Understanding Ventricular Pressure-Volume Catheter Calibrations and Experimental Design

Understanding Ventricular Pressure-Volume Catheter Calibrations and Experimental Design

  • 27 Nov 15

An in-depth exploration of ventricular pressure-volume catheter calibration parameters, considerations for experimental design and their effects on your pressure-volume data.

Cardiovascular researchers interested in acquiring baseline and load-independent ventricular pressure-volume data face a multitude of questions regarding technology, calibration and experimental design. Focusing on results and keeping the end in mind is often where the best answers lie.

Dr. Dimitrios “Jim” Georgakopoulos — an expert in the theory, history and application of ventricular pressure-volume science — discusses conductance-based pressure-volume technology, the theory and importance behind resistivity and parallel volume calibration factors, how experimental conditions can (and should) influence your approach and the significance of proper calibration in acquiring quality results.

Key topics covered in this webinar include…

• Ventricular pressure volume calibration theory

• Designing a PV Loop experiment with the end in mind

• Parallel volume calibration

• Resistivity or conductance calibration

• Markers for quality and reliable pressure-volume data
