is typically the same as single agent
interference.
3) For CO2, N2O and Agents, maximum interference from each gas at concentrations within
specified accuracy ranges for each gas. The total interference of all gases is never larger than
5%

.
4) Only applicable for AION 03-type module, meaning the secondary agent interference on the
primary one.
5) For AION 02-type module, it is the interference provided that input of used anesthetic agent has
been done.
