[Changes in acid-base equilibrium of the arterial blood in hypoxemic-eucapnic subjects subjected to oxygen therapy with and without an antiphosphodiesterase drug].

The behaviour of the partial tensions of respiratory gases and the main parameters of acid base balance in hypoxaemic and eucapnic chronic bronchopneumopathics undergoing oxygen therapy has been assessed. The patiests were subdivided into two groups, the first consisting of subjects undergoing oxygen therapy alone, the second of subjects having oxygen and i.v.
