Tofranil (imipramine): 1  Is generally used in children older than 6 years. 2  Has a success rate of 10 to 50 percent. 3  Starts working in a few days. 4  Is relatively inexpensive. 5  Will likely stop working when the child stops taking the medication.
The plateau pressure is the pressure applied (in positive pressure ventilation) to the small airways and alveoli. It is believed that control of the plateau pressure is important, as excessive stretch of alveoli has been implicated as the cause of ventilator induced lung injury.
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).
