Visual and Automated CT Measurements of Lung Volume Loss in Idiopathic Pulmonary Fibrosis.
AJR. American journal of roentgenology, 2019OBJECTIVE. The purpose of this study is to establish the relationship between CT markers of lung volume and pulmonary function test (PFT) parameters of lung volume in idiopathic pulmonary fibrosis (IPF). MATERIALS AND METHODS.

In vivo measurement of lung volumes in mice
Physiological Genomics, 2001We describe longitudinal measurements of functional residual capacity (FRC) in breathing mice using a clinical computed tomography (CT) scanner. Lungs of anesthetized mice from the A/J and C3H/HeJ strains were scanned over a 10-s period. Using a fixed threshold for CT density, we could accurately and reproducibly obtain the amount of air in the lungs ...

Chest, 2012
Measurement of lung volumes is an integral part of complete pulmonary function testing. Some lung volumes can be measured during spirometry; however, measurement of the residual volume (RV), functional residual capacity (FRC), and total lung capacity (TLC) requires special techniques. FRC is typically measured by one of three methods.

Clinics in Chest Medicine, 1989
Measurements of lung volume play an integral role in the laboratory evaluation of patients with known or suspected lung disease. Several techniques are available to measure absolute lung volumes (containing residual volume). It should be noted that these techniques measure different theoretical volumes and may produce different results in patients with

Measurement of lung volume with 81Krm in a dynamic scintigram
Nuclear Medicine Communications, 1987The meaning of 81Krm counts obtained in a dynamic series of gated lung ventilation scans was evaluated in terms of flow rate, lung volume, or the flow/volume ratio. Flow and volume signals were recorded together with scintigraphic events in 29 subjects breathing 81Krm and after its decay, 127Xe as a tracer of lung volume.

Electronic Integrator for Measurement of Partitions of the Lung Volume
Journal of Speech and Hearing Research, 1968An electronic integrator, for use with an airflow meter, was designed to overcome the disadvantages of respirometers when used for research in speech breathing physiology, such as the inherent inertia which may produce an undesirable impedance to the expiratory airstream.

Validation of a Novel Compact System for the Measurement of Lung Volumes
Chest, 2021Current techniques for measuring absolute lung volumes rely on bulky and expensive equipment and are complicated to use for the operator and the patient. A novel method for measurement of absolute lung volumes, the MiniBox method, is presented.Across a population of patients and healthy participants, do values for total lung capacity (TLC) determined ...

Acute lung injury monitored with radiolabelled transferrin and lung volume measurements
Acta Anaesthesiologica Scandinavica, 1989Anesthetized pigs (n= 12) were given oleic acid (OA) to induce acute lung injury. Three additional pigs were used as uninjured controls. Six of the animals were pretreated with terbutaline before OA infusion. 113mIn‐labeled transferrin and 99mTc‐labeled erythrocytes were used for tracing of extravascular plasma leakage.

Relationship between Exhaled Breath Condensate Volume and Measurements of Lung Volumes
Respiration, 2006<i>Background:</i> Exhaled breath condensate (EBC) is proving to be a technique which can sample markers of lung inflammation; however, many factors affect the collection process. <i>Objectives:</i> We hypothesised that lung volumes – tidal volume, minute volume and total lung capacity (TLC) – would dictate the volume of the EBC

Measurement of Forced Expiratory Flows and Lung Volumes
NeoReviews, 2004After completing this article, readers should be able to: 1. Describe the information that measurements of forced expiratory flow can provide in spontaneously breathing and mechanically ventilated infants. 2. Delineate how lung volume can be measured.
