Figure 3From: A graphical simulation software for instruction in cardiovascular mechanics physiology Examples of results obtained by students after working through the training instructions with the IHL model and using the default parameter settings. (A) Non-linear relationship between stroke volume (SV), central venous pressure (CVP) and contractility rates at a constant heart rate (HR) of 70 min-1; (B) Relationship between SV, cardiac output (CO) and HR at a constant CVP of 10 mmHg in absence of sympathetic stimulation of the isolated heart; (C) Change in systolic (downwards pointing triangle) and diastolic (upwards pointing triangle) blood pressure (BP) with increasing heart rate for arterial vessels with normal compliance (1.5 ml/mmHg) and reduced compliance (0.5 ml/mmHg)..Back to article page
