This study examined the effects of subject education and oximetry on discomfort sometimes associated with slow-paced breathing (dyspnea). This study was performed because some people report anxiety about getting sufficient oxygen while breathing slowly. Clinical experience suggested that reassuring subjects unaccustomed to slow-paced breathing that they are receiving enough oxygen may lead to greater comfort. The study had a sample size of 20 sequentially randomized healthy adults constituting two groups of 10 subjects. Both groups underwent 5 min of video-guided paced breathing at a rate of six breaths per minute. One group was able to view oximetry and hear an educational script, and the other received neither the educational script nor the viewable oximetry. Subjects answered a questionnaire about ease and adequacy of respiration as well as comfort. Analysis of the questionnaire showed that the group who received education about oximetry and viewed an oximeter during training felt significantly greater comfort during slow breathing than the conventional paced breathing group (p < 0.01). While further study is warranted, these preliminary findings suggest the potential need for this dyspneic effect to be taken into account in clinical practice as well as in research.

在慢节奏呼吸中影响舒适度的学科教育和血氧饱和度试验研究。

这项研究检查了受试者的教育和血氧饱和度对有时与慢节奏呼吸（呼吸困难）相关的不适的影响。进行这项研究的原因是，有人报告担心缓慢呼吸时会获得足够的氧气。临床经验表明，让不习惯缓慢呼吸的受试者放心，他们正在接受足够的氧气，可能会带来更大的舒适感。该研究的样本量为20位依序随机分布的健康成年人，组成10组受试者的两组。两组均以每分钟六次呼吸的速度进行了5分钟的视频引导的定速呼吸。一组能够查看血氧饱和度并听到教育性文字，而另一组既没有收到教育性文字，也没有收到可见的血氧饱和度。受试者回答了关于呼吸的舒适性和充分性以及舒适度的问卷。对问卷的分析表明，接受过血氧饱和度教育并在培训期间看过血氧仪的组与传统的有节奏的呼吸组相比，在呼吸慢时的舒适度明显更高（p <0.01）。尽管有必要做进一步的研究，但这些初步发现表明，在临床实践和研究中都可能需要考虑这种呼吸困难的作用。
