Hypoxia
Excerpt
Hypoxia occurs when oxygen is insufficient at the tissue level to maintain adequate homeostasis, stemming from various causes such as hypoventilation, ventilation-perfusion (V/Q) mismatch, or right-to-left shunting. This condition can arise from inadequate oxygen delivery to the tissues due to either low blood supply or low oxygen content in the blood, also known as hypoxemia.
Hypoxia can manifest across a spectrum of intensity, ranging from mild to severe, and present in acute, chronic, or mixed acute and chronic forms. The response to hypoxia varies among tissues—while some tissues can tolerate certain forms of hypoxia or ischemia for extended periods, others are significantly impaired by low oxygen levels.
