Obesity Hypoventilation Syndrome-Related Challenges in Acute Respiratory Failure

Abstract

Obesity hypoventilation syndrome (OHS) is a condition commonly found in severely obese patients in which they fail to breathe deeply or rapidly enough to offset the body's need for oxygen consumption and carbon dioxide release. This report presents a case of a 49-year-old super-super-morbid obese female with a body mass index (BMI) of 90 kilogram per meter squared (kg/m²), chronic obstructive pulmonary disease (COPD), and end-stage cor pulmonale, who was brought to the emergency department for altered mental status and requiring emergent airway due to respiratory failure secondary to OHS. The continued increase in rates of obesity worldwide, especially in those with BMI ≥ 50 kg/m², may lead to an increase in the incidence of OHS. With comorbidities secondary to obesity and associated complexity, this medically challenging case emphasizes the need for refined management strategies in caring for OHS in super-super-morbidly obese patients.
