A patient presented with apparent septicaemic shock. Full invasive cardiovascular monitoring revealed systemic hypotension, high normal cardiac output, and a low systemic vascular resistance. Maintenance of systemic vascular resistance and blood pressure was shown to be highly dependent on noradrenaline.
