FIGURE 4

Test of the constancy of the transfer function at a high femoral flow rate (during infusion of adenosine triphosphate into the common iliac artery at a rate of 1.0 mg/min). The situation is similar to that of figure 3. Lower panels: two injections 4 sec apart. In this case the mean transit time remained constant at 3.1 sec and the transfer function was also the same despite the difference in form of the two curves, thereby suggesting that the arterial segment may be considered to behave as a linear system.
