The Expiratory Flow Pattern and the Neuromuscular Control of Breathing in Cats
During spontaneous breathing inspiratory muscle activity does not stop immediately at the start of expiration, but decays at a rate which can be influenced importantly by pulmonary receptors. 1 When the contribution of this decaying activity to the expiratory flow pattern is suppressed by a short end-inspiratory occlusion, the time constant of the respiratory system (τRS = RRS/ERS) can be estimated from the expiratory flow pattern using equation 1 and P(t) = 0.4
