I thought “Not again” two nights ago. My new 950 vent started giving me extra breath, not accelerated like the Trilogy had been doing, but enough to keep me awake, only when I was on my right side. Most likely because of the way the tubing hung at the bed’s side. Two skinny tube sensors, which helps the vent adjust to the air leak around my trach. My respiratory therapist said if these sensors are upside-down it would cause the machine to think I needed a breath. There are issues being solved. Tube positioning is key.
