Here is a quick mnemonic “OXYGEN SATURATION“ to remember about causes Of Hypoxia

This can be valuable for patients as well as medical doctors, nurses & students doing their clinical rounds. You can also find it very useful for med exams like USMLE, NExT Medical Step 1&2, MBBS, NEET PG, INI-CET, FMGE,MCAT & NCLEX exams

Causes Of Hypoxia : How To Remember Easily ?

  • Oxygen transport impaired in Anemic Hypoxia
  • Xeno-toxins like Cyanide cause Xtra mitochondrial cellular hypoxia
  • Your lungs’ respiratory function affects Your Oxygen saturation
  • Greater Oxygen release in Respiratory Hypoxia with right-shifted Hb-O2 curve
  • Elevated metabolic rate leads to increased Exercise-related O2 demands
  • Nonventilated lung regions lead to Non-respiratory shunting hypoxia
  • Specific organ hypoxia due to Shunting or arterial/venous Structural issues
  • At higher altitudes, Alveolar PO2 decreases, causing high-altitude illness
  • Tissue perfusion and O2 extraction contribute to Tissue hypoxia
  • Unacclimated individuals may face challenges at high Unacclimatized altitudes
  • Reduction in Hb concentration leads to Reduced O2-carrying capacity
  • Arterial-mixed venous O2 difference is increased in Circulatory hypoxia
  • Tetralogy of Fallot, transposition of the great arteries, etc., cause Tetralogy hypoxia
  • Inspiring 100% O2 corrects Intrapulmonary shunting hypoxia
  • Oxygen released at lower tensions in Carbon monoxide (CO) intoxication
  • Normal Pao2, but decreased venous and tissue PO2 in Normal and Non-respiratory circulatory hypoxia
