Sit up as much as possible and place the mouthpiece of the incentive spirometer in your mouth. Make sure you make a good seal over the mouthpiece with your lips.

  • Breathe out (exhale) normally.
  • Breathe in (inhale) slowly - the white piece in the incentive spirometer will rise as you breathe in.
  • Try to get this piece to rise as high as you can.
  • Usually, there is a marker placed by your physiotherapist as a goal to aim towards. This will be changed regularly to help you improve.
  • A yellow ball will also rise. Aim to keep the ball in the middle of the chamber while you breathe in.
  • If you breathe in too fast, the ball will shoot to the top.
  • If you breathe in too slowly, the ball will stay at the bottom.

Your physio will advise you how regularly you need to use your spirometer
