BASTIDAS, Alirio R.; GIRALDO, Luis Fernando; BENAVIDES, Mateo  and  GARCIA, Rafael. Cheyne-Stokes respiration and severe bruxism documented by polysomnography that improves with administration of oxygen at 1 L/min. Acta Med Colomb [online]. 2014, vol.39, n.4, pp.388-392. ISSN 0120-2448.

The case of a 59 year old female diagnosed with anoxic-ischemic encephalopathy, who is in a persistent vegetative state and secondary epilepsy difficult to control, who in the course of her clinical evolution develops central sleep apnea with apnea hypopnea index (AHI) of 87.86 / h with Cheyne-Stokes pattern and severe bruxism documented by polysomnography, alterations that improved after administration of oxygen by nasal cannula at 1 L / min., is presented. The association of bruxism with Cheyne-Stokes respiration and the simultaneous and complete response of the two alterations to the administration of supplemental oxygen has not been reported previously.

Keywords : Cheyne-Stokes respiration; polysomnography; heart failure; bruxism; hypoxemia; apnea.
