Oxygen Supply to the Myocardium
This paper concerns aspects of oxygenation of the myocardium in relation to coronary artery flow and in relation to areas of ischaemic hypoxia. These results were obtained during the course of experiments designed to set up a myocardial ischaemia model and to investigate the effects of haemodilution on myocardial oxygenation. These studies involved the use of various inspired oxygen concentrations (FIO2’s) and cross-clamping of a terminal branch of the left anterior descending coronary artery, (Faithfull et al 1983a). The paper is inevitably somewhat ‘anecdotal’ in nature, but nevertheless does throw some light on the complicated nature of the oxygenation of myocardial tissue.
