Whole Body Plethysmography: Practical Considerations
Paediatric Respiratory Reviews, 2016Pediatric pulmonary plethysmography is an important tool used in the diagnosis of lung diseases. Understanding the physiology underlying the functioning of the test can aid the health care provider in its interpretation. The following article reviews the basic science behind whole body plethysmography, and provides an overview of the types of ...

Accuracy of Whole-Body Plethysmography Requires Biological Calibration
Chest, 2009Specific airway resistance (sRaw) measured by whole-body plethysmography in young children is increasingly used in research and clinical practice. The method is precise and feasible. However, there is no available method for calibration of the resistance measure, which raises concern of accuracy.

Barometric whole body plethysmography in mice
Journal of Applied Physiology, 2005There has been significant utilization of the technique described by Hamelmann et al. ( Am J Respir Crit Care Med 156: 766–775, 1997) in which a parameter, enhanced pause (Penh), related to airways responsiveness is noninvasively measured by unrestrained plethysmography (UP). Investigating this technique, we sought to answer these questions: 1) How do

Simplified Whole Body Plethysmography to Characterize Lung Function During Respiratory Melioidosis
Journal of Visualized Experiments, 2023Surrogate animal models of disease are subject to the 3Rs of Responsible Research. There is a frequent revisiting of refinements to animal models to ensure that both animal welfare and scientific insights advance with the availability of new technologies.

Precision of measurement and body size in whole-body air-displacement plethysmography
International Journal of Obesity, 2001To investigate methodological and biological precision for air-displacement plethysmography (ADP) across a wide range of body size.Repeated measurements of body volume (BV) and body weight (WT), and derived estimates of density (BD) and indices of fat mass (FM) and fat-free mass (FFM).Sixteen men, aged 22--48 y; 12 women, aged 24--42 y; 13 boys, aged 5-

Use of Whole-Body Plethysmography to Compare Bronchodilator Inhaler Efficacy
Respiration, 1998Whole-body plethysmography is not included in guidelines from regulatory authorities for the development of treatments or delivery devices for lung disease, despite its potential advantages compared to spirometry. Two separate studies were undertaken to assess the use of specific airway conductance (sG<sub>aw</sub>) as a pharmacodynamic ...

An improvement in whole body plethysmography.
The American review of respiratory disease, 1975A simple method for greatly reducing thermal drift and acoustic noise in constant-volume, whole body plethysmography is described. Evaluation and adjustment for any particular clinical application can be carried out in a few moments. The device itself consists of a 20- to 25-gauge needle, a "Y" tube, and a 1-liter or more vessel, and may be assembled ...

Airway reactivity measured by barometric whole-body plethysmography in healthy cats
American Journal of Veterinary Research, 1999Abstract Objective To assess the validity of barometric whole-body plethysmography (BWBP) as a means of monitoring airway responses to induced bronchoconstriction in healthy cats. Animals 8 healthy cats without history of bronchopulmonary disease or exposure to indoor tobacco smoke.
