Web9 de fev. de 2013 · DLCO is essentially a measure of the lung’s functional surface area and will be reduced when lung perfusion, volume or ventilation are reduced. If all you have are the DLCO results then VA can tell you something about a patient’s lung volume and gas mixing, but only in a negative sense. If VA is within normal limits for the patient’s TLC ...

WebThe equations for adjustment of predicted DLCO and KCO for alveolar volume are: DLCO/DL COtlc = 0.58 + 0.42 VA/VAtlc, KCO/KCOtlc = 0.42 + 0.58/(VA/VAtlc). DLCO and KCO were evaluated in 2313 patients. Subgroups of patients with asthma, emphysema, extrapulmonary lung disease, interstitial lung disease and lung resection were identified ...

Web12 de mai. de 2024 · Carbon monoxide transfer coefficient (often abbreviated as KCO) is a parameter often performed as part of pulmonary function tests. It is also often written as DLCO/VA (diffusing capacity per liter of lung volume) and is an index of the efficiency of alveolar transfer of carbon monoxide. Interpretation of KCO depends on other … WebThe equations for adjustment of predicted DLCO and KCO for alveolar volume are: DLCO/DL COtlc = 0.58 + 0.42 VA/VAtlc, KCO/KCOtlc = 0.42 + 0.58/(VA/VAtlc). DLCO … Web3 de set. de 2015 · Results. We show here that for the same value of DL CO (50 % predicted), K CO varied from 60 to 95 % predicted and V A from 55 to 85 % predicted in … incorporate workwear
