Patients with chronic airflow limitation tend to breathe with rapid shallow respirations, but the precise relationship between airflow limitation and these changes in breathing pattern is not clear. Furthermore, as airflow limitation increases, patients experience increasing dyspnea and deterioration of breathing patterns. This ultimately leads to a decline in activity tolerance. Hence, the majority of nursing interventions are directed toward reducing dyspnea and improving breathing patterns. As was pointed out, there is a limited body of knowledge on which to base clinical decisions and interventions; hence further research is needed in this area.
患有慢性气流受限的患者往往呼吸急促且浅，但是气流受限与这些呼吸模式变化之间的确切关系尚不清楚。此外，随着气流受限加剧，患者会感到越来越严重的呼吸困难，呼吸模式也会恶化。这最终会导致活动耐力下降。因此，大多数护理干预措施旨在减轻呼吸困难并改善呼吸模式。如前所述，用于临床决策和干预的知识有限；因此该领域需要进一步研究。
