Pulse Pressure Waveform Analysis (PPWA)
Introducing TrueVue™ PressureWave™
TrueVue™ PressureWave™ uses the most stable and extensively researched Pulse Pressure Waveform Analysis (PPWA) algorithm, as proposed by Liljestrand and Zander. Peer-reviewed clinical investigations support it as a quantitative estimator of Cardiac Output. The PPWA mode is useful during periods of instability or for periods when the ODM mode is unavailable. The highly sensitive “Flow Monitoring Mode” guides intervention, combined with the simpler “Pressure Monitoring Mode” for extended continuous monitoring.
Deltex’s TrueVue platform uniquely enables the user to switch between Pressure and Flow Mode. This means the PressureWave signal for continuous monitoring can be simply calibrated against the gold standard ODM waveform.
The resulting, accurately calibrated PPWA mode is beneficial in postoperative and medical patients in critical care who may not tolerate an indwelling ODM+ probe. The PPWA algorithm can be recalibrated at any time from the Doppler waveform in sedated patients.
