Introduction Fan therapy has gained attention as a non-pharmacological treatment for alleviating dyspnea in patients receiving palliative care and in those with chronic progressive diseases. However, the effectiveness of fan therapy for dyspnea in critically ill patients in intensive care units (ICUs) remains unclear. This study aimed to investigate the efficacy and safety of fan therapy for lung transplant patients in the ICU. Methods Fan therapy was performed on lung transplant recipients (age >18 years) who experienced dyspnea during their ICU stay. A tabletop portable fan was used to blow air on the patient\'s face for five minutes providing fan therapy. The intensity of dyspnea before and after the fan therapy was determined, and a statistical analysis was conducted using a paired t-test to evaluate the changes. Results Between May 2023 and February 2024, 16 patients who were admitted to the ICU following lung transplantation were screened, and eight patients received fan therapy. Fan therapy was performed at a median of postoperative day 12. Seven patients (87.5%) received mechanical ventilation via tracheostomy. The mean (±standard deviation) numerical rating scale (NRS) for dyspnea before and after fan therapy was 5.6±2.3 and 4.4±1.5, respectively (p = 0.08). The mean (±standard deviation) respiratory distress observation scale (RDOS) before and after fan therapy was 4.8 ± 2.0 and 3.8 ± 1.7, respectively (p = 0.03). No serious adverse events were observed, and no significant alterations were observed in the respiratory rate, oxygen saturation levels, pulse rate, or blood pressure. Conclusion The findings suggest that fan therapy can be safely used to relieve dyspnea in lung transplant recipients during their ICU stay. Further evaluations in larger trials are required to confirm the results of this study.

Fan therapy is a non-pharmacological approach useful in terminally ill patients that relieves dyspnea by directing a fan to blow air on one side of the patient\'s face. To date, there has been no systematic review of fan therapy for critically ill patients in the intensive care unit. This scoping review aimed to provide a comprehensive overview of fan therapy studies published to date, clarify the therapeutic intervention methods of fan therapy, evaluate its safety according to existing literature, and explore its potential use in critically ill patients. A scoping review was conducted using the Joanna Briggs Institute methodology. This scoping review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension of the scoping reviews statement. All published studies conducted on patients who received fan therapy regardless of age, disease, setting, phase, country, or follow-up duration were included. The data sources included Medical Literature Analysis and Retrieval System Online, Embase, Cochrane Central Register of Controlled Trials, and Cumulative Index to Nursing and Allied Literature databases. Of the 685 studies obtained, 15 were included, comprising patients with terminal cancer and chronic lung diseases. The most common intervention was a single five-minute intervention for dyspnea at rest. The studies on patients receiving oxygen therapy did not report adverse events or worsening of blood pressure, pulse rate, respiratory rate, or SpO2 levels. However, there are no studies in the literature on the use of fan therapy for critically ill patients. Nevertheless, previous studies suggest that fan therapy is safe.

BACKGROUND: The application of a handheld fan may reduce patients\' shortness of breath and increase their activity tolerance by enabling cooling and air flow into the second and third branches of the trigeminal nerve.
OBJECTIVE: The aim of the study was to assess the effects of directing a handheld fan toward the face in the management of lung cancer-related dyspnea.
METHODS: Using a randomized controlled experimental design, 96 inpatients with lung cancer were evaluated, with the experimental group (n = 49) using a handheld fan to manage dyspnea for 14 days. Dyspnea, respiration rate, oxygen saturation, heart rate, and quality of life were assessed for both groups.
RESULTS: A statistically significant difference was found in dyspnea scores between groups on the first, seventh, and fourteenth days of fan application, and statistically significant differences were found between groups in dyspnea scores, respiration rates, oxygen saturation, heart rate, and quality of life on the fourteenth day of application.

BACKGROUND: Dyspnea is a common distressing symptom in patients with malignant and nonmalignant diseases. Fan therapy, which uses a fan to blow air toward the patient\'s face, can alleviate dyspnea; however, its efficacy remains unclear.
OBJECTIVE: To examine the immediate efficacy of fan therapy for alleviation of dyspnea at rest.
METHODS: Meta-analysis.
METHODS: We searched the Cochrane Central Register of Controlled Trials in the Cochrane Library, MEDLINE EBSCO, CINAHL EBSCO, and Scopus from January 1, 1987, to August 21, 2018 (PROSPERO-CRD42018108610). In addition, we hand-searched studies and used the similar articles feature on PubMed to search for articles. Randomized controlled trials comparing the effects of fan therapy with placebo or other interventions to alleviate dyspnea at rest, in which patients were aged ≥18 years, were eligible for inclusion in the review. We excluded articles on long-term intervention involving fan therapy and complex intervention (including fan therapy). The risk of bias assessment was conducted using the Cochrane tool, and the meta-analysis was performed using RevMan version 5.3.
RESULTS: We identified a total of 218 studies; 2 met our criteria for inclusion in the meta-analysis. Fan therapy significantly improved dyspnea at rest in terminally ill patients with cancer compared to control groups (mean difference: -1.31, 95% confidence interval: -1.79 to -0.83, P < .001). There were no studies that met the inclusion criteria regarding fan therapy for patients with nonmalignant disease.
CONCLUSIONS: This meta-analysis demonstrated that fan therapy may be an effective intervention for dyspnea at rest in patients with terminal cancer.

Background: Dyspnea is one of the most common symptoms in patients with advanced disease and terminal illness, associated with poorer quality of life. The efficacy of fan therapy to palliate dyspnea is inconsistent and unclear. Objective: The aim of this meta-analysis was to evaluate the efficacy of fan therapy for the relief of dyspnea in adults with advanced disease and terminal illness. Design: The CENTRAL, MEDLINE, EMBASE, CINAHL, and PsycINFO were searched to retrieve all randomized controlled trials examining the benefits of fan therapy for the relief of dyspnea in patients at the advanced stages of illness. Risk of bias was assessed according to the Cochrane Collaboration standard scheme. Results: Five studies involving 198 adults were identified. Fan therapy was associated with a significant relief of breathlessness intensity immediately after intervention (mean differences [MDs], -1.01; 95% confidence interval [CI], -1.57 to -0.45; p < 0.001) and 10 minutes after intervention (MDs, -0.90; 95% CI, -1.53 to -0.27; p = 0.005). Long-term application of fan therapy for at least one month was not related to changes of dyspnea severity (MDs, 0.10; 95% CI, -1.14 to 1.35; p = 0.870). However, significant heterogeneity and low quality of the included trials limit applicability of the results in general practice. No difference was found in activity performance, respiratory rate and SpO2, changes in other symptom intensities, and adverse events. Conclusion: Current trials provided low-quality evidence for a significant short-term effect after fan therapy in the relief of dyspnea and no beneficial effect in the long-term application in adults with advanced disease and terminal illness.

OBJECTIVE: To clarify the duration required for dyspnea to return to baseline severity after fan therapy, to evaluate whether fan-to-legs therapy or no fan therapy would be a suitable control therapy, and to investigate changes in patients\' face surface temperature after fan therapy.
METHODS: In this pilot study, all participants received 3 interventions in the following order: no fan, fan to legs, and fan to face. Participants used a fan for 5 minutes, and they scored their dyspnea at 10-minute intervals for 60 minutes or until the score had returned to its baseline value, whichever occurred first. Nine patients with advanced cancer admitted to a palliative care unit were included; they had dyspnea at rest and rated its severity as at least 3 points on a 0- to 10-point numerical rating scale. Descriptive statistics and the Wilcoxon signed rank test were used to analyze the data.
RESULTS: All patients completed the study. Of the 9 participants, 6 experienced a clinical benefit from using a fan to their faces. Of these patients, only 2 participants\' (2 of 6) dyspnea scores returned to baseline by the end of the 60-minute assessment period after exposure to fan-to-face therapy. In fan-to-legs and no fan settings, there was no change in the dyspnea scores. There were significant differences between the baseline face surface temperature and that after fan-to-face and fan-to-legs settings.
CONCLUSIONS: When using a crossover design to investigate the effect of fan therapy on dyspnea, 1 hour is an insufficient washout period.

BACKGROUND: Fan therapy is often suggested for relieving the symptom of dyspnea in patients with advanced cancer, but relevant literature among Asians is limited.
OBJECTIVE: Phase 2 clinical trial to assess the clinical feasibility and outcome of using an electric fan to alleviate the symptom of dyspnea in Chinese patients with advanced cancer.
METHODS: Thirty patients with advanced cancer having unresolved breathlessness were recruited from Hospice and Palliative Care Centre of Kiang Wu Hospital in Macau. Participants were randomly and equally allocated to the experimental group and the control group, respectively.
METHODS: Verbal numerical rating scale (NRS) of breathlessness, respiratory rate (RR), and saturation of peripheral oxygen (SpO2) was collected before and after the intervention.
RESULTS: T test was used to analyze the data collected. There was a significant difference in the NRS scores of the experimental group ( P < .01), indicating a significant reduction in the patients\' sensation of breathlessness after fan therapy, whereas no significant difference was found in the objective statistic results of RR and SpO2. No significant difference ( P > .05) was found in the control group for all the 3 variables before and after routine treatment.
CONCLUSIONS: The results of the study suggested that fan therapy could be effective in alleviating dyspnea in Chinese patients with advanced cancer. It should be considered as one of the nonpharmacological treatment option. Future large-scale phase 3 clinical trials are warranted.
