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.
Based on work at Mayo Clinic, it now appears that the core pathogenic factor in SIH is decreased CSF volume rather than decreased CSF opening pressure. Patients can have normal CSF pressure and yet have this syndrome, Dr. Mokri says. Even orthostatic headache, the most common symptom of SIH, appears to vary.
