The CCOmbo volumetrics catheter, pioneered as the first catheter to offer continuous RVEDV and RVEF measurement, provides the clearest possible picture of hemodynamic performance. -Continuous Cardiac Output (CCO). -Right Ventricular End Diastolic Volume (RVEDV). -Right Ventricular Ejection Fraction (RVEF). -Mixed Venous Oxygen Saturation (SvO2). -The CCOmbo V catheter, when used in conjunction with the Vigilance monitor, uses the latest in thermodilution and pseudorandom sequencing technologies, enabling clinicians to assess EDV and other volume measurements accurately. -A more reliable indicator of preload than current pressure-based measurements. -Accurately measures right-side volumes. -Provides greater reproducibility, avoiding inconsistencies associated with bolus measurements.
