  • Pink puffer or Blue Blotter
respiratory failure
Respiratory Failure
  • Respiratory failure is present if PaO2 is less than 8 kPa - 60 mmHg.
  • It is sub-classified into one of two types of respiratory failure based on the level of PaCO2:
  • Type 1 respiratory failure:
    • PaCO2 is less than 6.5 kPa
    • PaO2 less than 8 kPa
  • Type 2 respiratory failure:
    • PaCO2 is greater than 6.5 kPa
    • PaO2 is less than 8 kPa
o 2 and oxygen therapy
O2 and oxygen therapy
  • Patients with chronic hypoxia from chronic lung disease
  • Poor PaO2 and good sats
  • Acute unwell hypoxic patients need 100% oxygen
