hi all,i have a question about ohdc. the curve is shifted to the left when there's an increase in o2 and ph and a decrease in temp and co2. but will there be a shift to the left during times of stress or when hco3- levels increase?i have in my notes that a shift to the left occurs during alkalosis. well, uncompensated metabolic alkalosis is an increase in ph and increase in hco3-. where as uncompensated respiratory alkalosis is an increase in ph and a decrease in co2.respiratory alkalosis can occur from pain, fear, anxiety, stress, fever, etc. metabolic alkalosis occurs from vomiting, ng suctioning, hypokalemia, diuretic use. respiratory can be caused by stress and metabolic has the increased hco3-.are both answers correct to my question? thanks in advance!!!
