Intraoperative Surgical Apgar (Gawande 2007 Table 1) from estimated blood loss,
Intraoperative Surgical Apgar (Gawande 2007 Table 1) from estimated blood loss, lowest mean arterial pressure, and lowest heart rate, summed to a 0–10 total. Returns score_le_4 because scores ≤4 were associated with 58.6% 30-day death or major complication in the validation cohort (9–10 associated with 3.6%). Deterministic published arithmetic with citation; not Virginia Apgar; not operative clearance.
