Hi there ...
Thank you for the question ...
No not all patients of COPD need home oxygen , it is the degree of severity of COPD that determines the severity of COPD .
In case of chronic chain smokers at some stage air ways expansion power reduces and they are unable to get oxygen for their body in that case oxygen is needed to fulfill the body requirements .
Ideally Pulmonary function test determines the reversibility of air ways function .
So some patients of irreversible pulmonary function test need home oxygen .
Regards ***** ***** luck .
