JorVet soda lime is a highgrade granular product that effectively absorbs carbon dioxide that is produced as an anesthesia byproductIt is a mixture of calcium hydroxide CaOH2 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 CaCO3 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 Minimal dust No KOHminimizing chance of anesthetic reactions that produce toxins Irregular particle sizecreates more surface area Saturation indicator builtin changes from white to violet Particle size 48 USP Mesh 25mm5mm
