FiO2 (Fractional Inspired O2) monitoring

Display Features

NOTE
When FiO2 is followed by * (FiO2*), the * indicates the origin of this parameter is from a ventilator. For
more information on FiO2*, see the main IFU.

MultiGas Monitoring

If there is a secondary anesthetic agent already present while the Delta is admitted (taken out of
Discharge), that secondary agent is not trended. Powering on and admitting the monitor before starting
anesthetic gas measurements prevents this issue from occurring.
If the secondary anesthetic agent changes to the primary anesthetic agent, the agent is trended.

xMAC (MAC multiple)

The Delta monitor can calculate an xMAC value from all SCIO Four modules (SCIO Four, SCIO Four Oxi,
SCIO Four plus, and SCIO Four Oxi plus).
The xMAC value is a simple navigation aid for anesthetic agent delivery.
The xMAC is the MAC multiple calculated from the current expiratory measured values and the age-
dependent MAC values.
MAC (minimum alveolar concentration) is the anesthetic gas concentration in the blood at 760 mmHg
(1013 hPa) at which 50% of patients no longer respond to a skin incision with movement. The integrated
xMAC algorithm is based on the MAC values shown in the following table. The MAC values are dependent
upon the age of the patient. The values specified in the table (according to ISO 80601-2-55) apply to a
patient age of 40 years.
