MAC is a measure of potency; lower MAC indicates higher potency. A MAC value over 100% (like 105% for N2O) indicates that it is a very weak anesthetic, requiring a theoretical concentration higher than atmospheric limits to achieve anesthesia in 50% of patients.

Pharmacology
ACE inhibition has a beneficial impact on survival rates, functional status, and hemodynamics in patients with left ventricular systolic dysfunction.
In the renin-angiotensin system, a fall in perfusion pressure stimulates the juxtaglomerular cells in the kidney to release the enzyme renin.
Renin cleaves the decapeptide angiotensin I from angiotensinogen, a glycoprotein synthesized in the liver.
The octapeptide angiotensin II is formed by the action of ACE on angiotensin I.
Angiotensin II is a potent vasoconstrictor and stimulates the release of aldosterone and norepinephrine.
