Abstract:
Blood gas analysis was performed in 65 normal adults, 90 patients with chronic bronchitis and 173 with cor pulmonale. Altogether 401 determinations were done. It was found that the P(A-a)O2 was significantly higher in patients with chronic bronchitis and cor pulmonale than in normal adults. When considered comprehensively with the parameters of pulmonary ventilation and diffusion functions and the ventilation/perfusion ratio, P(A-a)O2 possesses definite clinical significance. In various kinds of acid-base disturbance, P(A-a)O2 is the highest in decompensatory respiratory acidosis, and the lowest in compensatory respiratory acidosis.
