Type 1 respiratory failure
A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise type 1 respiratory failure — the full SA Note notes add investigations, management, complications and 10 practice questions.
Key high-yield points
- Type 1 respiratory failure: PaO2 <8 kPa with normal or low PaCO2 (≤6.0 kPa) - problem of oxygenation, not ventilation
- PaCO2 stays normal/low because CO2 is more diffusible - hyperventilation compensates until late deterioration
