Ventilatory control stuff i dont know

Question 1

Ve is matched with Co2 production during what

Answer 1

incremental exercise until anaerobic exercise threshold

Question 2

Does LT cause VT or is it coincidental?

Answer 2

• linked through a stimulation of Ve by chemoreceptors due to an increase in h and CO2
• the h cause the build up of lactate (LT)

Question 3

why does SV plateau

Answer 3

• decrease in preload
  -increase in afterload

Question 4

why would stroke volume continue to increase

Answer 4

• larger venous return producing an increase in EDV and contractility
