Slower CCO response in this sheep model suggests caution interpreting rapid changes; leaves open human validation before clinical monitoring implications.
Does a continuous cardiac output pulmonary artery catheter have a slower response time compared to an ultrasonic flow probe in detecting rapid hemodynamic changes in a sheep model?
Continuous cardiac output pulmonary artery catheters have clinically significant time delays in detecting rapid hemodynamic changes, which must be considered in critical care settings.
Siegel et al. (1996) studied this question.
