Predicting total lung capacity from spirometry: a machine learning approach [PDF]

Frontiers in Medicine, 2023
Background and objectiveSpirometry patterns can suggest that a patient has a restrictive ventilatory impairment; however, lung volume measurements such as total lung capacity (TLC) are required to confirm the diagnosis.

Size-matching in lung transplantation using the adjusted total lung capacity ratio [PDF]

JHLT Open
Background: Evidence guiding optimal size-matching in lung transplantation is limited, and no consensus exists. Most current approaches fail to account for the recipient’s underlying pathology.

The Effect of Lung Volume on the Size and Volume of Pulmonary Subsolid Nodules on CT: Intraindividual Comparison between Total Lung Capacity and Tidal Volume [PDF]

대한영상의학회지, 2021
Purpose To examine the effect of lung volume on the size and volume of pulmonary subsolid nodules (SSNs) measured on CT. Materials and Methods A total of 42 SSNs from 31 patients were included. CT examination was first performed at total lung capacity

Residual Volume and Total Lung Capacity at Diagnosis Predict Overall Survival in Non‐Small Cell Lung Cancer Patients [PDF]

Cancer Medicine
Background Residual volume (RV) / total lung capacity (TLC) ratio has been found to better predict functional impairments than spirometry and is associated with mortality in chronic obstructive pulmonary disease; however, it is rarely studied in lung ...

Comparison of diffusing capacity of carbon monoxide (DLCO) and total lung capacity (TLC) between Indigenous Australians and Australian Caucasian adults. [PDF]

PLoS ONE, 2021
Background and objectiveCurrently there is paucity of evidence in the literature in relation to normative values for diffusing capacity of carbon monoxide (DLCO) and total lung capacity (TLC) among Indigenous Australians. Hence, in this study we assessed

Preserved ratio impaired spirometry is associated with small airway dysfunction and reduced total lung capacity [PDF]

Respiratory Research, 2022
Background: Preserved ratio impaired spirometry (PRISm) refers to decreased forced expiratory volume in 1 s (FEV1) in the setting of preserved ratio. Little is known about the role of PRISm and its complex relation with small airway dysfunction (SAD) and

Can the single-breath alveolar volume be adjusted to estimate true total lung capacity? [PDF]

European Clinical Respiratory Journal
Background Total lung capacity (TLC) measured with single-breath gas diffusion (TLCsb) is systematically lower than TLC measured with whole-body plethysmography (TLCwbp) especially in patients with obstructive defects.

Baseline total lung capacity and all-cause mortality in restrictive pulmonary disorders: a meta-analysis [PDF]

BMC Pulmonary Medicine
Rationale Forced vital capacity (FVC) has been utilized as a surrogate for vital capacity (VC) in monitoring the progression of restrictive pulmonary disorders, particularly in clinical trials of idiopathic pulmonary fibrosis (IPF).

A More Comfortable Method for Hydrostatic Weighing: Head above Water at Total Lung Capacity [PDF]

Journal of Functional Morphology and Kinesiology
Hydrostatic weighing (HW) requires full submersion with the lungs at residual volume (RV) which is uncomfortable. Therefore, the purpose of this study was to find a more comfortable way to complete HW.
