PV Loop module for LabChart

Features

Loop View

  • Choose which PV loops to analyze
  • Contractility index using ESPVR slope (linear or quadratic)
  • Compliance index using EDPVR slope (linear or exponential)

Industry standard parameters

  • Stroke Work, Cardiac Output, Ejection Fraction, Tau Isovolumic Relaxation Constant, and many more
  • Available from the Haemodynamics Table, with support for exporting to LabChart DataPad, or csv/text files for analysis

Analysis plots

  • Preload-recruitable stroke work (PRSW)
  • Preload-recruitable maximum pressure change (dP/dt Max vs. EDV)
  • Preload-recruitable maximum pressure change (dP/dt Max vs. EDV)
  • Preload-recruitable total mechanical work (PVA vs. EDV)
  • Afterload-dependent total mechanical work (PVA vs. ESP)

Streamlined workflow

PV Loop 2 guides your journey from pressure, conductance and volume calibration through to data analysis with its mapped, new Workflow mode.

Intelligent presets

Preset calibrations for small and large mammals enable you to follow best practices for recording and analyzing PV data using Millar catheters. The Workflow modes are optimized for use with Millar's MPVS Ultra or MPVS 300/400 systems.

Powerful volume calibration

PV Loop 2 also supports the analysis of multiple averaged cuvette well readings for accurate conductance to volume calibration.
Parallel Conductance Averaging

Correcting for parallel conductance from multiple saline bolus infusions doesn't need to be difficult. You can now generate a Ves Ved regression curve using averaged data to give you a reliable estimate.

Advanced calibration

Alpha calibration is supported for researchers validating ventricular derived cardiac output with an independent measure, e.g., using a Transonic flow probe.

Compatibility

  • LabChart 8 for Windows
