For example, the Des concentration at 1 MAC of a 60-year old patient is
.
The AG module measures 4% of Des, 0.5% of Hal and 50% of N
2
O in the patient’s end-tidal gas:
NOTE
•
The formula above is only suitable for patients who are older than one year. If the patient is less than
one year, the system uses one year old to do age correction.
19.9 Changing AG Settings

2
concentration in the gas mixture.
The
O2 Compensation
setting is available only when the AG module does not incorporate the O
2
module. If the
