  • Title: [Fatigue of the respiratory muscles].
    Author: Aubier M.
    Journal: Presse Med; 1984 Sep 29; 13(33):2009-12. PubMed ID: 6238298.
    Abstract:
    When respiratory muscle demands for energy exceed supplies, the energy stored within the muscles is depleted and the force of contraction diminishes. This state is called inspiratory muscle fatigue. When it occurs alveolar ventilation decreases, arterial carbon dioxide tension (Pa CO2), increases and hypercapnic respiratory failure ensues. It has also been suggested that such a dysfunction of the respiratory muscles contributes to the pathogenesis of dyspnoea. The purpose of this article is to review: those factors that predispose to respiratory muscle fatigue and determine energy demand and supply, and the principal means of investigation available, including the study of pressures created by muscular contraction, and electromyography.
