An Analysis between Pre- and Post-exercise of the Respiratory and Metabolic State for the Acute and Subacute Stroke Patients

  • 1Department of Rehabilitation Medicine, Kwangju Christian Hospital, Gwangju, Korea.


To evaluate oxygenation and metabolic state of the non-brainstem stroke patients after the moderate intensity exercise using arterial blood gas analysis (ABGA). Fifty-two stroke patients were recruited. All the subjects were to follow the instructions for the exercise, not suffered cardiopulmonary diseases before, and not diagnosed with brainstem disorders. They were ordered to maintain 70% heart rate of maximal heart rate during exercise and checked blood pressure, pulse rate, respiratory rate (RR), and ABGA before and after the exercise, respectively. O² saturation, PaO², PaCO², O² content, HCO³â», pH, and anion gap were compared between the exercise, and those data changes were performed correlation analysis into age and the time after stroke onset. The data comparison was also done into the subgroup of the severity of stroke using National Institutes of Health Stroke Scale (NIHSS). The statistically significant results were observed in the change of O² saturation, PaO², PaCO², O² content, HCO3⁻, pH, and anion gap after the exercise. The decrease of HCO³â» and increase of RR were proportional to age, however the data showed no correlation with the NIHSS. These results suggest relatively preserved respiratory compensation mechanism and homeostatic effect to maintain metabolic balance among the non-brainstem stroke patients.
