Introduction

Your Cough Assist is a machine that can help you clear secretions or ‘phlegm’ from your lungs. The aim of the treatment is to help you breathe in and out deeply and quickly. This can help when your own cough is not strong enough. The Cough Assist is usually given by a mask over your mouth and nose. The machine delivers a supported breath to make sure your breath in, is deep enough. After this, the machine helps you breathe out quickly and you would feel a gentle ‘sucking’ sensation.

The Cough Assist resource page has been developed in collaboration with Leeds Sleep and Complex Ventilation Service.

Why do you need a cough assist machine?

You have a Cough Assist machine to keep your chest healthy. The machine helps you to take deep breaths. It blows air into your lungs and then sucks the air back out. This is what happens when you cough. Coughing is the body’s way of clearing mucus from the lungs. If your cough is not strong enough to clear the mucus from your lungs, a cough assist machine can help.

Top Tips

  • Your machine may look a little different to the one in the video but it will work the same.  Refer to the manual that came with your machine if needed. 
  • It can feel strange when you first start to use your machine.
  • You can stop at any time.
  • When you use the machine, it blows air into all parts of the lungs. This can loosen any mucus that needs to come up. It might make you cough. This is good. You might not cough straight away. That’s OK- it’s still working.
  • If you can, agree a signal with the person who is helping you that means you want to stop
  • Do not use your cough assist machine when you are eating or drinking. It is best used on an empty stomach.
