Brief summary
Daily Fluid Balance vs Weight Change
Detailed description
The daily fluid balance will be compared to 24hour weight change in critical care patients. The design will be prospective observational study. The data will be gathered using Linet automatic built in weight in Linet beds and for fluid balance will be used standard nurse charting method. The main outcome will be limit of agreement between daily fluid change and 24hour weight change.
Interventions
OTHERDaily Weight and fluid balance change
In all enrolled patients, both 24-hour body weight change and cumulative 24-hour net fluid balance will be assessed over identical 24-hour intervals by nursing personnel. Fluid balance will be recorded using a standardized 24-hour fluid balance chart and calculated as the difference between total fluid intake and urine output and fluid output to drains. Body weight measurement will be performed once daily. Body weight will be measured using the integrated weighing system of the ICU bed.

Exclusion criteria
* age \<18 years * pregnancy * inability to obtain standardized daily body weight using the ICU bed scale * incomplete 24-hour fluid balance data preventing calculation of cumulative balance * absence of an indwelling urinary catheter, extracorporeal life support (ECMO) or other extracorporeal circulation * open abdomen * open chest * lavage or irrigation procedures during the assessment interval * surgery during the assessment * massive bleeding * diarrhoea during the assessment period * massive transfusion protocol during the 24-hour interval and ICU stay shorter than 24 hours.
