JorVet Soda Lime. Carbon dioxide absorbent granules. JorVet soda lime is a high-grade granular product that effectively absorbs
carbon dioxide that is produced as an anesthesia by-product. It is a mixture of calcium ydroxide Ca(OH)2 also known as lime plus a
smaller amount of sodium hydroxide NaOH. Upon exposure to carbon dioxide CO2, the calcium hydroxide converts to calcium carbonate
Ca(CO3). This prevents CO2 buildup in a rebreathing circuit. The sodium hydroxide acts as a catalyst in the process. No potassium
hydroxide (KOH) is present in JorVet soda lime; this helps to avoid the formation of toxic compounds such as Compound A and carbon
monoxide. JorVet soda lime has a pH color change indicator that changes from white to violet when the soda lime needs to be
changed. It will eventually return to its original color if not changed. Therefore, a good rule of thumb is to replace the soda
lime every time the vaporizer is filled.
