Cleaning and Caring for Tracheostomy Equipment

Cleaning suction catheters at home

Suction catheters must be cleaned after each session of suctioning. This helps prevent infection as well as helps cut down costs by reusing the same catheter for one week.

After suctioning the trach tube:

  1. Pour a few ounces of hydrogen peroxide into a small clean container.
  2. Suction hydrogen peroxide through the catheter until it is free of mucus. Wipe the outside of the catheter with a cloth or gauze wet with peroxide.
  3. Suction sterile salt water through the catheter until it is free of peroxide.
  4. Suction air until the catheter is free of water.
  5. Remove the catheter from the connecting tubing and let it air dry.
  6. Wrap it in a clean dry towel.
  7. Use it as needed with this cleaning process each time for up to 8 hours, then THROW IT AWAY.
  8. Follow manufacturer's instruction for cleaning and disinfecting your suction machine and humidifier. Do not allow water to stand in your humidifier when not in use.
