1

role of 1,25 OH vit D

absorption of calcium and phosphate

2

cause of low 1,25 OH vit D

malabsorption

3

hypocalcemia and hypophosphatemia

1,25 OH vit d deficiency

4

quid of winter foormula

to see if metabolic acidosis has respiratory compensation

5

expected PACO2 in metabolic acidosis with good respiratory compensation

1,5(hco3-)+8 +-2

6

calculation of anion gap acidosis

Nacl-(cl +Bicarb)

7

Normal anion gap

< 12

8

quid CO2 acid ou basique

acide

9

respiratory compensation in alkalosis metabolic

Increase of co2

10

clue for respiratory acidosis

increase of co2

11

compensation of respiratory acidosis

increase bicarb to compensate

12

quid of bicarb acid ou base

basique

13

what happen in metabolic acidosis(2)

decreased HCO3
CO2 decreases to compensate

14

what happen in respiratory alkalosis(2)

co2 decreased
bicarb decreased to compensate

15

what happen in metabolic alkalosis(2)

bicarb increased
increase co2 to compensate

16

pregnant women with bicarb 44 PH 7,49 why

hyperemesis gravidarum causing metabolic alkalosis

17

physiopatho of high bicarb in vomiting(2)

Perte de H+ in vomiting
stimulation of RAA --->retention d'eau de sodium et de HCO3 -

18

causes of metabolic alkalosis(3)

vomiting
excess of mineralocorticoid
diuretic use

19

hypocalcemia in patient receiving large amount of blood

chelation of calcium by citrate in blood product

20

when to suspect hypocalcemia

in any case of massive transfusion

21

why hypomagnesemia can mimic hypocalcemia(2)

because it causes low PTH
decrease peripheral responsiveness to PTH

22

clue for alveolar hypoventilation

high Paco2 in a context of acidosis

23

Normal Pao2

75-105

24

normal PaCO2

33-45 mm de Hg

25

cause of alveolar hypoventilation and respiratory acidosis(4)

pulmonary thoracic disease
neuro muscular disease
drug induced hypoventilation
primary central nervous system dysfunction

26

pulmonary thoracic disease causing alveolar hypoventilation(4)

COPD
obstruction sleep apnea
scoliosis
obesity hypoventilation

27

neuro muscular disease causing alveolar hypoventilation(3)

Myastheni gravis
lambert eaton syndrome
GB syndrome

28

drugs induced alveolar hypoventilation(3)

sedatives
narcotics
anesthetics

29

primary nervous system disease causing hypoventilation(3)

brainstem lesion
infection
stroke

30

how's A-A nin hypoventilation syndrome

normal < 15
