Hypercapnia develops in one third of patients with advanced chronic obstructive pulmonary disease (COPD) and is associated with increased morbidity and mortality. It affects people who have chronic obstructive pulmonary disease (COPD). Acute hypercapnia is a life-threatening emergency. Multiple factors in COPD are thought to contribute to the development of hypercapnia including increased carbon dioxide (CO2) production, increased dead space ventilation, and the complex interactions of deranged respiratory system mechanics, inspiratory muscle overload and the ventilatory control center in the brainstem. If you notice any of these symptoms, call your doctor. A sudden rise in carbon dioxide, called acute hypercapnia, is more dangerous, because your kidneys can't handle the spike. Hypercapnia, defined as an elevation in the arterial carbon dioxide tension, is commonly encountered during the evaluation of patients with dyspnea and/or altered sensorium.
