Automated Noninvasive Blood Pressure – Human

The NIBP100D Noninvasive Blood Pressure System automatically records noninvasive blood pressure. The NIBP100D system attaches to the fingers of a human subject to output a continuous noninvasive arterial pressure (CNAP) signal. The system will work for short and long-term studies that demand several hours of monitoring. Combine the blood pressure signal with a variety of […]

Body Composition Analysis

Although there is no direct theoretical relationship between whole body resistance and/or reactance and adiposity, empirical relationships exist to relate total body water and fat free mass (FFM) to impedance, weight, height, gender and age. In effect, lean body impedance is a function of the specific resistivity of the lean tissue, together with its cross-sectional […]

ICG Analysis

Record and analyze impedance cardiography data. Use the automated ICG analysis routine to output key measures into excel or the journal file. Use ensemble averaging to view the averaged dZ/dt signal. Following dZ-dt scoring, apply the automated ICG analysis routine to derive a wide array of impedance and hemodynamic measures, such as stroke volume, cardiac output, […]

Impedance Cardiography and Cardiac Output

Record and analyze impedance cardiography data Use automated ICG analysis to output key measures Use Ensemble Averaging to view the averaged dZ/dt signal AcqKnowledge offers a comprehensive array of noninvasive impedance cardiography (ICG) tools for recording parameters associated with virtually any kind of biological electrical bioimpedance monitoring. Extracted measures can be displayed as new channels […]

Peripheral Blood Flow

When used in conjunction with an occluding cuff, electrical bioimpedance measurements on limbs can assess arterial blood flow and venous thrombosis. To prevent venous outflow without significantly changing arterial inflow, rapidly inflate the TSD120 cuff to 40-50 mmHg. The blood inflow causes an increase in the volume of the limb. To measure the arterial flow rate, […]

Pulse Rate Measurement

The NICO100C easily measures the change in thoracic impedance that occurs as the heart beats. As blood is forced out of the aorta during ventricular ejection, the impedance through the torso drops momentarily. The derivative of this waveform (dZ/dt) can be processed to record pulse rate (BPM) on a cycle-by-cycle basis in real time. The dZ/dt […]

Respiration Monitoring

For bioimpedances measured across the thorax using the EBI100C, a small impedance change is observed with each inspiration and expiration. For respiration monitoring, electrodes are placed across the mid-thorax along the mid-axillary line. Filtering can be employed in AcqKnowledge to minimize motion artifacts. Because the EBI100C measures the thoracic impedance directly, the module can measure […]

Tissue Magnitude and Phase Modeling

The EBI100C measures tissue impedance magnitude and phase simultaneously at any of four operational frequencies (12.5, 25, 50 and 100kHz) for multi-frequency bioimpedance analysis (MFBIA). Accordingly, the EBI100C can be used to develop an electrical model of the tissue measured. Real and imaginary parts of the tissue impedance can be determined over this range of […]

Tissue Resistance and Reactance Measurement

Tissue resistance is mathematically described as the real part of the tissue impedance and tissue reactance is defined as the imaginary part of the tissue impedance. To determine these parameters, measure the impedance magnitude and phase using the EBI100C. Use the AcqKnowledge Equation Generator to multiply the magnitude by the cosine of the phase to […]

Total Peripheral Resistance (TPR)

BP = CO x TPR where BP = blood pressure CO = cardiac output TPR = total peripheral resistance To learn more about measuring TPR using BIOPAC, review these TPR citations. See Cardiovascular Hemodynamics/Cardiac Output Applications for related measurement options.
