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, 2006
To 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, 1983
In 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, 1979
Lung 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, 1994
Studies 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, 1978
Airway 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 ...

Three‐dimensional sonographic volume measurement of the fetal lung

Journal of Obstetrics and Gynaecology Research, 2007
AbstractAim:  The objective of this longitudinal study was to evaluate the growth of the fetal lung in normal pregnancies, using 3‐D ultrasound.Methods:  3‐D sonographic examinations were performed on 14 appropriate‐for‐gestational‐age fetuses. Fetal lung volumes (left, right, and total lung volumes) were measured every 2–3 weeks from 20 weeks of ...

Accuracy of measured and predicted residual lung volume on body density measurement

Medicine & Science in Sports & Exercise, 1986
The effects of measured and predicted residual lung volume on the accuracy of body density and percent fat (%Fat) were investigated. Adult fitness subjects (N = 46) had residual lung volume measured with the oxygen dilution method while those from an athlete sample (N = 134) utilized the nitrogen washout technique.

Measuring end expiratory lung volume after cardiac surgery.

Acta anaesthesiologica Belgica, 2012
The aim of this study was to evaluate the interest of end expiratory volume (EELV) measurement after cardiac surgery.After stabilization, four EELV measurements were performed at one hour intervals during three hours using the nitrogen washout technique. EELV was compared to the predicted functional residual capacity (FRC) volume.

Dynamic chest radiography measurements correlate with conventionally measured lung volumes

Clinical respiratory physiology, exercise and functional imaging, 2019
Introduction: Dynamic chest radiography (DCR) is a novel technology that allows real time observation of respiratory kinetics and measurement of lung volumes during the respiratory cycle. Aim: To correlate measurements of lung area during deep inspiration on posteroanterior (PA) and lateral DCR images and derived lung volume with Total Lung Capacity ...
