Soda lime is widely used in various medical and industrial applications due to its ability to absorb carbon dioxide and moisture. In medical settings, it is a crucial component in anesthesia machines and closed-circuit breathing systems, where it helps to remove exhaled CO2 from the patient's breath, ensuring safe and efficient gas exchange during surgeries or respiratory treatments.

In diving and submarine operations, soda lime is used in rebreathers to scrub CO2 from exhaled air, allowing for the reuse of breathable gas in confined or underwater environments. It is also employed in laboratories and industrial processes where the removal of CO2 is necessary, such as in gas purification systems or controlled atmosphere storage.

Additionally, soda lime is used in the chemical industry for its alkaline properties, aiding in neutralization reactions and the production of various chemicals. Its versatility and effectiveness make it a valuable material in both life-saving and industrial applications.
