Elisa Giordano Lab Make-up for Lab #1 Hypothesis: The hypothesis for this lab procedure is that my heart beat will vary between each trial. However, each result will be close to one another. General Procedures: An index finger was gently placed over the carotid artery in order to measure the rate of the pulse. Beats were counted over a 15 second interval and then recorded. Next, 15 seconds passed before measuring the results of the next trial. These steps were repeated until the results of 10 trials were recorded. The pulse rate taken seemed very high. This could be due to many possible errors discussed below. Graph: See Next Page Errors and Possible Improvements: One error that is certain is that the ‘subject’ whose pulse was taken is on medication that speeds up heart rate. It is medication used to help control Attention Deficit Disorder (ADD).

Unformatted text preview: Another possible error for the high pulse rate could be because it was not the resting heart rate. This rate could have been taken after the ‘subject’ had walked or ran up a flight of stairs. One way that these results could be better taken would be early in the morning when the subject had not yet taken any sort of medication. Conclusion: Overall, the technique on how to measure pulse was the greatest learned benefit. The hypothesis here was generally correct. The heart rate varied slightly and could have better been measured over a 60 second interval rather than a 15 second interval and then simply multiplied by four to obtain a predicted rate in beats per minute. Time Intervals (s) vs. Beats Per Minute 98 100 102 104 106 108 110 112 114 116 118 30 60 90 120 150 180 210 240 270 Time Intervals (sec) Beats Per Munite (BPM)...
