continuous, accurate, noninvasive hemodynamic monitoring to guide volume management in virtually any clinical setting
The CHEETAH NICOM and Starling SV hemodynamic systems are based on Bioreactance®, a technology that was created by the company following years of research and development and 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.
How does Cheetah’s technology work:
- Four noninvasive sensor pads are applied to the thorax, creating a ‘box’ around the heart.
- A small electric current of known frequency (75kHz) is applied across the thorax between the outer pair of sensors.
- A voltage signal is recorded between the inner pair of sensors.
- The flow of blood in the thorax introduces a time delay, or phase shift, in the signal.
- Cheetah’s proprietary algorithms interpret the signal to provide stroke volume.
- These signal changes have been correlated to known thermodilution cardiac output in 65,000 patient samples across multiple clinical settings (ICU/OR/Cath Lab).
