Hye friend, I have one unit of Drager Primus. Initiatly when run the self test, the valves/ventilator test failed. I check the ventilator and change the whole ventilator systems with the effective one. Then I run the self test, it shows leak (man.spot) failed and the reading is too high, 800 plus. And also the breathing system also failed.

I checked all the breathing circuit, still cannot find the problem... can anybody help me or anybody experienced the same problem.. thanks ya...

Do you still need help?

let me check I have a Friend that knows about drager machines

Hi:

my friend toll me that the leak must not be in the Breathing circuit
it could be in the Ataching system betwen the patient module and the machine (check the seals betwen the systems)

and may be the other problem is a leak with the APL valve


I hoppe this help

Have a great day

Thanks Diego.. So how to check the leaking at APL valve?
