Cleaning of the Circuit Tubing and Bottles:
This should be done after each patient has used the CPAP, and weekly if the same child is on
CPAP for over a week.
The CPAP circuit which comprises of an inspiratory and expiratory limb, bubble bottle, lid and
connections, humidification bottle and water trap must all be thoroughly cleaned as follows:
1. Remove any gross contamination by first washing all components thoroughly in a detergent
solution (soap and water). Use a clean container and brush the equipment thoroughly
under water to prevent splash and ensure all visible soiling is removed.
2. Rinse with water that has been boiled and allowed to cool to tepid. Let it dry.
3. Wash next in diluted bleach or disinfectant and leave soaking for one hour. Soak all items
together, do not keep use solution for subsequent components. Once used, bleach should
not be re-used or kept in storage, discard after use.
4. Rinse with water that has been boiled and cooled to tepid (rinse also inside, for example,
using a sterile syringe), let it drip dry over the sink, do not leave it coiled on the sink.
5. Check that there is no pooled water in the circuit. Store the circuit and bottle in a clean
plastic bag (labelled and dated). Store in the dry and clean area (separate from a soiled
equipment area).
