Air leak: Air leaking from lung tissue into the chest cavity.


Air leak localization: Process by which an air leak in the lung is found.


Airway: The tubes in the lungs that pass air to and from the lung tissue.


Anesthesia: A medical procedure that makes the patient unconscious and makes the body insensitive to pain.


Asthma: Swelling of the airways in the lung, making breathing difficult.


Atelectasis: Collapse of all or part of the lung.


Balloon Catheter: A narrow, flexible tube with a small balloon at the end.

Bronchitis: An infection that causes inflammation of lung tissue.


Bronchoscope: A narrow, flexible tube, with a camera on the end that is used to see the lung airways.


CT Scan: An image taken of a body part.


Catheter: A narrow, flexible tube used to deliver medicine or medical devices inside the body.


Chest drainage system: A device that allows medical staff to measure and monitor an air leak.


Chest tube: A plastic tube that is inserted through the skin and rib cage and into the chest cavity to allow air and fluids leaking from the lung to exit the body.


Chest X-ray: a picture of the chest that shows your heart, lungs, airway, blood vessels, and lymph nodes.


Contraindication: Reason not to use the device/therapy.


Expiration: When a person breaths out.


Forceps: A common tool used in medical procedures to help doctors grab onto tissue and other objects in the body.


Intubation: Placement of a plastic tube into the mouth and down into the airway so that a person can be put on a breathing machine or so that a procedure can be done.


Lobectomy: Surgery to remove a lobe of the lung.


Lung Volume Reduction Surgery (LVRS): A major surgery in which more than one portion of the lung is removed.


MRI: Magnetic Resonance Imaging. A method for taking pictures of your internal organs.


Nitinol: A metal made of nickel and titanium. This is a common material used in medical devices.


Pleurodesis: A procedure that causes the outside of the lung to stick to the inside of the chest cavity to prevent the lung from collapsing.


Pneumonia: A lung infection with symptoms like a cough, fever, and difficulty breathing.


Polymer membrane: A thin sheet of flexible plastic. This is a common material used in medical devices.


Prolonged air leak: An air leak that lasts for 7 or more days.


Re-operation: The chest is surgically re-opened and a new attempt is made to close the leaking lung tissue.


Respiratory compromise: Breathing difficulty — causes less oxygen to be available to the body and negatively affects bodily functions.


Sedation: A medical procedure in which medicine is given to the patient to make him or her comfortable and unaware of pain during surgery. It relaxes the central nervous system and can cause sleepiness.


Segmentectomy: Surgery to remove a segment (small portion) of the lung.


Significant air leak: An air leak that is severe and/or produces other health problems at the same time.


Subcutaneous emphysema: Occurs when air gets into tissues under the skin.
