My mom died from emphysema a couple of years ago. The idea is that the lung will expand but does not contract so, while you can breath in, breathing out is a difficulty. Try it yourself: you should breath out for twice as long as you breath in, expanding your lungs then squeezing them.
It is caused by many things: for seniors who were exposed to woodstoves with bad exhaust; for younger people, improper breathing; long term exposure to various gases and family history.
Because your lungs do not process oxygen breathed in naturally, the straight oxygen helps when inhaled directly from the tube attached to the supply.
Macular degeneration is a comomon side effect as eyes require oxygen to function.
Lungs do not repair themselves. Once the damage is done, it is done. By quitting smoking, you simply extend the time it takes to take effect.
High humidity can cause more trouble, along with hgih stress. With my experience, if there is a smoker in the house, they will not provide oxygen because it is highly flammable (at least the company we dealt with).
From my experience, three months is too long…should be monitored monthly to assure no side effects and to monitor progression. There is a place here called Westpark which run educational and “how to live with” breathing difficulties. It is not something which gets better with exercise or treatment. It continually gets worse, although time frames are different with everyone.
Eventually, even making the bed will become impossible without resting between.
I’m not trying to be the bearer of terrible news here but the more you are involved, the better. Get all the information you can and if you need to, call the doctor yourself. Explain the situation and ask appropriate questions: they may not give you the information at first, but they will know you exist and want to be involved and eventually that may change.
I’ll try to keep up with this post and post more but I can’t think about it too long otherwise I’ll fall apart.
