LabScribe Pressure Volume Loop Module
LS-PVL iWorx Pressure Volume Loop Software Module is a plug-in software module for iWorx data acquisition systems that performs pressure volume loop analysis for hemodynamic research in animals. The software module provides a powerful and easy to use tool for investigators to measure and analyze the hemodynamic parameters of cardiac and pulmonary pressure and volume data acquired by an iWorx recorder. Cardiac cycle parameters that can be monitored online are:- Heart Rate,
- End Systolic Pressure,
- End Diastolic Pressure,
- Max Pressure,
- Min Pressure,
- Max dP/dt,
- Min dP/dt,
- Max Volume,
- Min Volume,
- End Systolic Volume,
- End Diastolic Volume,
- Stroke Volume,
- Cardiac Output,
- Ejection Fraction,
- Stroke Work
