- Loops Plots Aortic Blood Flow Velocity

From

0

In collaboration with Lariboisiere Hospital Paris, Deltex Medical has developed a highly innovative method of simultaneously displaying aortic blood flow velocity and aortic blood pressure throughout every heartbeat. TrueVue™ Loops plots aortic blood flow velocity (using oesophageal Doppler ultrasound monitoring) against aortic blood pressure from a standard arterial pressure transducer. It does this in real time, 180 times per second, to create a Velocity-Pressure Loop.

Product Details

The resulting graphical representation provides the clinician with:

  • The complete haemodynamic picture in real-time
  • Unique biomarkers for early detection of hypo- and hyper-volaemia and hypo- and hyper-tension
  • Immediate reliable feedback on response to fluids, inotropes and vaso-active drugs.

Interpreting the TrueVue Loops display
Examples of what graphical output the TrueVue Loops will deliver, and what it means

  • Loop A: Hypotensive patient: low pressure, low resistance and consequent high flow velocity. At risk of AKI and/or heart failure
  • Loop B: Normal state: good flow, good pressure, good resistance. Low risk of haemodynamic compromise
  • Loop C: Hypertensive patient: high pressure, high resistance, reduced flow. At risk of stroke and/or heart failure
