Clinical Need

Millions of patients are admitted to ICUs in the U.S. every year. Stroke volume and cardiac output are key hemodynamic indicators of efficacious therapeutic management in the ICU. Noninvasive continuous measurements of stroke volume and cardiac output are indispensable to optimize fluid management, which enhances patient recovery for safe and effective hospital discharge.

Current Practices

Current gold standard is the thermodilution method using the Swan-Ganz catheter, which is an invasive and expensive procedure with intermittent measurements. Noninvasive continuous measurement techniques using pulse wave analysis and bioimpedance have been introduced as surrogates, but their clinical acceptance is limited mainly due to poor accuracy.


BiLab provides a method to quantify how much blood is pumped out of the heart. Using a multi-channel impedance plesthysmography technology, noninvasive continuous bedside monitoring of cardiac blood flow is possible. Capturing fast changes in cardiac blood flow using electrode pads around the chest, stroke volume and cardiac output signals are acquired. Beat-to-beat measurements of stroke volume can facilitate the fluid challenge, passive leg rasing, and end-expiratory occlusion tests to determine preload responsiveness. The noninvasive device can continuously monitor stroke volume and other hemodynamic parameters throught the entire fluid management process.
