NettetTotal lung volume, initial and final CO concentration, and breath-holding time are used to calculate DLCO. The recommended timing method used is the Jones and Meade method, which measures breath holding time at thirty percent of inspiratory time up to half of the sampling time. How do you calculate diffusion capacity of the lungs? Nettet5. apr. 2024 · Restrictive lung diseases such as pulmonary fibrosis most often decrease diffusing capacity (DLCO) because of scarring and thickening of the area between the …
