what is the pattern for mac value progression? Give order acronym and range progression.
HIESD (ie highest)–halothane, isoflurane (purple), Enflurane, Sevo (yw), Desflurane (blue), N20.
Values: 0.75 -(0.4)-> 1.15 -(0.45)->, 1.6 -(0.5)-> 2.1 Then 6.0 and 105
What is the blood:gas coefficient for Iso?
1.46
What is the blood:gas coefficient for Sevo?
0.65
What is the blood:gas coefficient for N20?
0.46
What is the blood:gas coefficient for Des?
0.42
What is the number pattern mnemonic and order of progression for the four blood: gas coefficients?
Iso–> Sevo–>N20–>Des (same order progression as mac values but N2O and Des flipped
Pattern: 4,5,6….1st (4–>6) [1.46], 2nd (6–>5) [0.65], and third (4–>6 again) [0.46]. For Des, bring “4” in tenths place down of .46 and subtract 4 from the hundreths place of 0.46. [0.42]
