A síndrome de hipoventilação da obesidade é caracterizada por obesidade (em adultos, índice da massa corpórea > 30 kg/m²) e hipercapnia diurna indicada por pressão parcial arterial de dióxido de carbono (PaCO2)> 45 mm Hg que não pode ser totalmente atribuída a uma doença cardiopulmonar ou neurológica subjacente. A hipercapnia piora durante o sono e geralmente está associada a grave dessaturação arterial de oxigênio. A apneia obstrutiva do sono também está presente na maioria dos casos e deve ser diagnosticada juntamente com a obesidade-hipoventilação._x000D_ Nota: Um diagnóstico definitivo requer a demonstração de hipercapnia diurna e evidência objetiva baseada em polissonografia, com monitoramento de dióxido de carbono (CO2) (por medidas arteriais, no ar expirado no final da expiração ou transcutaneas). | |||

Obesity hypoventilation syndrome is characterised by obesity (in adults, Body-Mass-Index > 30 kg/m²) and daytime hypercapnia indicated by arterial partial pressure of carbon dioxide (PaCO2) > 45 mm Hg that cannot be fully attributed to an underlying cardiopulmonary or neurologic disease. Hypercapnia worsens during sleep and is often associated with severe arterial oxygen desaturation. Obstructive sleep apnoea is also present in the majority of cases and should be diagnosed in addition to obesity hypoventilation.
