To diagnose a respiratory infection, the doctor will ask you about your symptoms and perform a physical exam of the affected area. During the exam, the doctor will focus their attention on your breathing to see if they are able to detect inflammation or fluid in the lungs. The doctor will use a stethoscope to listen to your lungs while you breathe in and out in order to detect any abnormal sounds. Part of the exam will also include a check into your nose and ears, as well as a check of your throat, both by feeling the glands in your neck and through the mouth. An x-ray or CT scan may be ordered in the case of a lower respiratory infection to provide a visual of the lung condition. Additionally, a lung function test can be performed using a pulse oximetry. This is used to measure the amount of oxygen that is getting into the lungs. The doctors at Physicians Now Urgent Care are very familiar with respiratory infections and are able to diagnose them quickly and easily. With the lab and x-ray services on-site, additional testing can be done while the patient is still in the clinic in order to confirm the diagnosis in one visit so the patient can leave with a complete treatment plan.
