Definition
Decrease in oxygen resulting in the failure to nourish the tissues at the capillary level. (Tissue perfusion problems can exist without decreased cardiac output; however, there may be a relationship between cardiac output and tissue perfusion)
Related Factors
- Interruption of Flow – arterial, venous
- Exchange Problems
- Hypervolemia, hypovolemia
- Mechanical reduction of venous and/or arterial blood flow
- Decreased Hb concentration in blood
- Altered affinity of hemoglobin for O2; enzyme poisoning
- Impaired transport of the O2 across alveolar and/or capillary membrane
- Mismatch of ventilation with the blood flow
- Hypoventilation
