Objective: The purpose of this experiment was to measure pulse and heart rate by using a BIOPAC MP30 ECG system with electrode leads and a pulse transducer. The electrode leads provided a means for measuring heart rate while the pulse transducer allowed for pulse rate measurement. Thus a secondary objective was to learn and understand the computer simulated ECG and its components as they pertain to heart rate and pulse rate. Materials: MP30 BIOPAC System Meter stick Adhesive electrode pads Electrode sensors Finger pulse sensor Computer Lab manual Bucket of Ice Humans Methods: 1. Hook Up The Subject Plug the electrode lead into channel 1 and the pulse transducer into channel 2 Turn on the MP30 data acquisition unit Place one electrode on the medial surface of the right and left leg, just above the anklebone, and one electrode on the right anterior forearm just above the wrist. Attach the three pinch connectors a the end of the electrode cables to the specific electrodes: Black on right leg, Red on left leg and White on right forearm

Position the electrode cables such that they are not pulling on the electrodes of the transducer. Position the transducer so that the sensor is on the bottom of your fingertip and wrap the Velcro tape around your finger so the transducer fits snuggly. Have the subject sit down with forearms supported and relax. Subject should be relaxed and motionless. 2. Calibrate and Take Resting Values The calibration button is in the upper left corner of the setup window. Press the button to start the calibration recording making sure the subject is relaxed and motionless. The calibration will stop automatically after 8 seconds. At the end of the 8-sec calibration recording, the screen should resemble Fig. 7.6 on page 9 of your lab manual. If it does not then hit the Redo calibration button and try again.
