Medical grade Soda Lime as per IP/BP/USP standards.
Soda Lime is a well balanced mixture of Calcium and Sodium Hydroxides, which have high Carbon Dioxide absorption capacity.
Use in Hospitals:
Soda Lime is used to absorb expired CO2 during Anesthesia (in Operation Theatres).
Soda Lime is a Carbon Dioxide absorbent of choice for major hospitals in India & across the world.
Soda Lime are in breathable gas applications where Carbon Dioxide levels need to be controlled, for example in medical anesthetic breathing circuits. In these applications, the breathable air is recirculated for re-use and therefore any exhaled carbon dioxide needs to be removed in order to prevent a build-up of carbon dioxide to toxic levels.
Soda Lime has application in Anesthetic systems in the medical operations to remove expelled Carbon dioxide due to respiration carried out by the patient or the user.
Soda Lime with Color Indicator:
Soda Lime becomes less effective during use, the granules change their color.
Color Indicator is available in 2 types:
Pink to White Indicator on absorption of CO2
White to violet Indicator on absorption of CO2
Medical Application:
Soda Lime is used in medical applications for removal of carbon dioxide from breathable gas in anesthesia circuits and in hyperbaric oxygen treatment chambers. Akron Healthcare manufactures Soda lime for many of the world's leading medical equipment manufacturers and leading hospitals as per their customized specifications to suit their needs.
Shape:
The granule shape of Soda Lime ensures maximum CO2 penetration into the particles, by minimizing the distance to the centre of the particle, thereby increasing the CO2 capacity of the product. It absorbs carbon dioxide in oxygen based therapy based metabolism, in closed circuit anesthesia, in estimation respirators, breathing apparatus etc. Exhaled gases are circled back to the canister where CO2 absorption takes place and water and heat are produced. The warmed and humidified gas joins the fresh gas flow to be delivered to the patient. In Soda Lime absorption, the Carbon Dioxide first reacts with water to form carbonic acid, which then reacts with sodium hydroxide to form a soluble carbonate. The soluble sodium carbonate then reacts with calcium hydroxide to form an insoluble carbonate and replenishes sodium hydroxide. Exhaustion of its activity is indicated by the dye and accordingly the color changes from pink to white or white to violet depending on the indicator used due to absorption of Carbon Dioxide (CO2).
Soda Lime granules are available in various shapes that include irregular pebble shaped granules, uniform shaped granules, cylindrical shaped granules, d-shaped granules and pellet shaped granules depending on the intended application and customer specification.
The water content can also be varied depending on the application.
The point to be ensured is that the shape of the granules should maximize CO2 absorption and minimize dust formation.
