Biopac Student Lab Biofeedback

This lesson demonstrates the principles of biofeedback training for relaxation purposes. The student will record and view ECG, heart rate, and electrodermal activity (EDA). Subjects control the position of a vertical bar graph by influencing their heart rate and EDA. As heart rate increases, the bar moves up; if the heart beats slower, the bar moves down. A separate bar moves up as EDA increases and down as EDA decreases.

Experimental Objectives

  1. Introduce the concept of biofeedback training for relaxation.

  2. Measure levels of arousal via heart rate and electrodermal activity.

Tasks Performed by the Student

BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.

Noninvasive Blood Pressure Amplifier

The NIBP100E noninvasive blood pressure system provides continuous, beat‐to‐beat, blood pressure signal and values (Sys, Dia, MAP) and Pulse Rate (PR)*.  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™ […]
