breathlessness
The aroma-seal use group had mean breathlessness scores of 2.48 ± 1.09, 1.74 ± 0.89, and 1.84 ± 0.86 at baseline, first week, and second week of the intervention, respectively, indicating that the scores changed from “it’s rather breathlessness” to “it’s not very breathlessness” in many patients. Conversely, the placebo-seal use group had mean breathlessness scores of 2.37 ± 0.93, 2.17 ± 0.79, and 2.30 ± 0.92 at baseline, week 1, and week 2, respectively, with no significant change in breath comfort when wearing a mask. Furthermore, the aroma-seal use group showed a significantly lower 0.5-point difference in mean breathlessness score change from baseline than the placebo-seal use group in the one- and two-week time points (
