Table 22. Suggested Shock Clinical Criteria*
SBP <90 mm Hg for >30 min:
a. Or mean BP <60 mm Hg for >30 min
b. Or requirement of vasopressors to maintain systolic BP ≥90 mm Hg or
mean BP ≥60 mm Hg
Hypoperfusion defined by:
c. Decreased mentation
d. Cold extremities, livedo reticularis
e. Urine output <30 mL/h
f. Lactate >2 mmol/L
* Systolic BP and hypoperfusion criteria need to be met for the shock diagnosis.
Table 23. Suggested Shock Hemodynamic Criteria*
1. SBP <90 mm Hg or mean BP <60 mm Hg
2. Cardiac index <2.2 L/min/m
2
3. Pulmonary capillary wedge pressure >15 mm Hg
4. Other hemodynamic considerations
a. Cardiac power output ([CO x MAP]/451) <0.6 W
b. Shock index (HR/systolic BP) >1.0
c. RV shock
i. Pulmonary artery pulse index [(PASP-PADP)/CVP] <1.0
ii. CVP >15 mm Hg
iii. CVP-PCW >0.6
* Diagnosis of shock requires ≥1 criteria to be present along with cardiac index <2.0 L/min/m
2
and SBP <90 mm Hg.
