Document Summary
Lecture 7: hyperventilation and hypoventilation: calculate alveolar p o2 using the alveolar gas equation and show it changes with. Internal respiration: comsumes oxygen and generates carbon dioxide. Follow concentration gradient = partial pressure of the specific gases. Alveolar p o2 = inspired p o2 consumed p o2. Alveolar p o2 = inspired p o2 alveolar p co2 /rq. With hypoventilation : provide a definition for the respiratory quotient. Rq: ratio describing the relationship between oxygen and carbon dioxide. Dependent on amounts of fat and carbs that we use during rest. 200 ml co 2 and 250 ml o 2 , essentially every minute: explain why oxygen exchange is said to be normally perfusion limited and provide examples when it is diffusion limited instead. Po 2 level in the blood is reached in a quarter of a second and therfore the amount of literal oxygen is gonna be limited.
