Like “End of diastole” and “Tau fitting options” are only available in ventricular mode, and “Dicrotic Notch” is only available in arterial mode - for obvious reasons - so are some of the calculated parameters. A complete list and description of ventricular and arterial parameters can be found in LabChart’s Help documentation under Blood Pressure > Blood Pressure Parameters.
When changing the Pressure signal from Ventricular to Arterial the following calculations are turned off:
Max dP/dt, Min dP/dt, EDP, Tau, Pressure Time index, Contractility Index and IRP Average dP/dt.
When changing the Pressure signal from Arterial to Ventricular the following calculations are turned off:
Time to Peak, Dicrotic Notch Pressure and Mean diastolic pressure.
The following calculations are converted in both directions:
|Max Pressure||Systolic Pressure|
|Min Pressure||Diastolic Pressure|
|Max-Min Pressure||Pulse Pressure|
|Systolic Duration||Ejection Duration|
|Diastolic Duration||Non-Ejection Duration|
The parameters Mean Pressure, Heart Rate and Cyclic Duration stay the same for both settings.
