Abstract

Respiratory dysfunction is an important component of functional disorders associated with stroke. Damage to the respiratory center or related motor pathways after stroke can directly cause changes in respiratory patterns and a decrease in respiratory muscle strength; secondary pneumonia after stroke, and sleep apnea associated with stroke are other common respiratory functional abnormalities that affect the prognosis of stroke patients. Routine physical examinations in clinical practice are the basis for evaluating respiratory function. Stroke patients should particularly pay attention to changes in respiratory patterns, respiratory muscle volume, and muscle tension. Pulse oximetry monitoring with a finger clip can be used to screen for moderate to severe respiratory dysfunction; arterial blood gas analysis, sleep breathing monitoring, mechanical, imaging, and electrophysiological methods can also be used to quantitatively evaluate respiratory function. The main purpose of respiratory function rehabilitation is to increase respiratory muscle strength and endurance, improve coughing ability, alleviate sleep apnea and hypopnea phenomena, thereby enhancing cardiopulmonary adaptability and improving quality of life.
