RESUMO
Oxygen therapy is widespread in acute care settings as adequate oxygen supplementation is essential in case of hypoxemia. Excessive oxygen supplementation has several unrecognized deleterious effects. This article reviews the deleterious effects of hyperoxemia and sums up the actual recommendations for safe oxygen supplementation.
L'administration libérale d'oxygène dans les soins aigus est fréquente, mais n'est pas anodine. En cas d'hypoxémie, elle est bien sûr indispensable, mais son utilisation abusive peut résulter en une hyperoxie, avec de nombreux effets secondaires. Cet article résume les principes de l'oxygénothérapie ainsi que les effets néfastes provoqués par l'hyperoxie qui sont souvent méconnus.

Coexisting central and obstructive sleep apnea is a challenging clinical situation. We report a case exhibiting an overnight shift from obstructive to central events. The central sleep apnea component was related to sleep instability, hyperventilation and low nocturnal PaCO2. Both types of respiratory events were successfully treated with adaptive servoventilation.
