Hi everyone, I am a Biomedical Engineer working on a donated Dräger Apollo unit where we have no local factory support. The machine is booting up with a hard "System Fault! Device cannot be used. Notify DrägerService!" screen. The top status banners read "GAS + VENT FAIL" and "ID FUNCTIONS FAIL". This error persists even after swapping out the ventilator. I would love to get your opinions or any ideas on where to focus. Has anyone run into this specific combination of errors before? Any insights, troubleshooting ideas, or opinions from your past field experience with this would be incredibly helpful!

At the surgery center I work at we have an old AESPIRE S/5 Anesthesia Machine that gets regularly serviced and is in good condition. Recently, I will get a message while I am ventilating a patient that says “EXPIR reverse flow” and the inspiratory CO2 on the capnometer will go up quickly. I will then switch to manual (hand begging) and I’m able to bring the CO2 down. I will then go back on ventilator and it will act normal for a little while before this happens again. I have taken the whole ventilators module of the machine and cleaned and dried everything including the Bellows. The inspiratory valve is clean and I wipe it down. The expiratory valve is mostly clean but has had a little bit of CO2 absorbent dust on it. I have cleaned it off and wiped it down and it seems to function normally. But then when I’ve used that machine after that, it will eventually start doing the same thing. Do you have any suggestions? Is there another valve to be cleaned? I wouldn’t think so, but I can’t think of what else could be the problem. Please help.

I have found a 1/8 OD, 1/6 ID, urethane tubing rated at 105PSI, but I don't know the specs for the other tubing in the machine. I assume it is also urethane, at least 100PSI , but what is the ID and OD?

On the back of some Fabius Tiro Anesthesia machines, just above the power inlet socket,

there's a little coin shaped disk fastened to the cover plate externally. It appears to be stuck onto the metal 

back plate with no visible or obvious purpose/function. On the inside of the cover plate, there's nothing

associated with this disk. No wires, no protrusions, nothing. Does anyone know the purpose of this little unassuming disk?

I have an Anesthesiologist friend and curiosity is killing him. :-)

Anyone?
