Figure 5 Examples of bolus flow time calculation. Both flow and pressure criteria need to be satisfied for bolus flow (purple) (5A). If only the impedance criteria are met, but flow is interrupted by an increase in pressure due to vascular (5B) or crural contraction (5C), no flow is measured (yellow).
