[Respiratory work in panting in swine].
The dynamic work of breathing (Wdyn) has been measured during thermal tachypnea in pig anaesthetized and tracheotomized. During euthermia Wdin(cm H2O/R1/min-1) increases with ventilation (L.P.S.) according to Wdyn = 1,09 V2 + 1,33 V3; when body temperature rose above 39 degrees C for a given ventilation Wdyn decreases. In all animals has been observed a change of airways size and probably of respiratory tract of Weibel.
