Wide bore tubing, 20-40cm long.
Bottle – cleaned milk or juice bottle, water for irrigation bottle (from the hospital) or commercial bottle PEP device.
Water – avoid using tank water, if water for irrigation or distilled water is available use this, otherwise cooled boiled water from the kettle.
Detergent and food colouring (optional).
The CF physio will determine the length of tubing and the amount of water, as both of these components will change the pressure/resistance the child is breathing against.
