Monitoring
Instructions for Use Apollo SW 4.5n 165
Part Number: 9053586, 3rd edition
Anesthetic agents
The anesthetic agents are side-stream measured in
the same way as CO
2 and O2.
Mixture detection
Apollo automatically detects the anesthetic gas used
and switches the measurement and monitoring of
anesthetic gas concentration to the gas detected.
If there is a mixture of two volatile anesthetic agents,
the concentration of the secondary anesthetic agent
is displayed if the xMAC value is 0.1 MAC or greater.
The gas with the higher expiratory xMAC value is
displayed above the secondary anesthetic agent.
A secondary anesthetic agent becomes the main
anesthetic agent if its xMAC value exceeds the MAC
value of the main anesthetic agent by 0.2 MAC.
A mixture of more than two volatile anesthetic agents
cannot be reliably detected. In this case, the
anesthetic gas values are no longer displayed and an
alarm is generated.
Note: A mixture of more than two agents may lead
to a temporary time-out of the measured O
2
value.
WARNING!
Risk of patient injury
If the anesthetic agent displayed does not
match the label of the anesthetic vaporizer
being applied (open), make sure the vaporizer is
filled correctly.
