What is diffusion? - ANSWER Movement of molecules from high to low concentration
Where does gas exchange occur? - ANSWER alveolar-capillary membrane
4 Causes of poor diffusion at the alveolar-capillary membrane - ANSWER 1. Damage
(Atelectasis)
2. Covered with fluid(Pneumonia/ARDS)
3. Insufficient inflation(hypoventilation/poor inspiratory maneuvers)
4. overstretched(High Pplat)
Why do we need to ventilate properly? - ANSWER To regulate and maintain
appropriate amounts of CO2
Co2 regulation second by second - ANSWER Carbonic acid buffer system
What mechanisms produce CO2? - ANSWER Aerobic and anaerobic metabolism
What mechanisms regulate CO2? - ANSWER 1. Being in an aerobic state
2. Blood flow to lungs
3. Proper diffusion
