I'm new to caring for tracheostomy patients and just started caring for a 4 year old with a trach in her home. We were trained that the patients should never sleep with an HME (heat moisture exchanger), but per mom she sleeps that way every night... What have you all seen with regards to that, whether in a home or hospital setting? The mom looked at me like I was crazy when I told her it wasn't safe for the patient to sleep with it.
