Shunts usually consist of three parts: 1. Proximal end that is radiopaque and is placed into the ventricle of the brain. This end has multiple small perforations. 2. Valve - this allows for unidirectional flow. Some shunts can be adjusted to various opening pressures (called programmable shunts). Usually has a reservoir that A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region. In other words, the ventilation/perfusion ratio (the ratio of air reaching the alveoli to blood perfusing them) of those areas is zero. csu chico school of education tpe rubric word
