I am trying this question a second time from a different perspective. I have been asked to change out the trach tubes for adult ventilator dependent pts. ( new cuffed tubes every month). I am a little uncomfortable doing this in the home with the minimal support available. The RT from the DME company is not authorized to change out the tube. How many of you have changed out trach tubes as part of your home health nursing practice? Any feedback will be greatly appreciated! Signed, A reluctant home health nurse
