Waveforms & measurements
Every pressure channel, scales, annotations and the summary table.
What are the a, c, x, x′, v and y features?
Use the paused atrial/wedge trace to connect atrial activity with valve and filling events.
What does the pleth waveform represent?
A modeled pulsatile perfusion signal displayed with SpO₂ and respiration.
What happens when I press Pause?
Freeze the monitor and reveal detailed teaching tools.
Where can I find normal reference values?
Use Normal reference values beneath the hemodynamic summary.
Where is LVEDP shown, and why is it different from LV Dia?
LVEDP is listed separately in the summary and identified on the pullback.
Where is the restriction-versus-constriction comparison?
Select one of those conditions and pause with the pullback visible.
Where is the simultaneous femoral artery comparison?
Select severe AS and enable the pullback’s femoral comparison.
Why are aortic and arterial-line pressures different?
The peripheral pulse is slightly delayed and amplified.
Why are pressures rounded, and how precise are the calculations?
Whole-number pressures keep the displays clear; calculations retain decimal precision.
Why can PAWP, PADP and LVEDP differ?
They describe different sites and different parts of the pressure cycle.
Why can the summary CO, Fick and thermodilution differ?
The summary is modeled forward flow; the measurement panels include method assumptions.
Why do summary numbers become crimson and bolder?
Numbers move gradually from black to crimson and gain weight as abnormality increases.
Why does each pressure tracing have its own scale?
Dynamic vertical scales keep the full waveform visible.
