The purpose of this study was to test the efficacy of lavender aromatherapy via inhalation as a stress management modality for patients in cardiac rehabilitation. This was a quasi-experimental design. Aromatherapy was provided via inhalation to participants before a cardiac rehabilitation session over 8 minutes using lavender essential oil. The same protocol was used in the non-aromatherapy session without the essential oil. Blood pressure and radial pulse were measured, and subjective data were also collected including assessment of stress level (1-10 scale) and affect using the Positive and Negative Affect Schedule (PANAS). Analyses were performed using SPSS Statistics version 20. Quantitative measures were analyzed using Mann-Whitney nonparametric equivalent to the t test. Inferential measures were analyzed using the χ 2 or Fisher's exact test. In the outpatient cardiac rehabilitation program, 25 patients participated in this study. The average change in negative affect (PANAS-) between pre and post-aromatherapy compared with pre- and post-non-aromatherapy sessions was statistically significant. Results showed a reduction in blood pressure following both aromatherapy and non-aromatherapy sessions with no statistical significance between sessions. Heart rate decreased equally post-aromatherapy and non-aromatherapy sessions. Aromatherapy may be a useful stress management tool for cardiac rehabilitation patients.
本研究旨在测试通过吸入薰衣草香薰作为心脏康复患者压力管理方法的疗效。这是一项准实验设计。在心脏康复治疗前，参与者通过吸入薰衣草精油接受 8 分钟的香薰治疗。在非香薰治疗中，使用相同的方案，但不使用精油。测量血压和桡动脉脉搏，并收集主观数据，包括使用正性和负性情绪量表（PANAS）评估压力水平（1-10 级）和情绪。使用 SPSS Statistics 版本 20 进行分析。定量测量使用 Mann-Whitney 非参数等效于 t 检验进行分析。推断性测量使用 χ 2 或 Fisher's 确切检验进行分析。在门诊心脏康复计划中，25 名患者参与了这项研究。与非香薰治疗前后相比，香薰治疗前后的负性情绪（PANAS-）平均变化具有统计学意义。结果表明，香薰和非香薰治疗后血压均降低，但治疗之间无统计学意义。香薰和非香薰治疗后心率均相等下降。香薰可能是心脏康复患者的一种有用的压力管理工具。
