Detailed explanation-1: -The mechanisms involved in acute hypercapnic respiratory failure include decreased central drive to breathe, weakness of respiratory muscles, abnormalities of the chest wall, and abnormalities of the lung and airways.
Detailed explanation-2: -Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. The fluid keeps your lungs from filling with enough air, which means less oxygen reaches your bloodstream. This deprives your organs of the oxygen they need to function.
Detailed explanation-3: -Acute hypercapnic respiratory failure is usually caused by defects in the central nervous system, impairment of neuromuscular transmission, mechanical defect of the ribcage and fatigue of the respiratory muscles. The pathophysiological mechanisms responsible for chronic carbon dioxide retention are not yet clear.
