Clinical Validation
accurate, precise, and extensively validated technology
Cheetah Medical’s completely noninvasive volume management system has been extensively validated for accuracy, precision and sensitivity against the pulmonary artery catheter (PAC), PICCO®, transonic and esophageal doppler.

|---|---|---|---|---|
| Waldron NH et al | Cheetah NICOM vs EDM guided goal directed fluid therapy in the perioperative space | Consistent & significant correlation of baseline SV between monitors in 234 fluid challenges. Additionally, Bioreactance had fewer missing data points (N=61) | Anesth Analg | 2014 |
| Marik PE et al | The use of bioreactance and carotid Doppler to determine volume responsiveness and blood flow redistribution following passive leg raising in hemodynamically unstable patients | PLR validated with sensitivity of 95% and specificity of 100% with Bioreactance, compared to a sensitivity of 94% and a specificity of 86% for carotid doppler | Chest | 2013 |
| Rich JD et al | Noninvasive cardiac output measurements in patients with pulmonary hypertension | Performed with more precision than Swan TD in vasodilator challenge (p<0.001), (N=20) | Eur Respir | 2013 |
| Squara P et al | Comparison of monitoring performance of Bioreactance vs. pulse contour during lung recruitment maneuvers | Bioreactance and PICCO had equivalent CO & SV monitoring capabilities, including the ability to detect directional changes in CO (N=20) | Critical Care | 2009 |
| Raval NY et al | Multicenter evaluation of noninvasive cardiac output measurement by bioreactance technique | CO measurements made simultaneously between bioreactance and TD in CCU, ICU and cardiac catheterization labs. Bioreactance results highly correlated with TD in the ICU (r=.78) (N=70) | J Clin Monit Comput | 2008 |
| Squara P et al | Noninvasive cardiac output monitoring (Cheetah NICOM): A clinical validation | Demonstrated a 93% sensitivity and 93% specificity for detecting directional changes, and correlated highly with thermodilution (r=.82) (N=110) | Intensive Care Medicine | 2007 |
| Keren H et al | Evaluation of a noninvasive continuous cardiac output monitoring system based on thoracic bioreactance | Showed high CO correlations with PAC (r=.90) in 27 patients and transonic doppler in 9 animals (r=.87) | Am J Physiol Heart Circ | 2007 |
