## Indications for use
The Cheetah Reliant with NIBP and SpO2 functionalities is a portable, hemodynamic monitoring and non-invasive Cardiac Output monitoring device that monitors and displays a patient' Cardiac Output (CO) in Ltr/Min with a Non Invasive Blood Pressure (NIBP) function that non-invasively measures and displays blood pressure (diastolic, systolic and mean arterial pressure) and heart rate and with a SpO2 function that non-invasively measures and displays blood oxygen saturation (SpO2). The device displays associated heamodynamic parameters based on calculations with measurements incorporated into the Cheetah Reliant. These parameters are: * Cardiac Index (CI), * Stroke Volume (SV), * Stroke Volume Index (SVI), * Stroke Volume Variation (SVV), * Heart Rate (HR), * Ventricular Ejection Time (VET), * Total Peripheral Resistance (TPR), * Total Peripheral Resistance Index (TPRI), * Cardiac Power (Cr), *Cardiac Power Index (CP1), * Oxygen Delivery Index (D021), * Electrical impedance of the chest cavity (ZO), *Thoracic Fluid Content (TEC) * Thoracic Fluid Content change from preset time period (TFCdO and * Thoracic Fluid Content from baseline (TFCdO). * Orthostatic Bioreactance (Postural changes in SV, CO and other hemodynaniic parameters which are derived by Bioreactance) The Cheetah Reliant with NIEP and SpO2 functionalities is intended for use within hospitals and other healthcare facilities (e.g., outpatient clinics) that provide patient care.
