Edwards FloTrac sensor and Vigileo monitor: easy, accurate, reliable cardiac output assessment using the arterial pulse
The results of the present study also show that only one of the arterial pulse
wave velocities ([PWV.

in health and disease.
07), which is improved when compared with the first version (5), uses an analysis of peripheral arterial pulse
waves to calculate CO, averaging 20-second windows over two minutes.
It has been hypothesised that the increase in PEEP and the subsequent increase in intrathoracic pressure and reduced cardiac output may cause a dampening of the arterial pulse
wave, such that the sensor has difficulty determining an arterial wave from a venous wave.
Also dynamic indices, such as respiratory variations in arterial pulse
pressure, inferior vena cava diameter, superior vena cava diameter and stroke volume, present significant limitations, are invasive and often operator-dependent.

Study results showed that ALT-711 treatment also resulted in significantly reduced arterial pulse
pressure, defined as the difference between systolic blood pressure (the upper number) and diastolic blood pressure (the lower number).
Radical also debuts Signal IQ(TM), a unique visual indication that identifies the arterial pulse
and quality of the acquired signal even under conditions of motion and low perfusion.
Study results show that patients who received ALT-711 experienced a statistically significant reduction in the arterial pulse
pressure, defined by the difference between systolic and diastolic blood pressures.
V3 also features Signal IQ, a unique visual indication, which displays the acquired signal quality and the timing of the arterial pulse
even under motion and low perfusion.
Hypertension Diagnostics has developed proprietary cardiovascular profiling technology that analyzes non-invasively derived arterial pulse
pressure waveform data as a means of providing hemodynamic parameters that are useful in assessing the cardiovascular system.
