what is maximal inspiratory pressure
Mean 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).It is a marker of respiratory muscle function and strength.ean transit time is the area under the flow-volume curve divided by the forced vital capacity.
