Intended Use

The Cheetah NICOM system is a portable, non-invasive Cardiac Output monitoring device based on bio-impedance Cardiography. The Cheetah NICOM system is intended to monitor and display a patient's Cardiac Output in units of Ltr/Min, and was cleared under K042144. NICOM Electrodes are disposable electrodes used in conjunction with the NICOM signal processing product line.

Device Story

Cheetah NICOM is a portable, non-invasive cardiac output monitoring system. It utilizes electrical bio-impedance measurement; a high-frequency sine wave is injected into the thorax via disposable dual-electrode stickers; voltage is measured at adjacent electrodes. The system calculates impedance to current flow and constructs an electrical bio-reactance waveform to determine cardiac output. Used in clinical settings by healthcare providers to monitor hemodynamic status. Output is displayed in L/min, assisting clinicians in hemodynamic decision-making and patient management.

Clinical Evidence

Clinical testing included: 1) 119 post-cardiac surgery patients requiring PAC; 2) 36 patients undergoing stress testing; 3) Comparative study of 10 subjects using NICOM electrodes vs. 3M Red Dot electrodes. No adverse events reported. Results confirmed substantial equivalence of NICOM electrodes to 3M Red Dot electrodes.

Technological Characteristics

Portable non-invasive cardiac output monitor. Uses electrical bio-impedance/bio-reactance. Employs disposable dual-electrode stickers. Bench testing per ANSI/AAMI EC12:2000/(R)2005. Biocompatibility per ISO-10993. Signal processing product line.

Indications for Use

Indicated for monitoring and displaying cardiac output (L/min) in patients via non-invasive bio-impedance cardiography. Prescription use only.

Regulatory Classification

Identification

Image /page/1/Picture/3 description: The image is mostly black with some white noise on the left side. The white noise appears to be concentrated on the left side of the image, gradually fading into the black background. The black background is uniform and covers most of the image. The image has a grainy texture.

### Devices to which substantial equivalence is claimed:

The Cheetah NICOM system was found substantially equivalent to the VLIGILANCE CCO/CEDV 7 VIGILANCE CCO/SVO2/CEDV Monitor (K000664) under K042144.

The NICOM Electrodes are substantially equivalent to the electrodes cleared for marketing with the original NICOM Monitoring System (K042144), when used with the NICOM system. The electrodes cleared in the original submission were the Red Dot™ electrodes by 3M Health Care.

#### Device Description:

The Cheetah NICOM is a portable, non-invasive, Cardiac Output detector system. The NICOM system measures the Cardiac Output by employing the electrical bio-impedance 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 NICOM electrode is a double electrode sticker. Within each sticker, one electrode is used to inject 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 the electrical bio-reactance waveform constructed.

#### Indications for Use:

The Cheetah NICOM system is a portable, non-invasive Cardiac Output monitoring device based on bio-impedance Cardiography. The Cheetah NICOM system is intended to monitor and display a patient's Cardiac Output in units of Ltr/Min, and was cleared under K042144.

NICOM Electrodes are disposable electrodes used in conjuction with he NICOM signal processing product line.

#### Brief Description of Non-Clinical Testing

- 1. Electrodes were tested per ANSI/AAMI EC12:2000/(R)2005; Disposable ECG electrodes, 3ed.
- 2. Biocompatibility was confirmed per ISO-10993 standard; Biological Evaluation of Medical Devices.

Image /page/2/Picture/3 description: The image is a black and white gradient. The left side of the image is white, and the right side is black. The gradient is smooth, and there are no sharp edges. The image is simple and abstract.

### Brief Description of Clinical Testing

NICOM Electrodes were tested on:

- 1. 119 consecutive patients requiring PAC in the immediate postoperative period following cardiac surgery - No adverse events were reported.
- 2. 36 patients undergoing cardiac output evaluation during stress testing in Lonestar Heart Center, Amarillo, Texas, US. No adverse events were reported.
- 3. Cardiac output was measured in 10 subjects with the NICOM System using the NICOM electrodes and using the 3M Health Care Red Dot electrodes. The results demonstrate that the NICOM electrodes are substantially equivalent to the 3M Health Care Red Dot electrodes when used with the NICOM System.

#### Conclusion

The NICOM Electrode is a dual electrode sticker, used in conjunction with its NICOM system to monitor cardiac output by measuring electrical impedance changes in the thorax region. The Cheetah NICOM system is intended for prescription use only.

NICOM electrodes were extensively tested (bench, animal, clinical) and proved to be safe and effective.

The data demonstrate that the NICOM electrodes are substantially equivalent to the 3M Red Dot Electrodes that were cleared with the original NICOM System (K042144) when used with the NICOM system.
