Fig. 3. Haemodynamic effects during the transition from apnoea (black bars) to gill ventilation (grey bars) in aerated water (PO2>130 mmHg) in S. marmoratus. Q, cardiac output; VS, stroke volume; fH, heart rate; PCV, central venous blood pressure; MCFP, mean circulatory filling pressure; PDA, dorsal aortic blood pressure. Values are mean ± s.e.m.; N=5–14. *Significant difference relative to no ventilation (1 cmH2O=0.098 kPa).
