body plethysmograph a device used in pulmonary function tests to measure parameters such as functional residual capacity (FRC) and lung-thorax compliance (CLT). It consists of a large box in which the subject can be sealed so that volume of the thorax can be determined from pressure changes in the box.

Body plethysmographs can register gas compression volume during the flow-volume manoeuvre with no extra effort by the user, and the investigation of the possible changes in gas compression after administration of a bronchodilator may be valuable in assessing the effect of bronchodilators.
Inside the body plethysmograph with the door closed, the patient breathes normally on the mouthpiece.
The outdoor temperature was measured during the day of investigation at the place of the mobile body plethysmograph and included in the analysis as daily mean temperature.

A gas uptake/ whole body plethysmograph system (Figure 1) was used for unrestrained simultaneous measurement of all ventilation parameters.
The body plethysmograph lung function machine will be used in people with asthma, bronchitis and emphysema as well as those with heart and kidney disease.
In each experiment, a naive group of 4 male BALB/c mice (M&B A/S, Ry, Denmark), maintained under standard conditions, was exposed, head only, in separate body plethysmographs. We compared the mean effect for 12 mice for the period between the 11th and 20th minute to values obtained during the pre-exposure period, to determine the exposure effects.
