Looking after my NIV machine
Machine care
Keep the NIV machine clean and dust free.
If you are using a humidifier:
• you can wash the water chamber in warm soapy water or in the top drawer of
a dishwasher
• if you get a build-up of lime scale/mineral deposits, you can fill the chamber
with lemon juice and warm (pre-boiled) water and leave to soak for three to
four hours or fill with citric acid and warm water and leave for 30 minutes –
make sure that the solution is rinsed off thoroughly before re-using
One of the Chest Unit Team can show you how to clean the different parts of your machine and
give you any new or replacement parts you may need.
Mask care
Before putting on your mask, always wash your face to remove facial oils and make-up. Do not
put moisturiser on your face at night as this may stop the mask from sealing.
If you look after your mask it should last a year. If it breaks or starts to leak a lot, contact the
Chest Unit for a new one.
Daily
• Take the mask cushion or nose pillows off the straps. Clean with warm soapy
water, rinse and leave to dry.
• Do not use alcohol on the mask as this can damage it.
• Do not put it in the dishwasher or very hot water.
Weekly
• Take off the straps, wash in warm soapy water and leave to dry.
Tubing care
Clean the tubing before you first use it.
Weekly
• Detach the flexible tubing from the NIV machine.
• Gently wash the tubing with warm water and a mild detergent.
• Rinse well.
• Hang it over a chair or the back of a door to drip dry.
• Check the tubing regularly for holes. These can cause a high flow alarm to
sound.
