II. Definition
- Hypoxia or Hypoxemia
- PaO2 <70 to 80 mmHg
III. Causes
- Respiratory Failure
- Cardiogenic Shock
- Miscellaneous Causes
- Anemia
- Decreased FIO2 of inspired air (high altitude)
- Cyanide Poisoning
- Salicylate Toxicity
IV. Causes: Hypoxia or Hypoxemia (PaO2 <70 to 80 mmHg)
- See Hypoxemia
V. Symptoms
VI. Signs
- Cyanosis
- Tachycardia
- Tachypnea
- Mental status changes
- Acute: Altered Level of Consciousness
- Chronic: Fatigue, drowsy, inattentive
-
Oxygen Saturation (O2 Sat) decreased
- Usually correlates with PaO2
- However, relationship is not linear (See O2 Sat)
- Not sensitive for increased A-a Gradient
- Conditions where O2 Sat low despite normal PaO2
- Carbon Monoxide Poisoning
- Methemoglobinemia or other abnormal Hemoglobin
- Usually correlates with PaO2
VII. Evaluation and Management
- See Dyspnea
- See Respiratory Failure
