INTRODUCTION
The BioZ is an innovative noninvasive impedance cardiography (ICG) device that provides
hemodynamic parameters based on the measurement of thoracic electrical bioimpedance. Specifically,
the BioZ allows for assessment of a patients hemodynamic status and ventricular function by
determining twelve (12) hemodynamic parameters as well as four (4) indexed parameters. In addition,
the BioZ allows the operator to:
Observe trends in the patients status
Measure Blood Pressure Independently with Optional integrated Blood Pressure monitor
View, store, and review the collected data and/or waveforms
Print reports of the hemodynamic parameters with the date and time annotated accordingly
Copy/Download files to a PC
Utilize security precautions Password protection for system configuration
SYSTEM FEATURES
3.1 Standard Features
The BioZ interfaces with:
The BioZ measures the following parameters:
-
Thoracic Fluid Content (TFC): the inverse of the thoracic base impedance
-
Indices of Contractility: reported as Acceleration Index (ACI) and Velocity Index (VI)
-
Pre-Ejection Period (PEP)
-
Left Ventricular Ejection Time (LVET)
-
Heart Rate (HR)
-
Blood Pressure (if optional module purchased)
-
The BioZ calculates the following parameters:
-
Cardiac Output (CO)
-
Stroke Volume (SV)
-
Systemic Vascular Resistance (SVR): also reported as Afterload
-
Left Cardiac Work (LCW)
-
Systolic Time Ratio (STR)
-
Several of the above parameters are indexed with reference to body surface area (BSA) to give indexed
-
parameters. The BioZ calculates the following indexed parameters:
-
Cardiac Index (CI)
-
Stroke Index (SI)
-
Systemic Vascular Resistance Index (SVRI)
-
Left Cardiac Work Index (LCWI)
