I don't know if I'm posting in the right place but I need your help! I'm studying COPD (BSN Student) at the moment and I'm just so confused, please don't tell me to google or read a text books or read journals because I have, I promise! So if someone has an exacerbation of COPD due to infection, what would be the peak flow readings be if it was mild? Also would a chest x-ray determine the cause of this infection or is it done simply to rule out cancer etc? And would a urine sample show any abnormalities due to copd exacerbation caused by bronchopulmonary infection?? I would really appreciate your help because COPD is very common and I know I will encounter it on clinical rotation!
