Case 6. COPD with CO2 Retention

Question 1

Describe the gas exchange and acid base status :

PAO2. 6.4
PACO2. 6.9
H+. 52. PH 7.2
HCO3. 24

Answer 1

Moderate type 2 Respiratory impairment
Uncompensated respiratory acidosis

This man needs NIV urgently. He’s already very hypoxia, acidotic and retaining CO2. Merely reducing his FiO2 will decrease his PAO2 further.
