4 Configuration Settings Appendix
• Ambient Pressure corrected MAC
(not available in the U.S.A or in clinical environments under FDA control.)
• Enhanced MAC Correction
(not available in the U.S.A. or in clinical environments under FDA control)
If Correction is set to Off, the uncorrected MAC is calculated, i.e the MAC value is not corrected for
ambient pressure, age, temperature or any other individual factors influencing the effect of volatile
If Correction is set to Amb. Pressure, the MAC is corrected for the ambient pressure measured
during the last zero calibration.
If Correction is set to Enhanced, the MAC value is corrected for the patient's age and temperature,
and the ambient pressure measured during the last zero calibration.
The age is derived from the Date Of Birth entry in the Patient Demographics window.
The temperature is taken from the currently measured value for one of the following temperature labels:
Tcore, or Tblood.
MACawk Determines whether the MAC awake numeric is displayed or not. The MACawk numeric can
only be calculated if Correction is configured to Enhanced.
