VentiSorb is a carbon dioxide absorbent with excellent efficiency for use within closed circle systems.
VentiSorb is a medical grade soda lime prepared in granulated form. The individual granules are specifically non-uniform in shape and size so that CO2 filtration is maximised without restricting gas flow. VentiSorb offers excellent efficiency in absorbing carbon dioxide and other acidic contamination from the gas stream, with minimal interaction with anaesthetic agents. The active compound is naturally porous and hard which resists dust formation.
The use of VentiSorb in closed systems offers the following benefits:
- Increased Moisture Output
- Minimal Anaesthetic Agent Degradation
- Improved Heat Retention
Colour Change Indicator
VentiSorb is available in two different colour change indicators both conforming to International Standards.
Colour change indicators are either from Pink to White or from White to Violet. Both give clear visual indications of the level of active soda lime remaining available for CO2 absorption.
When exhausted, VentiSorb will change colour, indicating that the soda lime needs to be replaced. This should be used alongside CO2 monitoring to confirm compound exhaustion.
Pink to White
White to Violet
VentiSorb granules range from 2.5 - 5.0mm in size, allowing for a tightly packed layered canister increasing the efficiency of the CO2 absorption without significantly increasing resistance.
