Q: How much change in level of hemoglobin should necessitate adjustment on bedside monitor to obtain accurate hemodynamic data from Pulmonary Artery Catheter (PAC/Swan-Ganz Catheter)?


Answer: A change in hemoglobin of 1.8 g/dL or greater should compel change/update  in the record of hemoglobin on the bedside monitor. In any case, by default a calibration of transducers/monitor/PAC should be performed at least once every 24 hours.
