Indications for Use
The Cheetah Reliant with NIBP functionality is a portable, non-invasive Cardiac Output monitoring device that monitors and displays a patient' Cardiac Output (CO) in Ltr/Min with a non-invasive blood pressure function that non-invasively measures and displays blood pressure (diastolic, systolic, and mean). In addition, the device measures and displays associated hemodynamic parameters based on calculations of measurements already incorporated into the Cheetah Reliant. These parameters are: Cardiac Index (CI), Ventricular Ejection Time (VET), Total Peripheral Resistance Index (TPRI), Stroke Volume Index (SVI), Stroke Volume Variation (SVV), Cardiac Power (CP), Cardiac Power Index (CPI) and Thoracic Fluid Content (TFC). The Cheetah Reliant with NIBP functionality is intended for use within hospitals and other healthcare facilities (e.g., outpatient clinics) that provide patient care. The alternative NICOM Sensors are disposable electrodes used in conjunction with the Cheetah Medical NICOM signal processing product line.
Device Story
Cheetah NICOM System is a portable, non-invasive cardiac output (CO) monitor; utilizes electrical bioimpedance/bioreactance technology. System inputs: electrical signals from disposable NICOM sensor array placed on thorax; high-frequency sine wave injected into body; voltage measured at adjacent electrodes. Processing: calculates impedance to current flow; constructs electrical bio-reactance waveform; derives CO and hemodynamic parameters (CI, VET, TPRI, SVI, SVV, CP, CPI, TFC). Output: real-time display of CO, blood pressure, and hemodynamic indices. Used in hospitals/clinics by healthcare providers to assess patient hemodynamic status; aids clinical decision-making regarding fluid management and cardiovascular therapy. Benefits: provides continuous, non-invasive hemodynamic monitoring without risks associated with invasive catheters.
Clinical Evidence
Clinical testing performed on 15 patients undergoing cardiac output evaluation. Compared alternative NICOM sensors against previously cleared NICOM electrodes. Data demonstrated substantial equivalence in performance.
Technological Characteristics
Non-invasive electrical bioimpedance/bioreactance monitoring. Disposable double-electrode stickers. Standards: AAMI/ANSI EC12:2000/(R)2005, EC53:1995/1998, IEC 60601-1, ASTM F640, ISO 10993-1/5/10. System includes signal processing unit for waveform construction and hemodynamic calculation.
Indications for Use
Indicated for patients requiring non-invasive cardiac output and hemodynamic monitoring in hospital or outpatient clinical settings. No specific age or gender contraindications stated.
Regulatory Classification
Identification
A single-function, preprogrammed diagnostic computer is a hard-wired computer that calculates a specific physiological or blood-flow parameter based on information obtained from one or more electrodes, transducers, or measuring devices.

#### Device Description:
The Cheetah Reliant non-invasive CO monitor (NICOM) is a portable, non-invasive, Cardiac Output detector system. The NICOM system measures the Cardiac Output by employing the electrical bioimpedance measurement technique. Electrical bio-impedance is the characteristic impedance of a volume of tissue and fluid. In the case of Cardiac Output measurements, the relevant tissue includes the heart and the immediate surrounding volume of the thorax. The relevant fluid is blood.
Cheetah Medical's alternative NICOM Sensor is a double electrode sticker. Within each sticker, one electrode is used to inject the a high frequency sine wave into the body, while the resulting voltage is measured at the adjacent electrode. An array of such electrodes is placed at specific areas of the thorax, the impedance to the current flow calculated, and finally the electrical bio-reactance waveform constructed.
#### Indication for Use:
The Cheetah Reliant with NIBP functionality is a portable, noninvasive Cardiac Output monitoring device that monitors and displays a patient' Cardiac Output (CO) in Ltr/Min with a non-invasive blood pressure function that non-invasively measures and displays blood pressure (diastolic, systolic, and mean). In addition, the device measures and displays associated hemodynamic parameters based on calculations of measurements already incorporated into the Cheetah Reliant.

## Brief Description of Clinical Testing
The alternative NICOM Electrodes were tested on 15 patients who underwent cardiac output evaluation at Cheetah-Medical Ltd. with the alternative NICOM sensors and the NICOM electrodes cleared for use with the Reliant System.
The data demonstrated that the alternative NICOM Sensors are substantially equivalent to the NICOM electrodes cleared for use with the Reliant System.
## Conclusion
The alternative NICOM Sensors manufactured by INTEGRAL PROCESS / Conflans Sainte Honorine, France for Cheetah Medical were extensively tested (bench and clinical) and shown to be substantially equivalent to the NICOM electrodes cleared under K071631 and with K08209
