Figure 2: Mean cumulative fluid overload over the first 5 days of emergent intensive care unit stay (longer length of mechanical ventilator group vs. shorter mechanical ventilator group). X-axis represents the days 1–5 for patients admitted to the hospital. The y-axis is the mean cumulative fluid overload per day in each group in the first 5 days of emergent intensive care unit stay. Mean cumulative fluid overload of longer length of mechanical ventilator group becomes significantly higher than those of shorter mechanical ventilator group on day 2
