Amputation is a critical complication of ECMO, but historically one of the most difficult to anticipate. Even when it’s top of mind for care teams managing patients on VA or VV ECMO, it can be challenging to monitor and prevent. 

Even with tissue saturation measurement tools like NIRS, which are standard in many ICUs, there can be blind spots when it comes to real-time blood flow.

That’s where Transonic comes in with a complete ECMO flow solution.

Clamp On. Measure. Protect.

The AureFlo® System, paired with the Optima® Flowmeter and Transonic Flowsensors, give ECMO teams a non-invasive, easy-to-use way of monitoring blood flow through distal perfusion catheters (DPCs). As a complete solution, these tools offer real-time, beat-to-beat quantitative flow data without modifying the ECMO circuit or compromising sterility.

What makes this combination powerful:

• AureFlo delivers an integrated flow measurement experience with visual waveform data, touchscreen display and customizable sensor compatibility.
• Optima Flowmeter provides streamlined, precise measurements with dual-channel options for monitoring inflow and outflow simultaneously.
• Transonic Flowsensors, including 2XL sensors designed for 1/8" OD tubing, clamp directly onto DPC lines, making it ideal for the 50–250 mL/min flow range called for in ELSO guidelines.

This isn’t just innovation: it’s the missing link in many ECMO workflows. 

Built for Critical Care Environments

These tools are used in some of the most advanced ORs and ICUs around the world. Why? Because they’re:

1. Non-invasive: Sensors never touch the fluid, preserving sterility
2. Fast and accurate: Real-time data, even in turbulent or pulsatile flow
3. Versatile: Multiple sensor sizes available for standard tubing ODs
4. Reliable: Proven transit-time ultrasound technology, trusted for over 40 years

If your current setup relies on NIRS alone, it may be time to add the other half of the equation. With Transonic, there’s no complicated install or steep learning curve. 

No circuit modification, no sterility disruption and no guesswork. Just data, so you can:

• Avoid both ischemia and hyperperfusion
• Support compliance with ELSO’s flow monitoring guidelines
• React in the moment to save a limb and save a life
