从呼吸困难发生机制到呼吸康复策略:呼吸系统疾病的临床实践路径OA

Dyspnea in respiratory diseases can be understood as a mismatch between increased ventilatory demand and insufficient respiratory system output.Major mechanisms include dynamic hyperinflation and reduced ventilatory efficiency,gas exchange abnormalities,respiratory muscle dysfunction,and the influence of higher brain centers and psychological effects.In the context of exercise settings,these mechanisms are often triggered,amplified and overlapped,leading to the occurrence and exacerbation of exercise-induced dyspnea.Assessment of dyspnea should focus on identifying treatable traits rather than merely rating symptom intensity.Analysis of sensory characteristics,triggering factors,and mechanistic patterns helps define therapeutic targets and guide individualized rehabilitation strategies.Mechanism-oriented interventions for respiratory rehabilitation are discussed,including breathing pattern training,respiratory muscle training,cognitive-behavioral strategies,and other non-pharmacological approaches,and principles for deciding on exercise intensity and cycles are proposed.Establishing the the corresponding relationship of"symptom-assessment-mechanism-intervention"helps to achieve more targeted and more effective dyspnea management.Thus,starting from mechanisms of dyspnea,a clinical practice pathway of"symptom description-assessment methods-main mechanisms-rehabilitation intervention"is established.
