Vital capacity

  1. 1. What is tidal volume?
  2. 2. What is Inspiratory Reserve Volume?
  3. 3. What is the Expiratory Reserve Volume?
  4. 4. What is the Vital Capacity?
  5. 5. What is the Residual Volume?
  6. 6. What factors affect vital capacity?
  7. 7. High Altitude Adaptation <ul><li>High Altitude </li></ul>
  8. 8. Measuring Vital Capacity
  9. 9. Part A: Measuring Vital Capacity <ul><li>-Each group will have a respiration bag, one mouthpiece and the lab worksheet </li></ul><ul><li>-Rubbing alcohol will be provided to sterilize the mouthpiece once you are finished. </li></ul><ul><li>-Breathe into the bag, record the number of litres. </li></ul><ul><li>-Repeat last step one more time and calculate your average tidal volume. </li></ul><ul><li>-Once you have calculated the average please record your results on the following page. </li></ul><ul><li>For the purpose of this experiment: </li></ul><ul><li>-ATHLETE: active for at least 10 hours of week. </li></ul><ul><li>-Smoker: Even if you smoke one cigarette a week </li></ul>
  10. 10. Part B: Manipulating Respiratory Rate <ul><li>Choose one person to perform these experiments. </li></ul><ul><li>Read the procedure section of the lab. </li></ul><ul><li>The first sign of faintness or dizziness, stop the experiment and return to normal breathing rate. </li></ul><ul><li>Once you have completed both parts of the lab, clean up your station and place all materials in the proper area. </li></ul>

Class Avearge: 3.45 4.1, 4.0, 1.7 Class Average:3.31 Non-athlete Class Average: Class Average: Athlete Smoker 4.65, 5.3, 3.3, 5.1, 2.6, 3.8 Class Average:4.12 2.8, 3.0, 3.05, 3.75, 2.2, 3.5, 4.6, 3.15, 3.2, 3.1,2.1,2.7, 3.25 Class Average:3.34 Non-athlete 4.2, 5.9 ,4.75, 4.1 Class Average:4.74 3.1, Class Average:3.1 Athlete Non-Smoker Male Female Average Vital Capacity (L) Factors
  13. 13. Materials <ul><li>Mouthpiece (sterilize with rubbing alcohol) </li></ul><ul><li>Respiration Bag (do not use it as a sword) </li></ul><ul><li>Rubbing Alcohol (WHMIS - poisonous, do not drink) </li></ul><ul><li>Lab worksheet </li></ul><ul><li>Paper bag (recycle – do not pop </li></ul><ul><li>the bag) </li></ul><ul><li>Chair </li></ul><ul><li>Paper towels (throw in garbage bin) </li></ul><ul><li>Tissue </li></ul><ul><li>Stop watch </li></ul>
  14. 14. Lab Safety <ul><li>no eating or drinking during the lab </li></ul><ul><li>no running around </li></ul><ul><li>if you feel faint at any moment of the lab please stop and let the teacher know immediately. </li></ul><ul><li>If you have underlying health conditions, especially relating to respiratory problems (i.e.asthma), do not perform the second activity. Please get your partner to be the subject of experiment. </li></ul>
