TABLE 1.

The 10-Point Surgical Apgar Score

	0 Points	1 Point	2 Points	3 Points	4 Points
Estimated blood loss (mL)	>1000	601–1000	101–600	≤100
Lowest mean arterial pressure (mm Hg)	<40	40–54	55–69	≥70
Lowest heart rate (BPM)	>85*	76–85	66–75	56–65	≤55*

The Surgical Apgar Score is calculated at the end of any general or vascular surgery operation from the estimated blood loss, lowest mean arterial pressure, and lowest heart rate entered in the anesthesia record during the operation. The score is the sum of the points from each category.

*Occurrence of pathologic bradyarrhythmia, including sinus arrest, atrioventricular block or dissociation, junctional or ventricular escape rhythms, and asystole also receive 0 points for lowest heart rate.

BPM indicates beats per minute; mL, milliliters; mm Hg, millimeter of mercury.
