SpiraLith®CaTM
SpiraLith®Ca CO2 absorbents contain a new easy to interpret color indicator system. The indicator bars will start to turn violet as the absorbent becomes consumed. Depending on conditions, the last bar may not change before exhaustion. Color change is useful in estimating the remaining absorbent life, but does not replace monitoring of FiCO2. The absorbent should be replaced when FiCO2 exceeds your hospitals limit (i.e. 0.5% volume or 4mm Hg).
