</div></div><div class="section-body" id="section-1"><p>A bronchoscope is a device used to see the inside of the airways and lungs. The scope can be flexible or rigid. A flexible scope is almost always used. It is a tube less than one half inch (1.27 centimeter) wide and about 2 feet (60 centimeters) long. In rare cases, a rigid bronchoscope is used.</p><ul><li>You will likely get <a test="test" href="./007409.htm">medicines through a vein</a> (IV, or intravenously) to help you relax. Or, you may be asleep under <a test="test" href="./007410.htm">general anesthesia</a>, especially if a rigid scope is used.</li><li>A numbing medicine (anesthetic) will be sprayed in your mouth and throat. If bronchoscopy is done through your nose, numbing jelly will be placed in the nostril the tube goes through.</li><li>The scope is gently inserted. It will likely make you cough at first. The coughing will stop as the numbing medicine begins to work.</li><li>Your health care provider may send saline solution through the tube. This washes the lungs and allows your provider to collect samples of lung cells, fluids, microbes and other materials inside the air sacs. This part of the procedure is called a lavage.</li><li>Sometimes, tiny brushes, needles, or forceps may be passed through the bronchoscope to take very small tissue samples (biopsies) from your lungs.</li><li>Your provider can also place a <a test="test" href="./002303.htm">stent</a> in your airway or view your lungs with <a test="test" href="./003336.htm">ultrasound</a> during the procedure. A stent is a small tube-like medical device. Ultrasound is a painless imaging method that allows your provider to see inside your body.</li><li>Sometimes ultrasound is used to see the lymph nodes and tissues around your airways, and small needles can be inserted there to obtain tissue and make certain diagnoses.</li><li>At the end of the procedure, the scope is removed. </li></ul><img title="Bronchoscopy" alt="Bronchoscopy" src="//medlineplus.gov/ency/images/ency/fullsize/23232.jpg" class="img-e" itemprop="image"/></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>How to Prepare for the Test</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">

Ask the provider who will do your bronchoscopy if and when to stop taking these medicines.</li><li>Arrange for a ride to and from the hospital.</li><li>Arrange for help with work, child care, or other tasks, as you will likely need to rest the next day. </li></ul><p>The test is most often done as an outpatient procedure, and you will go home the same day.

Until this medicine begins to work, you may feel fluid running down the back of your throat. This may cause you to cough or gag.</p><p>Once the medicine takes effect, you may feel pressure or mild tugging as the tube moves through your windpipe. Although you may feel like you are not able to breathe when the tube is in your throat, there is no risk of this happening. The medicines you receive to relax will help with these symptoms. You will likely forget most of the procedure. </p><p>When the anesthetic wears off, your throat may be scratchy for several days. After the test, your ability to cough (cough reflex) will return in 1 to 2 hours.
