Mean ± SD values for venous blood hydrogen ion concentration (pH), carbon dioxide partial pressure (pCO₂), oxygen partial pressure (pO₂), bicarbonate (HCO₃⁻), base excess (BE), and haemoglobin oxygen saturation (O₂ Sat) during spontaneous ventilation (SV) while inhaling 3.0% isoflurane in 100% oxygen in sulphur-crested cockatoos (Cacatua galerita galerita).
