title: Effect of cervical spinal cord hemisection and hemidiaphragm paralysis on arterial blood gases, pH, and respiratory rate in the adult rat.
abstract: We documented the changes that occur in arterial blood gases, pH, and respiratory rate in rats subjected to a C2 spinal cord hemisection which results in paralysis of the ipsilateral hemidiaphragm. The results indicated that rats compensate for hemidiaphragm paralysis by maintaining arterial pO2 through an increased rate of respiration. This observation is of interest because it implies a form of functional recovery from spinal cord injury which has heretofore not been demonstrated.
