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 peak pressure is the pressure measured by the ventilator in the major airways, and it strongly reflects airways resistance. For example, in acute severe asthma, there is a large gradient between the peak pressure (high) and the plateau pressure (normal). In pressure controlled ventilation, the pressure limit is (usually) the plateau pressure due to the dispersion of gas in inspiration.
Originally Answered: What is the difference between pressure and stress? Pressure is often used with fluids (gases or liquids), whereas stress is more often used with solids. One major difference is that pressure only acts perpendicular to a surface, whereas stress can also be parallel to a surface as well as perpendicular to it.
