The Pressure-Volume system from Transonic Scisense uses the improved admittance measurement mode, offering an excellent measurement accuracy and absolute volume in real-time.
Indeed, nowadays, the admittance technique has outclassed historical conductance technic, by providing a continuous correction of the parallel conductance without the necessity of saline injection.
Such correction is important for accuracy in volume calculation. Indeed, by removing the parallel conductance (part of the signal going through the muscle), blood signal can be isolated and true volume is calculated and reported in real-time.
Furthermore, Phase angle is provided, allowing to locate the catheter in the ventricle.
IOX2 software is used for the complete analysis of loops either in traditional conductance or improved admittance measurement modes.
Its PV loop module offers a very efficient analysis through the following features:
