Design outcomes

Primary

Measure	Time frame
Changes in urine oxygen tension and the percentage of urine that can be collected from new devices	—

Secondary

Measure	Time frame
Agreement of measured urine oxygen tension with previous studies, comparison of measurement error between blood gas devices, correlation between arterial blood oxygen partial pressure and urine oxygen tension, correlation of arterial blood oxygen partial pressure and central venous blood oxygen partial pressure to urine carbon dioxide tension, relationship between trends in urine oxygen tension and acute kidney injury	—
