i've had stage 4 copd for the last 9 years. none of the medications i've been given or treatments for this disease that i've been given in all that time would adversely affect anyone's breathing. worst case scenario would be that the treatment does nothing.
if you do not have copd but the er thinks you do and treat you accordingly can that adversly affect your breathing? . mom had an infarcted bowl took days for them to find it i told the er she had copd although she had no trouble breathing on her own except for one incident and was at that time diagnosed w/ copd. she never took oxygen or any breathing aids after the diagnosis but since she was diagnosed i told the er. when she died they put the 1st cause of death as breathing failure. septic shock infarcted bowl and heart failure i think were in there as 2nd and 3rd. .
