My Dad COPD and CO2 retention
This is the first time I've done this, I'm hoping to find someone who understands what's happeneing to my father, He has COPD I think he is in the final stages, he has been on oxygen for about 18 months, and he keeps having episodes of CO2 retention, the last one was yesterday, he went into a kind of coma, and I thougt he was dying, but the hospital managed to bring him round eventually with this air machine and adrenalin, but he is now very muddled, seeing things that aren't there and angry, this is not the first time but it is the worst, I feel like he has had mild strokes, but no one seems to know. Is this normal? Does anyone know if this CO2 retention causes damage to the brain, as he seems to lose a little of himself with each time, when I left him at the hospital this afternoon he couldn't remember where he lived and he thought we had put him in a home. Does anyone know if this is part of COPD?
