Hi All, I have a question in relation to COPD in which I've struggled to find the answer too. I think I know the answer to it but just wanted clarify. Today at work I had a patient with COPD. I'm aware with COPD to not put the 02 up higher than 2 L. When I checked the sats on 1 L they where around 78-81%. With the patient asymptomstic. I put it up to 2 L just to help that bit more. We are aiming 88% above. My in charge said that when the patient was sitting at 95% they where to much so to reduce the 02. Is that because the 02 on and being 95% it would've increased meaning to much CO2 in the blood going around ? I know this is probably a silly question and I know why we don't have to many litres on but not sure why she said 95% was to much for this patient. Did she mean whilst the oxygen was on ? Thanks heaps!!
