The Integrated CardioRespiratory (ICR) System, when used with ICR Acoustic Sensors and ECG Sensor Electrodes on the chest wall, is intended for use in acquiring and analyzing heart sound data and computing and reporting an estimate of left ventricle Ejection Fraction that is comparable to that derived by 2-D echocardiography. The device is not intended for continuous monitoring of Ejection Fraction. The ICR System is not intended as a sole means of diagnosis. It does not supersede the judgment of the qualified medical personnel. The ICR System is intended to aid the physician in the evaluation of heart function. The interpretation of EF values offered by the ICR System are only significant when used in conjunction with physician over-read as well as consideration of all relevant patient data. Indicated for use in adults only. The ICR System is intended for use under the direct supervision of a licensed healthcare practitioner or personnel trained in its proper use within a hospital or facility providing healthcare.

The Integrated CardioRespiratory (ICR) System is a non-invasive skin adhering sensors and computer based device that allows for measurement of Ejection Fraction (EF). The ICR System includes four acoustic sensors and ECG electrodes that are placed on the patient's chest to collect signals, which are combined to compute the EF percentage value. The ICR System performs signal processing computation to identify and characterize amplitude and time of event characteristics of S1 and S2 heart sounds. The computed EF percentage value is presented to the clinician on the ICR Patient Monitor display. The ICR System consists of the following components: 1. ICR Acoustic Sensors 2. ECG Sensor Electrodes 3. ICR Sensor Application System 4. ICR Patient Monitor
