Figure 1.

(A) Photolytic measurement readings obtained at the wrist. Left (dark grey) bar depicts control patients. Right (light grey) bar depicts patients with septic shock. The open square boxes denote the three patients who died. Y-axis is nitric oxide (NO) measured by device in parts per billion. Patients with septic shock had significantly higher levels of NO measured by device when compared to controls (p-value = 0.004). (B) Graphical representation of photolytic measurements obtained during shock (left) and after resolution of shock (right). Photolytic measurements obtained after resolution were statistically significantly lower than the measurements obtained during shock state.
