EBME Forums Forums Maintenance Technical Assistance Anesthesia machine- Drager Primus

Yes, that's exactly the sort of problem faced in many places "overseas". As daft as it may sound, it can sometimes be more cost-effective (not to mention expedient) to fly someone out to hand-carry stuff back through. You need to be careful who you send, of course, as it has been known for such couriers never to be heard of again!

Ed,
Youve got the sun / heat I've got O2 cells / batteries that last longer. Mmmm whos got the best deal there then.

There is somethin gelse you can do.
Upgrade the machine to none consumptive gas bench.
I think this costs about £2k p/machine.

Karl your funny you are! You have also got Beer and bacon butties! I have nay But I do have a long catheter mount! 18" to be exact! How to get it to you?

Regards

Ed

This is intersesting! I will follow this up! Thanks

yesterday, I discussed with my collegues about this thing. Actually my hospital is quite new and not so much of patient. It is because my hospital is five star hospital, so it was so expensive. Normally CEO and oversea stuff enter here. But the amount of equipment is too many, 2000 and more.

Actually this machine was not so much used, but when I asking my friend, she tolds that eventhough the machine was not used, they still connect it to the Oxygen ports. Is this also can contribute in damaging the sensor?

Mammad
If the anaesthetic machine is connected and there is some sort of flow (basal or otherwise) going across the cell (sensor) and the concentration is >21% the cell will deteriorate quicker.
Best practise here is that at the end of each working list the machine is disconnected from gases and the gas lines hung over the top of the machine so that whoever uses it next is aware of the disconnection.
Also if the cell is on a flylead connector it can be disconnected in the same way.
Should the machine not be getting used for an extended period its best to remove the cell.

This maybe the cause of the shortening the lifetime of your O2 sensor. Pls note that your sensor is of the electrochemical type and the lifetime of the sensor depends on the amount of electrolyte and material present for the reaction as well as the exposure to oxygen. As Karl has pointed out earlier, disconnect the gasline when not in use.

Oxygen cells

Im sure I said that earlier Oh well!
