Hi,

One of my Fabius' machines is giving erratic readings for Tidal Volume during Ventilation Mode with the following settings:
PMax = 40
Vt = 600
Frequency = 12
Ti:Te = 1:2:0
TiP:Ti = 10
PEEP = 1
(O2 flow is set to 10)

The machine has passed Leak/Compliance Tests, System Tests, Flow Calibration and O2 Sensor Calibration.

The screen shows a Vt of 580ml.
I have confirmed this with Datex S5 ACM and Fluke VT+.

When the Vap2000 (SEVO) is switched to 3%, the screen jumps to a Vt of 650ml +.

This conflicts with the S5 which stays at 580ml. The VT+ also measures 580ml.

The measured SEVO %age on the S5 also sits at around 3.5%.

I have exchanged the VAP2000 and the S5 but the difference remains. My other Fabius' also display similar readings as above.

I have emailed Dan at Drager, but wondered if anyone has any suggestions...
One of our US Navy Anaesthetists is fast losing confidence in the machine.

Thanks for your help...

Hi

What happens if you use air instead of oxygen?

Hi what do you mean by “Tiro M” is this a Military machine?
Please give us a call in the UK tech support centre 01442 211110 to discuss further.

Hi
Thanks for your responses... I'm trying to phone Draeger, but phone lines have been a problem recently.
Looks like the User just needs re-educating
Not long until the end of tour now, then it's time to look for a job... 1 year left and then it's time to start working for a living!!
Thanks again
