Flashcards in Small Group 3 Gas Exchange Deck (4):

What is the cause of accentuated P2 in COPD patients

increase pulmonary pressure causes early closing of P2


How do diuretic cause metabolic alkalosis?

wasting of chloride anions cause the kidney to retain HCO3- to retain electrical neutrality


How do you calculate anion gap?

Na+- Cl- - HCO3- (can be calculated by rule of 10- change in HCO3- by 10 for each 0.01 change in pH)


When anion gap is not appropriately matched by a reduction in HCO3-, what can we conclude?

suggests the presence of a primary abnormality increasing the concentration of HCO3-, a primary alkalosis
