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.
a unit of pressure equal to 1333.22 dynes/cm2, or 1.33322 millibars. One torr is the pressure required to support a column of mercury 1 mm high when the mercury is of standard density and subjected to standard acceleration. These standard conditions are 0Â° C and 45Â° latitude, where the acceleration of gravity is 980.6 cm/sec2.
