Flashcards in Small Group 3 Gas Exchange Deck (4):
1

What is the cause of accentuated P2 in COPD patients

increase pulmonary pressure causes early closing of P2

2

How do diuretic cause metabolic alkalosis?

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

3

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)

4

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
