Abnormalities in Arterial PO2

Question 1

Hypoxia

Answer 1

> Condition of having insufficient O2 at the 
   cell level
Categories 
   - Hypoxic hypoxia
   - Anemic hypoxia
   - Circulatory hypoxia
   - Histotoxic hypoxia

Question 2

Hyperoxia

Answer 2

- condition of having an above-normal 
  arterial PO2
- Can only occur when breathing 
  supplemental O2
- Can be dangerous

Question 3

Hypercapnia

Answer 3

• Condition of having excess CO2 in arterial
  blood
• Caused by hypoventilation

Question 4

Hypocapnia

Answer 4

> Below-normal arterial PCO2 levels
> Brought about by hyperventilation which 
  can be triggered by
-Anxiety states
-Fever
-Aspirin poisoning

Question 5

Hypercapnia

Answer 5

• excess CO2 in arterial blood
• Increase in H+ –> acidosis
• Respiratory acidosis

Question 6

Hypocapnia

Answer 6

Below-normal arterial PCO2 levels
Decrease in H+ –> alkalosis
Respiratory alkalosis
