My husband has been in to hospital 6 times so far this year, infections and he is a co2 retainer, he came home last week, with the above tablet, and so far he can breathe easy, so I do wonder why has it taken so long to find something else to give him, he is on inhalers, and oxygen at home, he is severe, but when I read the discharge notes it said he is End Stage Copd,no doctor at the hospital spoke to me about that, this time he had a blood clot in the lung, so now have to have injections, and have also started warfin. Is there anyone on here who is on that drug, and is it working for you? My husband has also got a leaking aneurysm in the stomach, 64 cm, cant do anything about it, also got aortic stenosis , again nothing they can do about that either, due to his copd, so everything is against him. How do you all cope? He has really gone down the last 8 months. sorry for rambling on, but when I read end stage copd, has got me thinking how long have we got, I will pleased to have some feed back. Thank you to you all and keep well.
