More ventilation than perfusion PAO2 increases Hi. PACOZ is lower 1. This happens because of less perfusion to pick up the air

a Upper lung 1. More ventilation than perfusion PAO2 increases Hi. PACOZ is lower 1. This happens because of less perfusion to pick up the air.. So we hold more oxygen and do not receive more PACOZ b. Lower lung i. Less ventilation than perfusion 1. PAO2 decreased iu PACO2 is higher 1. This happens because less ventilation and more perfusion.. So the blood picks up the Oxygen and drops off more COZ 2. Remember the capillary blood values (PCCO2 and PCO2) mimic that of the alveolar 3. Know what the Respiratory Quotient is: 0.8 or 250 ml (oxygen consumed) to 200 ml of carbon dioxide produced by our cells at the tissue level. 200/250= 0.8 a. (internal respiration) 4. Know that the respiratory exchange ratio mimics the respiratory quotient : How much oxygen the alveoli take in and how much carbon dioxide is exhaled a. External respiration Know disorders that increase and decrease the V/Q ratio. a. What makes ventilation higher than the perfusion or vise versa Control of Ventilation 1. Know that the ventral respiratory group is responsible for triggering inspiration and also coordinates the rate, rhythm, and depth of breathing 2. Know what the Hering-Breuer Reflex is 3. Know how systemic blood pressure causes the aortic and carotid sinus baroreceptors to initiate different reactions. a. Low pressures b. High pressures Renal System 1. Know that the hormone ADH is antidiuretic hormone: a diuretic causes urine to be produced and antidiuretic would stop the production of urine. a. What stimulates or inhibits the production of ADH and why does it do that.. . When the concentration of Sodium is elevated .. What happens to the individual? 3 . Know what can cause renal failure… prerenal, renal, and post renal conditions 4. What are some common cardiopulmonary problems that can develop with renal failure 5. How does mechanical ventilation affect urine production and ADH? 6. Know the abbreviations for the following: Na-Sodium, K-Potassium, Ca-Calcium, Mg-Magnesium
