DLCO Meaning and
Definition
-
The term "DLCO" stands for "diffusing capacity of the lung for carbon monoxide." It is a medical measurement that indicates the efficiency of the lungs in transferring gases, specifically carbon monoxide, from the inhaled air into the bloodstream. DLCO is an important diagnostic tool used in evaluating lung function and diagnosing various respiratory conditions.
DLCO is determined by measuring the amount of carbon monoxide that diffuses across the alveolar-capillary membrane per minute. This is done by having the patient take a deep breath containing a known concentration of carbon monoxide, and then exhaling the air for analysis. The difference in carbon monoxide concentration between the inhaled and exhaled breaths helps compute the DLCO value.
A low DLCO reading can indicate impaired lung function due to a range of disorders, such as emphysema, pulmonary fibrosis, asthma, or chronic obstructive pulmonary disease (COPD). Conversely, a high DLCO reading might suggest certain heart conditions or excessive blood flow through the lungs.
DLCO values are often interpreted alongside other lung function test results, such as spirometry, to provide a comprehensive understanding of an individual's respiratory health. Monitoring DLCO over time can help assess the progression or treatment response of lung diseases. However, it is essential to note that DLCO alone cannot provide a definitive diagnosis and should be considered in conjunction with a patient's medical history and other clinical assessments.
