Pulmonary Tests and Procedures

Peak Flow Meter
Peak Flow Meter A peak flow meter for asthma is like a thermometer for a fever - it helps you monitor what's going on inside your lungs by measuring airflow out of the lungs. The meter can tell you if your airways are narrowing well before asthma symptoms begin. Learn how to use a peak flow meter, how to find your "personal best," and how to set your peak flow zones.

Pulmonary Function Tests
Pulmonary Function Tests (PFTs, Pulmonary Function Studies, Lung Function Studies/Tests, Airflow Assessment) Procedure overview What are pulmonary function tests? Pulmonary function tests (PFTs) are noninvasive diagnostic tests that provide measurable feedback about the function of the lungs. By assessing lung volumes, capacities, rates of flow, and gas exchange, PFTs provide information that, when evaluated by your doctor, can help diagnosis certain lung disorders. A normally-functioning pulmonary syst...
Oximetry
Oximetry (Oxygen Saturation, Oximetry, Ear Oximetry, Pulse Ox, Sp0 2 ) Procedure overview What is pulse oximetry? Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood. It is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose). How does pulse oximetry work? Oxygen in the air is breathed into the lungs. The oxygen then passes into the blood where the majority of the oxy...
Peak Flow Measurement
Peak Flow Measurement (Peak Flow Meter, PFM, Peak Expiratory Flow Measurement) Procedure overview What is peak flow measurement? Peak flow measurement is a procedure in which air flowing out of the lungs is measured. The measurement obtained is called the peak expiratory flow rate (PEFR), or peak expiratory flow (PEF). Peak flow measurement may be obtained using a spirometer, an instrument with a mouth piece that measures the amount of air breathed in and/or out and the rate at which the air is inhaled ...
Lobectomy
Lobectomy (Thoracotomy, Thoracoscopic Lobectomy, Removal of a Lobe of the Lungs, Lung Surgery) Procedure overview What is a lobectomy? A lobectomy is a surgical procedure performed to remove one of the lobes of the lungs. The procedure may be performed when an abnormality has been detected in a specific part of the lung. When only the affected lobe of the lung is removed, the remaining healthy tissue is spared to maintain adequate lung function. A lobectomy is most often performed during a surgical proc...
Lung Transplantation Procedure
Lung Transplantation Procedure (Transplant-Lung, Lung Transplant, Lung Graft) Procedure overview What is a lung transplant? A lung transplant is a surgical procedure performed to remove one or both diseased lungs from a patient and replace it with a healthy one from another person. The majority of lungs that are transplanted come from deceased organ donors. This type of transplant is called a cadaveric transplant. Healthy, nonsmoking adults who make a good match may be able to donate a part (a lobe) of ...
What Is Bronchodilator Reversibility Testing?
What Is Bronchodilator Reversibility Testing? Bronchodilator reversibility testing is used to help your doctor assess your lung function after you have been given a type of lung medication called a bronchodilator. It's often used in people who have asthma or chronic obstructive pulmonary disease, or COPD. This test uses spirometry and a bronchodilator. You are given the drug to relax your breathing muscles so that you can breathe more easily. The amount of improvement in your breathing after taking the ...
Computed Tomography (CT or CAT) Scan of the Chest
Computed Tomography (CT or CAT) Scan of the Chest (Chest CT Scan, Thoracic CT Scan, CT of the Thorax) Procedure overview Computed tomography (CT or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays. In standard X-rays...
Lung Scan
Lung Scan (Perfusion Lung Scan, Lung Perfusion Scintigraphy, Radionuclide Pulmonary Scan, Ventilation-Perfusion Scan, V/Q Scan) Procedure overview What is a lung scan? A lung scan is a specialized radiology procedure used to examine the lungs to identify certain conditions. A lung scan may also be used to follow the progress of treatment of certain conditions. A lung scan is a type of nuclear radiology procedure. This means that a tiny amount of a radioactive substance is used during the procedure to as...
Chest X-ray
Chest X-ray (Chest Radiography, CXR) Procedure overview What is a chest X-ray? A chest X-ray is a type of diagnostic radiology procedure used to examine the chest and the organs and structures located in the chest. Chest X-rays may be used to assess the lungs, as well as the heart (either directly or indirectly) by looking at the heart itself. Certain conditions of the heart may cause changes in the lungs and/or the vessels of the lungs. Changes in the normal structure of the heart, lungs, and/or lung v...
