Chest training
Keeping your lungs healthy
After a big operation, it can be harder to breathe deeply.
This can sometimes lead to chest infections.
Doing simple breathing exercises can help:
- Keep your lungs clear
- Remove mucus (phlegm)
- Help you recover faster
These exercises only take a few minutes each day.
Active Cycle of Breathing Technique (ACBT)
ACBT is a breathing exercise that helps clear mucus from your chest.
You can do it:
- Before your operation
- After your operation
- Sitting up, lying down, or in any comfortable position
ACBT has 3 parts:
- Relaxed breathing
- Deep breathing
- Huff
1. Relaxed breathing
This is gentle, normal breathing.
- Breathe in slowly through your nose
- Breathe out slowly through your mouth
- Keep your shoulders relaxed
- Keep your tummy relaxed
- Continue until your breathing feels calm
2. Deep breathing
This helps your lungs fill with air.
- Breathe in deeply through your nose
- Fill your lungs as much as you can
- Keep your neck and shoulders relaxed
- Hold your breath for up to 3 seconds
- Breathe out gently through your mouth
- Repeat 3 times
- Go back to relaxed breathing
3. Huff
A huff helps move mucus out of your lungs.
- Take a breath in
- Breathe out quickly and strongly
- Imagine steaming up a mirror
- Repeat 2 to 3 times
- Go back to relaxed breathing
You may need to cough after a huff to clear mucus.

How often should I do these exercises?
- Repeat the full cycle until your chest feels clear
- Try to do the exercises every day
- Do them more often if you feel mucus in your chest
After surgery
If you have a wound:
- Hold a cushion or folded towel over it
- Gently press while you huff or cough
- This helps reduce pain and supports your wound
