Hi guys, my dad has had end stage copd for the past 6 years but only since August 2015 his health had deteriorate dramatically. He needs o2 during the day and wears a niv mask at night because he retains co2. He started on 0.5 litres of oxygen and about 4 months later it was put up to 1 litre to ensure his stats were 88-92 spo2. He was admitted to hospital on Saturday with high co2 and the usual infection and need of steroids. Yesterday the staff nurse said that the doctor was happy for him to return home and his O2 is being changed from 1 litre back down to 0.5 litres. His O2 levels was hitting 93+ on 1 litre but they'd rather it vary between 88-92. I'm a little optimistic that it's all good being in hospital a super clean environment but things are different at home and we live smack bang middle of steel works. Good or bad decision only time will tell.
