ABSTRACT: Central neurogenic hyperventilation (CNH) is a rare condition and defined as a syndrome comprising normal or elevated arterial oxygen tension, decreased arterial carbon dioxide tension, respiratory alkalosis with hyperventilation even during sleep, and the absence of a peripheral respiratory stimulus. The diagnosis of CNH requires the exclusion of pulmonary, cardiac, metabolic-immunological disorders and some medicines that can result in hyperventilation. We detailed the case of CNH in the 4th day after vascular surgery probably secondary to acute metabolic acidosis with hyperlactatemia, due to severe hypothyroidism in the context of critically ill patient.
