hi, my partner has recently been diagnosed with copd, he went to the doctors and done the test they needed to do on a machine he had to blow into and when he went back the week later to get the results they told him he had 65% and 45% (i am assuming that is the lung capacity of each lung?) for months now his oxygen level (using a pulse oximeter) are 90 on a good day but can go as low as 84...i have been reading everything i can to find out what treatment he needs as the doctor just prescribed him an inhaler that does nothing for him, he has shortness of breath alot (even just going up or down the stairs and he is only 38), he gets dizzy, is restless during his sleep, and at times turn a blueish/grey colour...has anyone got any advise for me as the more i read the more confused i seem to get with it all...any answers will hopefully help me!
