Noninvasive impedance cardiography (ICG) tools
AcqKnowledge® offers a comprehensive array of noninvasive impedance cardiography (ICG) tools for recording parameters associated with virtually any kind of electrical bioimpedance (EBI) monitoring and bioimpedance analysis (BIA). Extracted measures can be displayed as new channels in the recording, or exported to an Excel spreadsheet or Journal file for further analysis. In addition to conventional BIOPAC® data acquisition hardware, record wirelessly with the BioNomadix® BN-NICO system.

Noninvasive BP Integrated System
Wired | ICG: Impedance Cardiography/Cardiac Output
NIBP100E noninvasive blood pressure system provides continuous, beat‐to‐beat, blood pressure signal and values (Sys, Dia, MAP) and Pulse Rate (PR). The system includes NIBP amplifier, double-finger cuffs, arm cuffs, CNAP Controller, and required hoses/cables. The system outputs a continuous blood pressure waveform that is similar to a direct arterial pressure waveform. The amplifier provides values for systolic, diastolic, mean blood pressure, and heart rate. The NIBP100E amplifier with CNAP™ technology is controlled by AcqKnowledge (v5.0.7) Research Software and connects to MP160 and MP150 data acquisition modules. To add hemodynamic parameters CO, CI, SV,SI, SVR, and SVRI, request NIBP100E-HD.

Impedance Cardiography Parameters
dZ-dt Classifier – AcqKnowledge® automatically scores the dZ/dt waveform with event markers indicating appropriate points in the complex to derive additional measures. For a detailed demo, see the ICG dZ-dt Classifier Tutorial Video.
ICG Analysis – Following dZ-dt scoring, apply the automated ICG analysis routine to derive a wide array of impedance and hemodynamic measures, such as pre-ejection period, stroke volume, cardiac output, heart rate, R-R interval, and more. Individual measures can be toggled on or off, allowing a customized subset of measurement data to be included in the output.
Full list of measures extracted by ICG Analysis:Acceleration Index (AI) Cardiac Index (CI) Cardiac Output (CO) Heart Rate (HR) Left Cardiac Work (LCW) Left Cardiac Work Index (LCWI) Left Ventricular Ejection Time (LVET) Pre-ejection Period (PEP) RR Interval (RR) Stroke Index (SI) Stroke Volume (SV) Systemic Vascular Resistance (SVR) or Total Peripheral Resistance (TPR) Systemic Vascular Resistance Index (SVRI) Systolic Time Ratio (STR) Thoracic Fluid Content (TFC) Thoracic Fluid Index (TFI) Velocity Index (VI) Mean BP (requires additional signal) Mean CVP (requires additional signal) Mean PAP (requires additional signal)
