Figure 4From: An integrated physiology model to study regional lung damage effects and the physiologic responsePhysioligal response to hypoxia exposure at rest. Ventilatory (a) and Alveolar PO2 (b) response to step change from room air to 9% O2 for 10Â minutes, followed by a return to room air. Alveolar CO2 is held constant via external supply (isocapnic hypoxia). Data from Reynolds [41]; experimental data presented as circles, model prediction is a solid line. Experimental alveolar O2 is approximated to be equal to end-tidal O2.Back to article page
