Review age, gender, smoking status, BMI, indication, flow-volume curves. Quality control. Three acceptable maneuvers with repeatable values: Two highest values of FVC and FEV1 should be within 150mL (100mL if FVC ≤ 1L) Good start (back extrapolation < 5% of FVC or 150 mL)

Pulmonary Function Tests (cont) DLCO (gas exchange) N=75– 120% Lung diffusion testing (ability of the body to absorb carbon monoxide from a single breath) is used to determine how well oxygen passes from the alveolar space (alveolar membrane permea bility) of the lungs into the blood. Low in ILD, pulmonary vascular diseas es, anemia, emphy sa ...

6 mar 2024 · Assessment of lung function involves measurement of how much carbon monoxide can be transported across the patient's lungs during a single breath (DLCO). DLCO may be useful for the diagnosis of pulmonary vascular abnormalities, or subtle interstitial abnormalities that don't affect the total volume of gas moving into and out of the lungs.
