🏥1. Medical AnesthesiaIn anesthesia and intensive care, it absorbs exhaled CO₂ in the circulation loop of anesthesia machines and ventilators, allowing the exhaled gas to be re-inhaled after replenishment with oxygen and anesthetic gas, achieving "closed-loop anesthesia" and significantly conserving anesthetic gas and oxygen.
