An EBUS is a procedure which allows the doctor to view the airways inside your lungs. A small flexible camera fitted with ultrasound is carefully passed through your mouth into your lung. The doctor will use an ultrasound scanner to look at the glands (lymph nodes) in the area and may take samples using a needle. Most patients have an injection called “conscious sedation” which aims to relax them and make them drowsy. Local anaesthetic is used topically to make the procedure more comfortable.
