A) End expiration: At rest, intrapleural pressure must remain slightly negative (here it is shown as -5 mmHg) as i) the lung is elastic and has a tendency to collapse or shrink, and ii) the fluid lining the alveolar surfaces generates surface tension that works to collapse the lung.
P max is the asymptotically maximal pressure that can be developed by the respiratory muscles at any lung volume and P i is the maximum inspiratory pressure that can be developed at specific lung volumes. This measurement also requires pressure transducers in addition.ean transit time is the area under the flow-volume curve divided by the forced vital capacity. Maximal inspiratory pressure (MIP) MIP, also known as negative inspiratory force (NIF) , is the maximum pressure that can be generated against an occluded airway beginning at functional residual capacity (FRC).
