Overview
Respiratory acidosis is an acid-base balance disturbance because of alveolar hypoventilation. Production of carbon dioxide takes place rapidly and failure of air flow directly increases the partial pressure of arterial carbon dioxide (PaCO2). The regular reference range for PaCO2 is 35-45 mm Hg.
Epidemiology and Demographics
Prevalence
- The prevalence of respiratory acidosis in patients with acute COPD is approximately 75 (95% CI 61 to 90) per100 000/year for men aged 45-79 and 57 (95% CI 46 to 69) per 100 000 for women.[1]
