My husband is 62, works in a lumber mill. Never smoked. 7 years ago he was diagnosed with PMR. 2 years ago COPD, Asthma. He was in hospital almost every month in 2021 for up to 6 days at time. 2022 started ok but in March he got COVID. Almost died to much carbon dioxide . He then spent 4 days in hospital in July, 5 days end August , sent home for 1 day with oxygen tank on 3. He had never been on oxygen. It was 24 hours a day. Gave him major depression. Next day I couldn’t get his pulse ox over 84 even on 3 on tank. He spent 8 more days in hospital after that. In October had another stay in hospital.
He tried Nucala did not help. Now he’s on Dupixent every 2 weeks. Even though he just started it’s made a major difference.
When he’s in hospital he has so many Drs coming in he doesn’t retain what they say. I feel in dark all the time. All I want to do is make him better.
Yesterday he returned from his lung Dr so happy. He gained 17% lung capacity. He’s at 37% now. I had no idea it was that bad. He said he had never been told but I don’t know.
Can someone explain to me lung capacity? I mean obviously 100% is ideal but what has it meant that he’s been walking around at 20%?
