H21 Impedance Cardiography

This BSL PRO lesson describes hardware and software setup of the BSL System to record ECG, Impedance (Z0), and Derivative Impedance (dZ/dt), and measure relative differences in Cardiac Output and Stroke Volume using a noninvasive bioimpedance technique.

The Lesson Procedure for BSL 4.0.1 or above includes an extensively updated physiological introduction that covers Cardiac Output as a Function of Stroke Volume and Heart Rate, Cardiac Output as Related to Mean Arterial Pressure and Peripheral Resistance, How to Determine Cardiac Output, Principles of Impedance Cardiography (ICG), and Ideas for eliciting cardiovascular responses through physical maneuvers and psychological tasks.

Suggested reading: Methodological Guidelines for Impedance Cardiography , PSYCHOPHYSIOLOGY, Vol. 27, No. 1.

Experimental Objectives

For BSL 4.0.1 or above:

  1. Learn impedance cardiography techniques.
  2. Measure the change in cardiovascular responses—Stroke Volume (SV), Cardiac Output (CO), and Heart Rate (HR)—to postural changes (supine vs. standing).
  3. Examine how HR and SV interact to maintain CO.
  4. Experiment with other ways to elicit cardiovascular responses (active learning).

For BSL 4.0.0 or below:

  1. Obtain stroke volume data.
  2. Obtain cardiac output data.
  3. Correlate heart valve opening/closing with cardiac output.

Tasks Performed by the Student

BSL 4.0.1 or above: Record Subject in the supine position then in standing position.
BSL 4.0.0 or below: Subject will sit, stand, and lie down.

Space Flight Simulations Prevent Disasters Under psychological and physical stress, astronauts can put their  mission and crew in danger. Looking into this issue, researchers created a potentially catastrophic spaceflight simulation using a virtual reality environment and recorded the heart rate of participants. Psychophysiological responses to the potentially disastrous flight simulation were recorded using a BIOPAC MP […]
