Product category: Patient monitoring systems / Measuring stations
The CHEETAH NICOM™ and Starling™ SV provide continuous, accurate, non-invasive hemodynamic monitoring and empower volume management in virtually any clinical setting.
They are based on Bioreactance®, a technology that was created by Cheetah Medical's scientists over years of research and development, followed by extensive testing and validation. The basis behind this technology is the use of time delay, or phase shifts, which occur when an alternating electrical current (AC) is passed through the thorax.
The unique, patented Bioreactance® technology takes measurements continuously and with extreme precision. Additionally, it requires only 4 sensors that are easily placed on the thorax. The sensors can be placed anywhere on the chest or back as long as two are positioned above and two are positioned below the heart.
It's important to note Bioreactance technology should not be confused with bioimpedance, an older technology that has certain limitations when used for assessing fluid responsiveness.

The basis behind CHEETAH NICOM are phase shifts that occur when an alternating electrical current (AC) is passed through the thorax. This should not be confused with bioimpedance, an older and less accurate technology.
How CHEETAH NICOM Works The foundation of Cheetah Medical’s CHEETAH NICOM technology is the discovery that when an AC current is applied to the thorax, the pulsatile blood flow taking place in the large thoracic arteries causes the amplitude of the applied thoracic voltage to change. In addition, it causes a time delay or Phase Shift between the applied current and the measured voltage. Extensive research has shown that these phase shifts are tightly correlated with stroke volume. By accurately and continuously measuring phase shifts, the stroke volume is determined. CHEETAH NICOM is equipped with a sensitive phase detector that can detect very small phase shifts. These phase shifts are highly correlated with the aortic blood volume and are the building blocks of the CHEETAH NICOM signal. The CHEETAH NICOM signal represents blood volume, and the derivative of the CHEETAH NICOM signal over time provides the CHEETAH NICOM signal, which represents the change of volume in time, i.e. aortic flow. The stroke volume is then measured from the CHEETAH NICOM signal.
