| Popis: | Diffusing capacity of the lungs for carbon monoxide (DLCO) is an important pulmonary function test for the diagnosis and management of obstructive, restrictive and pulmonary vascular disease. The 2017 ERS/ATS standards for single-breath carbon monoxide uptake in the lungs recommends that a weekly DLCO simulation be performed with a calibrated 3-L syringe [1]. This type of simulation provides quality control values for both DLCO and alveolar volume (VA). After accounting for system dead space, an acceptable simulated VA is defined as 3±0.3L ATPD. We previously suggested that fixed arbitrary ranges for spirometry calibration verification were inferior to limits based on the performance of the device (±2 sd), which is commonly used to determine quality control ranges in laboratory medicine [2]. This recommendation was included in the 2019 ATS/ERS spirometry technical standard [2, 3]. We believe that a similar recommendation is appropriate for VA simulation.
