Several factors cause bubbles to change shape as they travel through the circulatory system or extracorporeal tubing.
Bubbles often travel in formations or “swarms” making it difficult to distinguish between one bubble and multiple bubbles. This can result in false positives in cases where the smaller-sized bubbles are not intended to be detected.
Orientation can impact a sensor’s ability to detect bubbles. The direction or angle of the ultrasound signals will determine which cross-sectional area of the bubble is being measured, and as a result, can make a bubble’s diameter appear larger or smaller.
Transonic engineers are experts at overcoming sensing challenges. With over 4 decades of experience across dozens of biomedical and research applications, we’ve developed extensive bubble detection know-how.
The same attributes that produce superior flow measurement also yield highly accurate bubble detection. Having an integrated Transonic Flowboard means that the flow measurement system can be custom calibrated for specific flow conditions.
Transonic bubble detection systems can measure over a wide range of flow rates and perform well with pulsatile and turbulent flows.
