Flashcards in Esquivel: Acid-Base Conversions Deck (12):
1

Metabolic alkalosis compensation?

+10 bicarb = +6 PCO2

2

Acute Respiratory alkalosis compensation?

-10 PCO2 = +0.08 in pH and -2 HCO3

3

Chronic Respiratory alkalosis compensation?

-10 PCO2 = +0.02pH and -5 HCO3

4

Acute Respiratory acidosis compensation?

+10 PCO2 = -0.08 pH and +1 HCO3

5

Chronic Respiratory acidosis compensation?

+10 PCO2 = -0.03 pH and +3.5 HCO3

6

A-a gradient?

150- (5/4)pCO2 - PaO2

7

pt with PCP - when to give steroids?

Aa gradient>35 or PO2<70

8

C diff: Mild, Moderate vs Severe (Tx for each?)

Mild: Less than 6 BMs, fever under 101, WBC under 12, under 65 (Oral Metronidazole)

Moderate: 6-12 BMs, fever 101-103, WBC 12-25, over 65y

Severe - BM over 12, fever over 103, WBC over 25, sepsis (Metronidazole + vancomycin)

9

Why would a MS pt with metabolic acidosis also has respiratory acidosis?

respiratory muscle not able to accurate compensate for metabolic acidosis (can't breathe faster)

10

Pt with anion gap acidosis: next steps?

1) Winter's Formula

2)Calculate Delta-Delta AG - (nl AG) + bicarb =

28 met alk in addition

11

Causes of Respiratory Alk?

Causes of Resp. Alk with pancreatitis?

Lung (PE, ARDs), Liver (cirrhosis) anxiety/pain, sepsis

PE, ARDS, sepsis

12

Cause of chronic respiratory alkalosis?

cirrhosis
