Inspiratory Occluded Airway Pressure

Part of the Update in Intensive Care and Emergency Medicine book series (UICM, volume 13)


Respiration, as a physiological phenomenon, consists of a series of interconnected organs related in a bi-directional form. Centering our attention on the regulation of ventilation, the primary role of the bulbar respiratory center is noteworthy. This center is constituted by a neuronal clump situated in the medulla oblongata, the axons of which stimulate motor neurons of the anterior spinal horn through long descending pathways. The motor neurons control the contraction of the respiratory muscles producing the entrance of air into the lungs. In this elemental scheme, impulses originating from the cerebral cortex, protuberance and chemoreceptors act as regulatory elements in response to changes in arterial temperature, pH, PO2 and PCO2 [1, 2].
