I am hoping someone can help me work out the meaning of my fiance's lung function tests. He recently passed away at home I am thinking of respiratory or heart failure or both. We did realise his lung function tests were bad but did not realise he would pass away so soon. He was only 50 and although he was still smoking off and on I don't think either of us realised he was in such bad shape. I am really trying to understand his last lung test results to see if that will help me understand how bad his condition might have been.
I have fev 0.71 LITRES (20% PREDICTED) FVC 3.17 litres (70% PREDICTED)
severe gas exchange impairment dlcoC 23% PREDICTED and KCOc 32% PREDICTED
SPO2 was usually low 80's but had also been as low as 70's. The Hospital would not prescribe oxygen due to not quitting smoking. He was trying but obviously struggling with this. The Hospital really couldn't provide much more in the way of treatment until he stopped smoking so he was trying to focus on that.
Any Info would be appreciated.
