<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing shortness of breath lately and coughing up phlegm. I am afraid it could be emphysema.  <response>: I see. To confirm that, I will first recommend a radiographic imaging procedure. This includes a plain x-ray or X-ray computed tomography Scan ct to evaluate your lungs. We will also need to run some blood tests such as a complete blood count and hematologic tests to check for any infection. Lastly, we may need to check your kidneys with a kidney function test and may consider intravenous fluid replacement if necessary.
