A respiratory therapist observes the following data while assessing a patient in the cardiac ICU.
CVP = 10 mm Hg
PCWP = 15 mm Hg
QT = 11 L/min
Urine output 100 mL/h
Based on this data, what should the respiratory therapist suspect is wrong with the patient?
- Metabolic acidosis
- These values are within normal limits
The CVP, PCWP, QT (cardiac output), and urine output are greater than normal, suggesting hypervolemia (fluid overload). Normal CVP is 2-6 mm Hg. Normal PCWP is 5-10 mm Hg. Normal urine output is about 40 ml/hour or 1 Liter/day.
