Safety

Conventional ‘standard’ absorbents have a good safety record. However, some safety considerations have been raised.

There is a very low, but real risk of the absorbent drying out. If this happens, there is then the potential for unwanted interactions between dry absorbent and volatile anaesthetic leading to generation of chemical breakdown products and heat.

Spherasorb and LoFloSorb have been developed specifically to address such concerns and offer additional safety benefits compared with standard soda lime formulation.

Prolonged flows of dry oxygen at a number of litres per minute can excessively dry absorbents.
