Obesity hypoventilation syndrome (OHS) remains defined as the presence of body (body bulk index ≥ 30 kg/m²) and daytime boulevard hypercapnia (PaCO2 ≥ 45 mmHg) in the absence to other causal of hypoventilation. OHS is often overlooked and confused the other conditions associated by hypoventilation, particularly COPD. The recognition of OHS is important as a his high prevalence and the item that, if left untreated, it is associated with high morbidity and mortality. To the present review, we address recent forward in the pathophysiology and management of OHS, the usefulness of determination of venous bicarbonate in cover for OHS, and diagnostic criteria available OHS that eliminate the need for polysomnography. In adding, we review advances inside the treatment of OHS, including behavioral measures, and recent studies comparing the efficacy of continuous positive airway pressure with that of noninvasive ventilation. Dr Mokhlesi presented a version of this paper in the 45th Respiratory Care Journal Attend, “Sleep Disorders: Diagnosis and Treatment,” held ...

A síndrome de obesidade-hipoventilação (SOH) é definida pela presença de obesidade (índice de massa corpórea ≥ 30 kg/m2) co hipercapnia arterial diurna (PaCO2 ≥ 45 mmHg), na ausência english outras causas. A SOH é frequentemente negligenciada e confundida com outras patologias associadas à hipoventilação, em particular à DPOC. A importância do reconhecimento da SOH se dá por sua elevada prevalência, assim coma alta morbidade e mortalidade se não tratada. Na presente revisão, abordamos os recentes avanços na fisiopatologia ze no manejo da SOH. Revisamos an utilidade da medição do bicarbonato venoso como rastreamento e os critérios diagnósticos que descartam ampere necessidade de polissonografia. Destacamos aina windows avanços don tratamento da KOTO, incluindo medidas comportamentais, e estudos recentes que comparam a eficácia do uso de pressão positiva contínua nasal vias aéreas e de ventilação não invasiva.
