Title: PhysioEx 8. Exercise 7 Activity 5--- Plz Help
Post by: Caitlyn on Nov 22, 2011
Exercise 7, Activity 5
Exploring Various Breathing patterns

1.)What happens to Pco2 during rapid breathing? Explain your answer
2.) What happens to Pco2 during the entire time of the rebreathing activity?
3.) Did the depth of the breathing pattern change during re-breathing? (Carefully examine the tracing for rate and depth changes; the changes can be subtle.) Explain your observations
4.) What happened to the Pco2 during breath holding?
5.) What happened to the breathing pattern when normal respiration resume?

Please help! Thanks guys

I figured out a few answers. All I need help on is Question 3. Please help and please add anything else if you can.
Thanks

1.) It decreased during rapid breathing. More CO2 was removed from the blood than normal.
2.) PCO2 increased during rebreathing.
3.) Did the depth of the breathing pattern change during re-breathing?? (Carefully examine the tracing for rate & depth changes; the changes can be subtle) Explain your observations?? Help!!!
4.) Increased dramatically during breath holding
5.) It stabilized
