Question

Which of the following sets of hemodynamic data is associated with early septic shock?

1) CI > 3 L/min/m2, PAOP > 10 mm Hg, SVR < 800 dynes/sec/cm-5, SvO₂ < 70%
2) CI > 3 L/min/m2, PAOP < 10 mm Hg, SVR < 800 dynes/sec/cm-5, SvO₂ > 70%
3) CI < 3 L/min/m2, PAOP > 10 mm Hg, SVR > 800 dynes/sec/cm-5, SvO₂ < 70%
4) CI < 3 L/min/m2, PAOP < 10 mm Hg, SVR > 800 dynes/sec/cm-5, SvO₂ > 70%

Answer 1

The set of hemodynamic data associated with early septic shock is CI < 3 L/min/m2, PAOP > 10 mm Hg, SVR > 800 dynes/sec/cm-5, SvO₂ < 70%.

Step-by-step explanation:

The correct set of hemodynamic data associated with early septic shock is 3) CI < 3 L/min/m2, PAOP > 10 mm Hg, SVR > 800 dynes/sec/cm-5, SvO₂ < 70%.

Septic shock occurs when a bacterial infection causes a significant drop in blood pressure, resulting in inadequate blood flow to organs and tissues. In this condition, cardiac index (CI) is low (<3 L/min/m2), pulmonary artery occlusion pressure (PAOP) is high (>10 mm Hg), systemic vascular resistance (SVR) is high (>800 dynes/sec/cm-5), and mixed venous oxygen saturation (SvO₂) is low (<70%). These hemodynamic changes indicate impaired organ perfusion and oxygen delivery, contributing to the severity of septic shock.
