Oana Klein MD MS, Northwestern University Feinberg School of Medicine, Division of Hospital Medicine, Department of Medicine, 211 E. Ontario Street, 7th floor, Chicago, IL 60611, USA. E‐mail: oklein@nmh.org. A doctor will take these factors into account and work out a predicted level of diffusion capacity. The normal range for DLCO is as follows: 80–120% of its predicted value for men 76–120% of its The measurement of oxygen diffusion capacity made so unpalatable by the need to sample arterial blood, usually this is something approximated from the diffusion of carbon monoxide. D LCO is the diffusing capacity for carbon monoxide, a measure of the efficiency of the lung as a gas exchange surface. Spirometry and diffusing capacity were collected in accordance with contemporaneous American Thoracic Society standards for the measurement of lung function.

The diffusion capacity of the lungs, as measured by the method of one inhalation of CO (DLco), is the ability of the lungs to diffuse oxygen (O2) to the blood and to drive off carbon dioxide (CO) from the blood to the atmosphere. Spirometry is a powerful tool that can be used to detect, follow, and manage patients with lung disorders. Technology advancements have made spirometry much more reliable and relatively simple to Spirometry Lung Volumes Diffusion Capacity Maximal Voluntary Ventilation (MVV) Maximal Inspiratory Pressure (Pi max) Maximal Expiratory Pressure (Pe max) Arterial Blood Gas (ABG) Walking Oxymetry Bronchochallenge Tests INDICATIONS: Pulmonary Evaluation: Presence of impairment Type of Pulmonary dysfunction Spirometry is an essential tool for screening, diagnosis and monitoring of restrictive and obstructive lung diseases like COPD or Asthma and as such is a valuable tool in all medical fields that are facing patients with dyspnoea.

The ERS-education website provides centralised access to all educational material produced by the European Respiratory Society. It is the world’s largest CME collection for lung diseases and treatment offering high quality e-learning and teaching resources for respiratory specialists. This distance learning portal contains up-to-date study material for the state-of-the-art in Pulmonology.

During the test, carbon monoxide is used because it has a high affinity for hemoglobin. This helps medical professionals determine how well oxygen can diffuse through the lungs into the bloodstream as well. Diffusing capacity is a measure of the ability of the lungs to transfer gas into the blood. Diffusion of gas to blood in the lungs is the most efficient when there is a high surface area for transfer, and when the blood is able to accept the gas being transferred Situations in which the diffusing capacity may be abnormally low include: Algorithm for interpreting results of spirometry. (DLCO = diffusing capacity of lung for carbon monoxide; VA = alveolar volume.) To determine the validity of spirometric results, at least three The diffusion capacity (D l), also called transfer factor, measures the capacity to transfer gas from alveolar spaces into the alveolar capillary blood. This process occurs by passive diffusion and is a function of the pressure difference that drives gas, the surface area over which exchange takes place, and the resistance to gas movement DIFFUSING CAPACITY.

• Spirometry: measures FEV1 (forced expiratory volume in 1 second), FVC (forced. The result of the test is called the transfer factor, or sometimes the diffusing capacity. A gas transfer test is sometimes known as a TLco test.
