Chest X-ray with Placement Confirmation of Chest Tube (Radiographic Image Analysis)

This test is done to confirm that your feeding or drainage tube has been placed in the correct position inside your stomach or small intestine. Knowing the exact location of the tube allows your care team to deliver nutrition, fluids, or medication safely and helps prevent complications such as food or liquid entering your lungs.

A chest tube may be inserted to remove air, blood, or fluid from your chest cavity after surgery, trauma, or complications like pneumonia. This X-ray helps doctors verify the tube’s placement to prevent complications such as lung collapse or infection.

During the procedure, you will usually be seated or lying down while a nurse gently guides the tube through your nose or mouth. You may be asked to swallow or sip water as the tube moves into place. Once positioned, the tube is checked with an X-ray or another approved method to confirm it sits where it should, and it is then secured to your skin with tape.

You’ll lie on your back or side while the X-ray machine takes images of your chest. The radiologist will review the images to confirm the tube is positioned correctly—usually near your lung or pleural space—before you’re discharged.

Most people experience only mild, temporary discomfort, such as a gagging sensation, a sore throat, or minor nose irritation. Although uncommon, risks can include the tube passing into the airway, injury to the esophagus or stomach, bleeding, or infection at the securing site. Contact your care team right away if you develop trouble breathing, chest pain, vomiting blood, or severe abdominal pain.

The X-ray itself is safe and painless. Rarely, there may be mild discomfort from the tube insertion, but the X-ray itself doesn’t cause discomfort. If the tube isn’t placed correctly, it could lead to complications like lung damage or infection, so this step is critical.

The entire procedure usually takes between 15 and 30 minutes from start to finish. Inserting the tube itself often takes only a few minutes, while confirming its placement with imaging or other checks may add a short amount of extra time. Most people can return to their normal activities soon afterward unless their care team gives different instructions.

The X-ray itself takes just a few minutes. The overall process, including tube placement and verification, may take longer, depending on your medical condition and the hospital’s workflow.
