Pulmonary - Acidosis/Alkalosis

1. The best representation of the normal range of pH that we have been taught is:

7.35 - 7.45

7.25 - 7.35

7.3 - 7.4

7.45 - 7.55

2. Match the numbers with the description.

alkalotic

acidotic

Submit

3. Normal range for PaCO2:

2 - 3

45 - 55

35 - 45

Over 100

4. pH………... 7.22 PaCO2…… 55 HCO3-……. 25 What is it?

Metabolic acidosis

Metabolic alkalosis

Respiratory acidosis

1. assess pH: acidotic or alkalotic? acidotic
2. assess PaCO2: acidotic or alkalotic? acidotic - being driven by lungs - respiratory
3. assess HCO3-: acidotic or alkolitic? in normal range - uncompensated respiratory acidosis

Explanation

1. assess pH: acidotic or alkalotic? acidotic
2. assess PaCO2: acidotic or alkalotic? acidotic - being driven by lungs - respiratory
3. assess HCO3-: acidotic or alkolitic? in normal range - uncompensated respiratory acidosis

5. Match the following conditions with their descriptions.

pH less than 7.35 with PaCO2 greater than 45

pH greater than 7.45 with PaCO2 less than 35

Bicarb level greater than 26 with pH greater than 7.45

Submit

6. pH: 7.50 PaCO2: 42 HCO3-: 33 What is it?

Metabolic alkalosis

Respiratory alkalosis

Respiratory acidosis

1. assess pH: acidotic or alkalotic? above 7.45 so alkalotic
2. assess PaCO2: acidotic or alkalotic? within normal range, so not a respiratory source of the problem
3. assess HCO3-: acidotic or alkalotic? above norma range, so alkalotic, so problem is being driven by kidneys.

Explanation

1. assess pH: acidotic or alkalotic? above 7.45 so alkalotic
2. assess PaCO2: acidotic or alkalotic? within normal range, so not a respiratory source of the problem
3. assess HCO3-: acidotic or alkalotic? above norma range, so alkalotic, so problem is being driven by kidneys.

7. pH: 7.32 PaCO2: 32 HCO3-: 18 What is it?

Metabolic acidosis

Respiratory acidosis

Respiratory alkalosis

1. assess pH: acidotic or alkalotic? acidotic
2. assess PaCO2: acidotic or alkalotic? below normal, so alkalotic…it's not driving the acidosis
3. assess HCO3-: acidotic or alkalotic? below normal, so acidotic…this is driving the acidosis
The PaCO2 is way low - lungs are trying to compensate for the kidneys….it's almost working, pH is close to normal. PARTIALLY COMPENSATED METABOLIC ACIDOSIS
