A 55-year-old man on ICU is being monitored with a pulmonary artery catheter. Thermodilution cardiac output measurements are performed. The first three measurements give: 4.2, 4.5, and 8.1 L/min. What is the most appropriate interpretation?AThe cardiac output is 5.6 L/min (average of all three)BThe 8.1 L/min reading is an outlier, likely from injection during the respiratory cycle or tricuspid regurgitation; discard it and average the two concordant values (4.35 L/min)CThe cardiac output is 8.1 L/min - the highest reading is most accurateDAll readings are inaccurate and the catheter should be replacedEThe variability indicates severe cardiac dysfunctionCheck my answer
