replace filters and consider new cushions and tubing, especially if your supplier's schedule allows it.
When to get medical help
Seek care right away for emergency warning signs like trouble breathing, as the AASM advises. Call 911 for chest pain or severe shortness of breath.
If you are using oxygen, have a lung condition, or use bilevel or ASV, ask your clinician in advance what to do during a respiratory illness.
Supplies that can help
Salt water spray that moistens and clears the nose, a simple aid for the congestion and dryness some people get on CPAP.
A water-based or saline gel applied inside or around the nostrils to soothe dryness and soreness from CPAP airflow.
Pre-moistened wipes for a quick daily wipe of the mask cushion, mostly to remove skin oils between proper washes.
The air inlet filter keeps dust and lint out of the machine and your airway; it is a cheap part that needs regular replacement.
Plain, mild dish soap is the cleaning agent most CPAP makers and the FDA point to for masks, tubing and humidifier chambers.
