Table 1. Clinical shock severity stratification scoring system.

	0 pts	1 pt	2 pts	3 pts	4 pts	5 pts
Maximum Heart Rate (beats/min)	< 100	100–120	> 120
Minimum Systolic Pressure (mm Hg)	≥ 100	90–99	80–89	< 80
Maximum Lactate (mmol/L)	< 1	1–1.9	2–3.9	4–7.9	8–11.9	≥ 12
Total score (pts) = Heart Rate + Systolic Pressure + Lactate
Shock severity: Mild = 0–2 pts, Moderate = 3–5 pts; Severe = 6–10 pts
