WebTwo cases of primary pulmonary hypertension are reported in which intrapulmonary shunting and severe hypoxemia developed during treatment with epoprostenol. In both patients, other causes of worsening hypoxemia, including pulmonary emboli or intracardiac shunting, were effectively excluded. Interestingly, the second patient had some evidence … WebIn order to study the relationship between infection and shunt malfunction, we followed a protocol over five years (54 V-P shunts) consisting of (1) removal of the malfunctioning shunt and replacement in the same surgical procedure with a new one or institution of an external ventricular drainage for 8 days (if there were clear signs of infection), (2) culturing …

One example is in miniature Christmas lights which are wired in series. When the filament burns out in one of the incandescent light bulbs, the full line voltage appears across the burnt out bulb. A shunt resistor, which has been connected in parallel across the filament before it burnt out, will then short out to bypass the burnt filament and allow the rest of the string to light. If too many lights burn out however, a shunt will also burn out, requiring the use of a multimeter to find the po… étui lg velvet 5g amazon
