Figure 3 Relationship Between Qthermo and Q
Circles indicate a proximal (prox) sensor position, squares indicate a more distal (dist) sensor position (3 and 6 cm from the tip of the infusion [inf] catheter, respectively). Closed points indicate a high infusion rate of saline (15 to 25 ml/min), open points indicate a low infusion rate (8 to 15 ml/min). The line indicates the line of identity. In Dog 1, only part of the measurements could be performed because of a rather severe stenosis at the site of the instrumentation. Q = true blood flow; Qthermo = blood flow as calculated by thermodilution.
