    Examples (not comprehensive)

    ASA Classification

    Normal healthy patient

    ASA 2

    Patient with severe systemic disease

    Substantive functional limitations, ≥1 moderate to severe diseases, e.g. poorly controlled diabetes or hypertension, COPD, morbid obesity, active hepatitis, alcohol dependence or abuse, implanted pacemaker, moderately reduced ejection fraction, ESRD on dialysis, premature infant <60 weeks post-conceptional age, history (>3 months) of MI, CVA/TIA, or CAD/stents

    ASA 3

    Patient with severe systemic disease that is a constant threat to life

    Recent (within 3 months) MI, CVA/TIA, or CAD/stents, ongoing cardiac ischemia or severe valve dysfunction, severely reduced ejection fraction, sepsis, DIC, ARD, or ESRD not undergoing regularly scheduled dialysis

    ASA 4

    Moribund patient not expected to survive without the operation

    Ruptured abdominal/thoracic aneurysm, massive trauma, intracranial bleed with mass effect, ischemic bowel with cardiac pathology, or multiple organ/system dysfunction

    ASA 5

    Declared brain-dead patient whose organs are being removed for donor purposes
