Primary Outcome Measures

Name	Time	Method
<br> The following will be assessed once the final participant has finished the study (as these measurements require the total number of patients):<br> 1. Proportion of patients enrolled in whom we acquired interpretable regional oxygen saturation (rScO2) data (%) is assessed: 100 X total number recruited with interpretable data / total number recruited<br> 2. Proportion of patients enrolled in whom we acquired delirium data (%) is assessed: 100 X total number recruited with delirium data / total number recruited<br>
