In type II respiratory failure,there is
Low pO2 and low pCO2
low pO2 and high pCO2
Normal pO2 and high pCO2
Low pO2 and normal pCO2
Ref Harrison 19 th ed. pg1731-1732 Type II respiratory failure is characterized by decreased paO2 and incresinc paCO2 as a result of alveolar hypoventilation.there is fall in minute ventilation which causes a rise in PaCO2 and fall in PaO2. The alveolar aerial gradient is normal in Type 2 respiratory failure.
