Design outcomes

Primary

MeasureTime frame
To compare RRI measurements of non-expert sonographers (intensivist and novice) to that of expert (sonographer) for interobserver variability and intra -observer variability.Timepoint: To compare RRI measurements of non-expert sonographers (intensivist and novice) to that of expert (sonographer) for interobserver variability and intra -observer variability.

Secondary

MeasureTime frame
To evaluate whether RRI on day 1 of admission can predict development of AKI in critically ill patients. To evaluate association of RRI with transient or persistent AKI.Timepoint:
