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
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
