Narrative review outlines distinct clinical consequences of ventilatory pump failure in respiratory disease, highlighting hypercapnia as the hallmark of muscle dysfunction.

Key Points

To describe the functional components of the respiratory system and differentiate the clinical manifestations of gas-exchange failure from ventilatory pump failure.
Conceptual review detailing the dual components of the respiratory apparatus: the gas-exchanging lungs and the neuromuscular ventilatory pump.
Physiological analysis of arterial blood gas patterns associated with isolated lung disease versus mechanical pump dysfunction.
Intrinsic lung disease impairing gas exchange leads to hypoxemia characterized by normocapnia or hypocapnia.
Dysfunction of the ventilatory pump—including the chest wall, respiratory muscles, or neural control—results in hypoventilation, causing hypoxemia coupled with hypercapnia as the hallmark of ventilatory failure.
