I've been seeing an 'expert' at Bangkok Hospital and, frankly don't trust him.
I did an FVC test, where I had to blow into a machine, then take some Ventolin inhaler and wait 15 minutes and then do it again.
I did this about 8 months ago, when first seeing the doc as I had difficulty breathing. After taking the Ventolin, there was a 12% increase in efficiency but on the recent visit, there was no increase. He said he suspects Emphysema now and had been going on about it definitely being Asthma before. I thought/think it might be Long Covid as I had no issues at all until getting the virus. I run 5 km 4 times a week, swim every day and play golf regularly and breathing isn't an issue now.
I find the test result strange and actually asked for the printed results but he 'forgot' to give them to me. The second test was exactly the same as the first, which I took a photo of when waiting.
If anyone has any experience of reading these things, or of Asthma, Emphysema, COPD, please tell me what you think. Was a bit if a shock him suggesting I have Emphysema as there is no cure!
Here's the photo and as I can see the lung volume seems OK. I have been taking Seretide acuhaler for 7/8 months, but not on the day of the test.
Also, I bought a thing to go on my finger to read the oxygen levels and it is usually 95-98.
