1
New cards

Lactate increases during

anaerobic metabolism

2
New cards

Production of lactic acid

  • Glucose → Pyruvate → kreb’s cycle

  • If decreased O2 then:

    • Glucose → pyruvate → Lactate

3
New cards

Testing for Lactate

Lactate → Lactate oxidase → pyruvate + H2O2

H2O2 + reduced dye → peroxidase → oxidized dye

4
New cards

Normal Lactate value

0.5-1.5 mmol/L

5
New cards

Type A Lactic Acidosis

  • Decreased O2

  • MI, heart failure, shock, pulmonary edema

6
New cards

Type B Lactic Acidosis

  • Decreased proper metabolism → Increased lactate
