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.

EIT measurements and static prediction of lung volume
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992This paper discusses the possibility to compute static estimates of electrical conductivity of the lungs from EIT measurements by using the Boundary Element Method as an accurate three-dimensional solution technique to the forward problem. A relation is set up between these estimates and lung volume, without needing EIT images.

Fetal Lung Volume Measurements using 3D Ultrasonography
Ultraschall in der Medizin - European Journal of Ultrasound, 2011The aim of the study was to establish fetal lung, thoracic and heart volume nomograms using three-dimensional (3D) ultrasonographic measurements.For this purpose a total of 300 fetuses were examined between 18 and 34 weeks of gestation using Voluson 530 ME and Voluson 730 PRO (General Electic, USA) ultrasound devices with 5 MHz three-dimensional ...

Paediatric Respiratory Reviews, 2000
Although less commonly used in clinical practice than spirometry, lung volume measurements are helpful in assessing progress and response to therapy in situations where lung volume is likely to be increased, as in asthma or cystic fibrosis, or reduced secondary to pulmonary hypoplasia, pulmonary fibrosis, or musculoskeletal abnormalities.

Measurement of lung fluid volumes and albumin exclusion in sheep
Journal of Applied Physiology, 1989A radioactive tracer technique was used to determine interstitial diethylenetriaminepentaacetic acid (DTPA) and albumin distribution volume in sheep lungs. 125I- and/or 131I-labeled albumin were injected intravenously and allowed to equilibrate for 24 h. 99mTc-labeled DTPA and 51Cr-labeled erythrocytes were injected and allowed to equilibrate (2 h and
