(a) If a shortage of the fresh gas delivery occurs (fresh gas flow < 150% of minute volume)
rebreathing will increase with a significant inspiratory CO2 and reduced FiO2 concentration.
(b) FiO2 will decrease due to entrainment of ambient air. No manual support of patient breathing
via Man / Spon possible. No volatile agents must be used.
(c) FiO2 will drop immediately. FiO2 may fluctuate. No manual support of patient breathing via Man
/ Spon possible. No volatile agents must be used. Take care that the connector for the absorber
is not blocked (by e.g. a plastic bag).
Setup when CO2-absorber incl. Clic-adapter is removed:
7 Only soda lime of lower quality (granular soda lime) is available
Use a dust filter on the reusable absorber
Part number: MX50115 (or as an alternative bacterial filter IBF MK02588)
Exchange the filter with every change of the soda lime
8 No fresh water trap for the gas measurement (Waterlock2) is available
Empty the water trap regularly, at the latest when it is half full
In this case, continue using the water trap as long as possible
Even if the water trap is blocked (swelling elements are soaked), leave it in place to protect the
gas measuring bench. Due to the blocked water trap, there is no gas measurement available.
Therefore, the fresh gas flow must be set to at least 150% of the MV. Volatile agents must not
be used. Check alternative monitoring solutions (e.g. frequent blood gas analyses, narrow
alarm limits for hemodynamic monitoring).
