Do you need to zero the co2 on your monitor? we have to do ours once or twice a week

Have you cut down any dead space...shortening ET tubes etc ?

I guess you have checked all the obvious things - are you able to use a cylinder of oxygen for a bit and see if that gives you your answer? (am guessing you have some cylinders and hopefully they aren't just relying solely on the jennys!)

What is you FIO2%. Ideally this should be greater than 40% in the healthy animal. In the critically patient this should be closer to 80% and for resuscitation then the figure should be as close to 100% as possible.

with regards to the ETCO2 is this with a circle system or without or a mix. Circles, ensure that the soda line isn’t exhausted. non-rebreathing circuits ensure your flow rates are high enough for your patient.

it could potentially be concentrator. In my previous practice we have three supplying nine anaesthetic stations (Not all used at the same time) but they did used to struggle on days when we were busy.

might be worth contacting the supplier and getting them to come And review the set up

According to my capnograph yes I am getting rebreathing as there is a reading on the FiCO2 and my waveform is not returning to zero. When this occurred I tried increasing my oxygen FGF but it did nothing!

Also are you getting rebreathing or not? (Any inspired CO2?)

Hi, High ETC02 normally occur with hypoventilation but you have tried to sort that with reducing iso levels so another reason could be the animal is rebreathing C02 either by shallow resps or most commonly far too much apparatus dead space usually caused by overlong endotracheal tubes. Hope this helps,
