lhypercapnie
Hypercapnia, also called hypercarbia, is an elevation of carbon dioxide (CO2) in the blood, typically defined by a PaCO2 above 45 mmHg on arterial blood gas. It results from an imbalance between CO2 production and its elimination by the lungs, most often due to inadequate ventilation.
Common causes include chronic hypoventilation from diseases such as chronic obstructive pulmonary disease (COPD) and obesity
Clinical presentation varies with severity and the rapidity of onset. Acute hypercapnia may cause headache, dizziness,
Diagnosis relies on arterial blood gas measurement showing elevated PaCO2 and respiratory acidosis, sometimes with concurrent
Management focuses on treating the underlying cause and supporting ventilation. Options range from noninvasive ventilation (nIV)
