Over the weekend, my dad's (Severe COPD - Emphysema) sputum changed in color from whitish-pale yellow to yellow-green but clinically he seems still ok
O2 - is at 91 at rest , no noticeable SOB, Heart rate is at 80's , though voice is a bit hoarse (not sure if this was caused by the budesonide though)
I've already brought his sputum for Culture-Sensitivity test, but the result will still take 2-3 days.
Right now, I've already contacted his doctor, and still waiting for her reply / instruction.
