The Impact of Unpredictability on Dyspnea Perception, Anxiety and Interoceptive Error Processing
Conclusion
Taken together, the present study demonstrated that unpredictability of upcoming dyspnea increases the perception of dyspnea, especially its affective unpleasantness. Moreover, this effect seems related to increased state and trait anxiety and interoceptive error processing, especially when the occurrence of dyspnea is particularly unpredictable such as in early experimental phases. Future studies are required to further substantiate these findings in patients suffering from dyspnea.
