Figure 1.

The modeled hemodynamic flow velocity responses due to visual stimulation are shown as relative changes to resting flow velocity. The resting flow velocity level was set to zero. During the acute phase of community-acquired pneumonia (CAP), the initial hemodynamic responses were delayed, resulting in a lag of blood flow adjustment of about 3 to 4 seconds as compared with the hemodynamic responses after recovery from CAP. After compensation of the initial mismatch, flow velocity levels did not differ at the end of the stabilization phase.
