Reservoir BagReservoir bags are bladder-type bags, made of latex-free material or silicone, ranging in size from 1???L to 8???L. The 3-L reservoir bag is the most frequently used in dentistry (Fig. 14.21). Although commonly used, latex-free bags deteriorate more rapidly than silicone bags, especially in areas in which high levels of atmospheric pollutants are found (the planet Earth).
The reservoir bag attaches to the base of the bag-tee, usually immediately below the emergency air inlet valve (see Figs. 14.19 and 14.21). A portion of the gas(es) delivered through the unit to the patient is diverted into the reservoir bag, where it may be used for any of several purposes.
