Moisture Output - When the patient is incubated the upper airway is bypassed and results in a loss of humidity through exhaled gases. Oxygen and anaesthetic gases are dry and can have adverse effects and damage the mucosal wall of the respiratory tract.
While the nature of closed systems allows for expired gases to be returned to the patient and thus some of the moisture, VentiSorb plays an active role in producing moisture. The chemical reaction between the expelled carbon dioxide gases and that of the calcium and sodium hydroxide compound releases water molecules that can then be used to humidify the inspired air in lieu of the upper airway.
Heat Retention - VentiSorb's active ingredients whren exposed to Carbon Dioxide not only produces moisture but releases heat as a by-product. This reaction warms the gases and creates ambient humidity.
Minimal Agent Degredation - VentiSorb does not contain any added Potassium Hydroxide (KOH), therefore minimising agent degredation products such as compound A and Carbon Monoxide.
Colour Change Indicator - Ventisorb is available in two different colour change indicators both conforming to international standards. They are either from Pink to White or from White to Violet. Both give clear visual indicators as to the extent of the CO2 absorption and the life extent of the soda lime.
Particle Packing - Ventisorb granules range from 2.5mm-5.0mm in size, allowing for a tightly packed layered canister increasing the efficiency of the CO2 absorption without significantly increasing resistance.
