Background:
PulseCO for continuous cardiac output measurement is a relatively noninvasive and effective monitor. PulseCO is obtained from the arterial pulse waveform, but calibration by another method is necessary. We performed calibration of PulseCO by CO measurement using TEE and examined the utility of PulseCO.
Methods:
PulseCO was calibrated by TEE after induction of anesthesia, and PulseCO and continuous cardiac output with Vigilance (CCO) were measured continuously. Records were obtained every thirty minutes and were excluded from analysis when hemodynamics was unstable.
Results:
Correlations of CCO with TEE (r = 0.88) and PulseCO (r = 0.86) were examined. PulseCO showed a significantly better correlation with CCO, and dispersion was small.
Conclusions:
The results suggest that PulseCO is very useful as an intraoperative cardiac output measurement monitor.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls between...

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
