Q

Examples of PaO2/FiO2

A

(a) PaO2 of 100, divide by FiO2 of 0.5 = 200*
(b) PaO2 of 85, divide by FiO2 of 1.0 = 85*
*low values

17
Q

CO2 is always

A

Acidic

18
Q

HCO3 is always

A

base (alkalotic)

19
Q

Only the ____ can manipulate the CO2

A

lungs

20
Q

Only the _____ can manipulate the HCO3

A

kidneys

21
Q

Acid Base Mnemonic (ROME)

A

a) R Respiratory
(1) O Opposite
(a) pH (high) PCO2 (low) Alkalosis
(b) pH (low) PCO2 (high) Acidosis

b) M Metabolic
(1) E Equal
(a) pH (high) HCO3 (high) Alkalosis
(b) pH (low) HCO3 (low) Acidosis

22
Q

Compensation
1. Mechanisms that normalize the pH when there is acid-base imbalance

A

a) Kidneys compensate for respiratory abnormality (CO2)
b) Lungs compensate for metabolic abnormality (excrete H+ or
retain HCO3)

23
Q

Abnormal pH + one abnormal value (PCO2 or HCO3)

A

Uncompensated

24
Q

(Abnormal pH + 2 abnormal values (pCO2 and HCO3)

A

Partial Compensation

25
Q

Normal pH + abnormal values (pCO2 and/or HCO3)

A

Full Compensation

26
Q

(a) pH: 7.51 High
(b) pCO2: 30 Low
(c) HCO3: 26 Normal

A

Respiratory Alkalosis uncompensated

27
Q

(b) pCO2: 32 Low
(c) HCO3: 18. Low

A

Respiratory Acidosis partial compensated

28
Q

(a) pH: 7.38. Normal
(b) pCO2: 49. High
(c) HCO3: 35. High

A
