PV Loop Module for Windows

Overview:

The PV Loop Module for LabChart records and analyzes left ventricular pressure and volume data for hemodynamic research in animals.  Analyses can be conducted during or after sampling.

The module allows conversion of data to absolute volumes using cuvette calibration and correcting for parallel conductance using saline calibration - all in one data file.

The PV Loop Module should be used with the latest version of LabChart.

The PV Loop Module is also available as part of LabChart Pro. The LabChart Pro software package includes all LabChart Modules.  Existing LabChart users and PowerLab system purchasers can upgrade to LabChart Pro at a special price.  For more information please contact your representative.

Sample Applications:

The PV Loop Module provides a way to analyze pressure volume loops for hemodynamic research in animals.

Typical applications:

• Baseline P-V loop analysis
• Occlusion P-V loop analysis
• Phenotyping gene manipulations
• Cardiac hypertrophy
• Cardiac failure
• Cardiovascular remodeling
• Toxicology
• Pharmacology (rapid drug screening)
• Cardiac resynchronization therapy
• Surgical interventions
• Ischemia/reperfusion studies

Features & Benefits:

• Loop view
• Examine individual loops.
• Select or exclude loops from analysis.
• Calculate and display End-systolic and end-diastolic PV relationships.
• Choose linear, quadratic or exponential regression fits for the ESPVR and EVDPR.
• The Hemodynamics Table
• A wide range of hemodynamic parameters are calculated and displayed on a loop-by-loop basis.
• Choose which parameters are displayed in the table.
• Calibration:
• Cuvette calibration can be computed and applied to the volume channel; settings files with known volumes of common cuvettes are supplied.
• Saline calibration allows the parallel volume correction factor to be calculated and applied to the volume channel.
• Plots and linear regression information can be displayed for:
• preload-recruitable stroke work (PRSW).
• dP/dt max vs EDV.
• PVA vs EDV.
• PVA vs ESP
• Use the Analysis Manager to analyze separate data regions within a data file, and save and recall the settings of each analysis for easy comparison of results.
  
  
• PV Loop data can be exported from the Data Pad as *.xls, *.txt or *.csv files.
  
  
• Synchronize PV Loop with Movie View and play PV Loop data alongside video.
