Plethysmography is a standard method for studying pulmonary function in conscious,

spontaneously breathing laboratory subjects. The barometric plethysmography

technique measures flow and pressure changes that occur while the subject is breathing,

before and after exposure to a drug or other challenges. It is easily adapted to various

subject sizes and species, and is often used for longitudinal studies where the subjects

are studied for multiple hours on successive experiment days.
