Heated humidifiers are for children who use a ventilator attached to a tracheostomy tube.

How does a heated humidifier work?

The air from the ventilator passes over heated water to become warmed and humidified before it enters your child’s lungs.

How to maintain a heated humidifier

As needed

  • When it is dirty, clean the humidifier with a clean damp cloth and either isopropyl alcohol or dishwashing liquid.
  • Replace the water chamber when it has a crack.

Daily

  • Empty the water chamber if using it only at night.

Every six months

  • Check the temperature probe for physical damage.

Every year

  • Check the temperature cables for damage. Replace if necessary.
  • Check the heater plate for deep scratching. Replace if necessary.
  • Check the heater wire adaptors for damage. Replace if necessary.

Precautions

  • Because of how it works, a heated humidifier can sometimes create an electric shock.
  • Take care to avoid “ra​in out” (build-up of warm water), as it can lead to bacterial growth in the tubing.
