Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without causing respiratory muscle fatigue.
Causes of Hypercapnic Respiratory Failure:
Several factors can disrupt the balance between ventilatory demand and supply, mainly by reducing the ventilatory supply. These factors are categorized into four main groups:
Monitoring and Management:
Close monitoring of respiratory symptoms is essential for individuals at risk of hypercapnic respiratory failure. An increased breathing difficulty or a noticeable change in carbon dioxide levels requires immediate medical attention. Prompt management measures are crucial to prevent severe complications and ensure adequate oxygenation and CO2 elimination.
Management strategies typically aim to treat the underlying cause, enhance ventilation, and provide mechanical ventilatory support when necessary. A comprehensive, multidisciplinary approach involving respiratory therapists, neurologists, and pulmonologists is vital to meet the complex needs of patients with this challenging respiratory condition.
