Synopsis of Experiment

  1. A spirometer will be used to measure respiratory volumes and breathing rate in three female Caucasian subjects that are 25 years of age and 65 inches tall.
  2. Breathing rate and the following volumes, TV, IRV, and ERV, will be measured in the subjects at rest and after 2 minutes of exercise.
  3. RV will be estimated using an equation, and minute ventilation will be calculated from breathing rate and TV.
  4. VC, IC, FRC, and TLC, will be calculated from TV, IRV, ERV, and calculated RV.
  5. Compare resting and post-exercise TV, IRV, ERV, VC, IC, FRC, TLC, breathing rate, and minute ventilation.
