The EMMS head-out plethysmography system can be used in a variety of applications involving chronic studies. The animal is conscious and placed inside a head-out plethysmograph (eg. PLY 231). A latex rubber neck seal ensures that the thoracic chamber is airtight. Movement of the animal's chest as it breathes inside the plethysmograph is directly related to respiratory flow, and this is measured using a TPF 100 transducer across a pneumotachograph in the wall of the thoracic chamber. A number of parameters (such as tidal volume, breathing rate, inspiratory time and expiratory time) can be derived from the flow signal.
