"Hypoventilation" is terminology that is generally reserved to mean ventilation is inappropriately low for the carbon dioxide present. These patient's will have an increased PaCO2. Restrictive diseases decrease TLC (in fact are definded by a decreased TLC) but they do not necenssarily cause "hypoventilation". Tidal volumes and respiratory frequency can be normal. Better to say decreased compliance is associated with lower lung volumes.
Wow, thank you for such an awesome breakdown of lung disease and why how and when of it , I have restrictive lung disease but but what you have explained I think it is from a little bit of all of them. I don’t know how long you need to be exposed to aspestos but my landlord cut a hole in my wall to fit an air conditioner, it was dust from a to b he didn’t cover his lungs nor when he finished did I when I vacuumed it up, then it was in the house I guess being sucked up and spat out again over and over for the time I lived there, and this was 15 years ago. I also used to smoke, I then turned to vapours to get off smoking, it worked but not until the second round and it’s caused sticky fluid into my lungs I’m sure, when I lay down I have wearing and my lungs also have calcified Granuloma, the bottom has traces of old infection, the left middle has collapsed. I have very high arterial blood gases and did have left sided heart failure which seems to have gone away but I have no air on exghaustion, now it’s less and less activity I’m even labouring moving my body in a seated position, I do have a very swollen tummy and edge a feet and legs high blood pressure and cerebral small vessels disease so now I’m on medication three years which has put 36 kg on me which is cause obesety pressure aswel, so when I say I think I have all three you mentioned all my symptoms and yes really bad arthritis, so still I can’t tell which one caused it so don’t know without a Biopsie or further testing what way to treat it. Your not a doctor and I’m so greatful you have helped me understand how the lungs work and how these diseases effects the lungs and why they behave the way they do, the different symptoms etc. in the end you got fast and I had to rewind a couple of times to write it down but your very good at explaining with word and picture. I can now go to my doctors I have a colonoscopy coming up in 7 days and need to explain some things to my anesthesiologist as my New GP only just told me what my old GP was sitting on since February when I had the spirometer test and never said anything yet I suffer every day struggle to breath, it’s getting worse and I need some attention about it, it also explains to me why my body aches so bad after two hours or more of sleep, I’m not getting oxygen to my organs I get headaches and I thought my kidneys weren’t cleaning my blood properly I also have a liver 4 cm bigger than Normal with non alcoholic fatty liver disease which by what your saying the restrictive lung disease can also effect the liver or the liver the lungs, so again, not sure which way started off the bad lungs, need further evaluation thank you for helping me be assertive in asking for what I need to get done.
