Modeling Fluid Resuscitation by Formulating Infusion Rate and Urine Output in Severe Thermal Burn Adult Patients: A Retrospective Cohort Study

Table 1

Variables, definitions, and related equations for the proposed model.

Variable	Definition	Equation
Basic infusion rate	The empirical infusion rate that was estimated by time of postburn and total body surface area burned.	(3)
Overall ratio	Total urine output divided by all fluid infused by the end of time .	(4)
Instant ratio	Ratio of urine output rate and infusion rate at time .	(5)
Predicted urine output	The predicted hourly urine output at the beginning of time .	(6)
Adjusted rate	The predicted infusion rate according to mean value of lower and upper limit of the expected target urine output.	(8)
Fluid rate	The suggested infusion rate.	(9)
