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

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 ...

Lung volume measurements in infants with and without chronic lung disease
European Journal of Pediatrics, 1998Infants born prematurely who develop chronic lung disease (CLD) have airways obstruction and hence may have low lung volume. The aim of this study was to test that hypothesis and ascertain whether the nature of the comparison control group influenced the results.

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

Normal fetal lung volume measured with three-dimensional ultrasound
Ultrasound in Obstetrics and Gynecology, 2006To construct reference intervals for fetal lung volumes measured longitudinally using three-dimensional (3D) ultrasound, and to evaluate the effect of gender on lung size.This was a prospective, longitudinal study in the obstetric outpatient department of the VU University Medical Center, Amsterdam.

Extrathoracic airways changes during plethysmographic measurements of lung volume
Respiration Physiology, 1983In six healthy subjects cineradiographic studies during panting against a closed shutter showed widening and narrowing of the whole extrathoracic airways. At the epiglottic level, the mean lateral maximum diameter was 121% of the minimum diameter for an applied pressure of 11.4 cm H2O and 152% for 28.4 cm H2O, while posteroanterior diameter changes ...

Measurement of lung volumes from supine portable chest radiographs
Journal of Applied Physiology, 1979Lung volumes in supine nonambulatory patients are physiological parameters often difficult to measure with current techniques (plethysmograph, gas dilution). Existing radiographic methods for measuring lung volumes require standard upright chest radiographs. Accordingly, in 31 normal supine adults, we determined helium-dilution functional residual and

Measurement of high lung volumes by nitrogen washout method
Journal of Applied Physiology, 1994Studies on human infants suggested that thoracic gas volume (TGV) measured at end exhalation may not depict the true TGV and may differ from TGV measured from a series of higher lung volumes and corrected for the volume added. This was explained by gas trapping.

Influence of Lung Volume History on Closing Volume Measurement During Anaesthesia
Acta Anaesthesiologica Scandinavica, 1978Airway closure measurements were made with the bolus technique on eight healthy subjects, who were in a supine position prior to and during anaesthesia. Measurements were made on an expiration following vital capacity (VC) and 30% VC. Closing volume (CV) was calculated prior to anaesthesia, and closing capacity (CC)—functional residual capacity (FRC ...
