Hypoxia is a pathological condition in which the entire body or a particular region is deprived of adequate oxygen supply

• Types of hypoxia:

  • Cytotoxic (histotoxic) hypoxia: tissues are unable to utilize oxygen, e.g., cyanide or carbon monoxide poisoning

  • Anaemic hypoxia: reduced oxygen-carrying capacity of blood due to low haemoglobin concentration

  • Hypoxic hypoxia: caused by low environmental oxygen (e.g., high-altitude sickness)

  • Stagnant (ischaemic) hypoxia: poor blood circulation (e.g., heart failure, localized blood flow obstruction)

  • Carbon monoxide hypoxia: CO binds irreversibly to haemoglobin, blocking oxygen transportSymptoms commonly include:

  • Breathlessness, rapid heartbeat, rapid breathing, anxiety, lethargy, confusion, and communication difficulties
