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.
The pressure exerted by a column of liquid of height h and density Ï is given by the hydrostatic pressure equation p = Ïgh, where g is the gravitational acceleration. Fluid density and local gravity can vary from one reading to another depending on local factors, so the height of a fluid column does not define pressure precisely.
