Fig. 13.

Contributions of open-loop and feedback gains. The apparent open-loop gain (A_ol: solid line), defined by Eq. 12, and apparent feedback gain (A_fb: dashed line), defined by Eq. 13, are plotted as functions of M under physiological control condition. For these simulations, the model uses the parameters from Table 1 with pressure given by P = (0.0001 mmHg·μl O₂⁻¹·min¹·g¹) M + 105.41 mmHg.
