75bpm) because the heart does not have enough oxygen to transport throughout the body. After the person recovers from apnea the heart rate should gradually increase and reach to the normal resting heart rate (75bpm). Lastly, when the person is at resting the RSA prominence change should be small, since the heart rate should be steady and stable. However, during deep inhalation or apnea, the RSA prominence change should be bigger, due to sudden changes in heart rates. During our experiment, we used the iWorx and Labscribe on the computer to measure theindividual’s heart rate. Before one of my lab partner started to breath in to the spirometer or airflow tube, we waited for 30 second for the machine to generate a baseline; after the 30 seconds, my lab partner started to breath normally trying not to move or talk. The person continued to breath normally until we see at least three normal heart rate, pulse, air flow and lung
