Respiratory system mnemonic

Factors shifting the oxygen dissociation curve right

The mnemonic

CADET, face Right

What each word stands for

  • CCO₂ rise
  • AAcid (low pH)
  • D2,3-DPG rise
  • EExercise
  • TTemperature rise

Why it matters clinically

A right shift releases oxygen to tissues, such as in exercise and anaemia.

Where it stops being reliable

It does not cover left-shift factors such as HbF, CO and alkalosis.
