I wonder if he has been to the hospital maybe they prescribed the nebuliser ? Or possibly the gp I know it’s hard to get oxygen at home
Your doctor will refer you to a specialist clinic if they think your symptoms can be helped by home oxygen therapy.
To check the amount of oxygen in your blood, you may have a blood test and an oxygen sensor may be attached to your finger or earlobe (a pulse oximetry test).
You may also be asked to breathe into a device that checks how well your lungs are working
