a. 2. a. b. 4 Factors Influencing the Rate and Depth of Respiration You do not need to print this sheet. Read the complete directions for each numbered activity before beginning the activity. Place your observations analysis on a separate sheet. You might like to have a partner for this activity. 1. Have the subject breathe normally for 2 minutes Estimate the breathing rate (breaths per minute). b. Observe the depth of breathing during the 2 minutes of normal (quiet) breathing Have the subject breathe normally for 2 minutes, then inhale deeply. Have the subject hold his or her breath for as long as he or she can. How long in seconds was the breath-holding interval? Did the subject have the urge to inspire or expire during breath holding? 3. Have the subject breathe normally for 2 minutes, then inhale deeply. Immediately after taking the deep breath, exhale completely and forcefully. Have the subject hold his or her breath for as long as he or she can. a. How long in seconds was the breath-holding interval? b. Did the subject have the urge to inspire or expire during breath holding? Explain the difference, if any, in results breath-holding interval and breathing urge between experiment 2 and 3 using your knowledge of physiology. (The vagus nerve is the sensory nerve of the lungs, Its relayed information can help explain some of these results.) Have the subject hyperventilate (breathe deeply and forcefully at the rate of 1 breath per 4 seconds) for about 30 seconds. (Note: It is best to do this activity in a seated position. A sensation of dizziness may develop.) Immediately after hyperventilation, the subject is to hold his or her breath as long as he or she can. How long in seconds was the breath-holding interval? b. Explain the difference, if any, in the breath-holding interval results between experiment 2 and 5 using your knowledge of physiology. Have the subject breathe into a paper bag for 3 minutes. (Note: During the 3 minute period, observe the subject carefully for any adverse reactions) Describe any changes observed in breathing rate and depth of breathing between the 2 minutes of normal breathing in experiment and the 3 minutes of “paper bag breathing during experiment 6. b. Explain the difference, if any, in breathing rate and depth results between experiment 1 and 6 using your knowledge of physiology 7. Have the subject run in place, or other vigorous exercise, for 2 minutes. After running in place, the subject is to hold his or her breath as long as he or she can. How long in seconds was the breath-holding interval? b. Explain the difference, if any, in results between experiment 2 and 7 using your knowledge of physiology 6. 5. a. 6. Have the subject hyperventilate (breathe deeply and forcefully at the rate of 1 breath per 4 seconds) for about 30 seconds. (Note: It is best to do this activity in a seated position. A sensation of dizziness may develop.) Immediately after hyperventilation, the subject is to hold his or her breath as long as he or she can. How long in seconds was the breath-holding interval? b. Explain the difference, if any, in the breath-holding interval results between experiment 2 and 5 using your knowledge of physiology. Have the subject breathe into a paper bag for 3 minutes. (Note: During the 3 minute period, observe the subject carefully for any adverse reactions.) Describe any changes observed in breathing rate and depth of breathing between the 2 minutes of normal breathing in experiment 1 and the 3 minutes of “paper bag breathing” during experiment 6. Explain the difference, if any, in breathing rate and depth results between experiment 1 and 6 using your knowledge of physiology Have the subject run in place, or other vigorous exercise, for 2 minutes. After running in place, the subject is to hold his or her breath as long as he or she can. How long in seconds was the breath-holding interval? b. Explain the difference, if any, in results between experiment 2 and 7 using your knowledge of physiology a. b. 7. a.
