EBME Forums Forums Maintenance Technical Assistance infusion pump's occlusion pressure adjustment

Geoff Hannis
I'm much appreciative and thankful

Im 100% sure it is lack of proper operation case.It will be useful to me know and help
Im a woman

I reached 450 mmHg in setting occlusion pressure for optima vs, Fresenius infusion pump.I will pay attebtion to the sort of the set and the 2 diameters and gravity.
Much much much thankful

Sounds to me like one (or more) of the pumps are pumping back (building back-pressure) to other pumps.

Is it always the same pump that alarms (the top one in the stack, for instance)? Is the bag height (are the bag heights) "correct"? Are check-valves being used? Are Luer locks being "accidentally" closed against pump flow? Again, probably the only way to get to the bottom of this one is to observe what the staff are actually doing.

thank u i will take into account

I will collect all this and observe.

the rates used should affect too

Without actually being there (... I wish), it's difficult to know what else to suggest. But from the biomed tech's point of view I would ensure that I was happy that the pumps themselves were working OK (occlusion levels correctly set, and then checked out and (or) calibrated). In theory (at least) it is up to the medical and nursing staff to use them correctly. The biomed's role there (if any) is simply to *advise - but you could confirm that their set-up is sensible (if they will let you near it, that is).

Do you have access to the pumps in question (or are they constantly in use)? And what pump test equipment do you have?

I notice you are talking about the Fresenius Optima VS. Which alarm codes are being presented (this pump has both upstream and downstream pressure sensors)? There should be some nice graphics shown on the display, too.

* Which type of hospital are you at, by the way (government, private)? I only ask as back in my own happy days roaming around the Kingdom I found it necessary to do a fair amount of "hand holding" (or "helping the staff") - sometimes to an extent that would frankly be seen as unethical here in the UK. Not only direct involvement with setting up infusions (and CVP lines, and what-have-you) but also connecting up ventilators to patients, running the odd lab test, and even taking the occasional radiograph! I'm sure I'm not the only biomed of that era who was obliged to assist in such ways. Those were the days (?), but hopefully things have improved a bit (nursing staff wise) since then.

Im happy to have you here Geoff Hannis honestly

It sounds operator's Subject since the begin

I have access to the pump which is Fresenius Optima VS. Actually i'm trying to repair one of them at the moment

I was born in Jeddah .Definitely u depended on your self and had good times.
My hospital is "Al Aziziyah maternity and children hospital' in Jeddah and it is government

I received this error accidentally after dismantling and assembling without even changing the keyboard which i should change complying to the the action mentioned in the manual depending on the error for which i opened the device for.

I disconnected only the cables which are necessary to reach the keyboard.

It should be something so sensitive because it occurred with me again with a working device immediately after reconnecting the battery and power supply connector
