Background: The Functional Assessment of Chronic Illness Therapy (FACIT) for Dyspnea was developed to assess multidimensional dyspnea using two subscales (experience of dyspnea and functional limitation) and a total score. Objects: This study aimed to assess the reliability and validity of the Korean version of the FACIT-dyspnea 10-item short form questionnaire (FACIT-dyspnea-K). Methods: Subjects were 163 patients with cancer. Dyspnea-related scales (modified Medical Research Council scale [mMRC], European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 [EORTC QLQ-C30], Hospital Anxiety and Depression [HAD], and WHO Performance Scale) were used to validate the FACIT-dyspnea-K. Results: Internal consistency was confirmed by Cronbach’s alpha values of 0.90 and 0.95 in factors 1 and 2, respectively. Convergence validity was determined by comparing the two factors and total score of the FACIT-dyspnea-K with conceptually related assessment tools measuring the physical and emotional effects of dyspnea, with which correlations ranged from 0.364 to 0.567. Criterion validity was established by significant differences in the FACITdyspnea- K score between groups when the patients were classified by performance status as assessed by the WHO performance scale. Furthermore, the FACIT-dyspnea-K showed notable correlations with other dyspnea scales (mMRC, EORTC QLQ-C30, and HAD) for cancer patients (r = 0.28 to 0.54). The test-retest reliability of the two factors and total score of the FACITdyspnea- K appeared to be excellent (Cronbach’s alpha = 0.96 to 0.97). Conclusion: This study supports FACIT-dyspnea-K as a valid and reliable instrument to assess the dyspnea experience of cancer patients in clinical settings.

Purpose: This study aimed to evaluate differences in nursing performance of nursing college students following simulator training or video-based training for patients with respiratory distress. Methods: The study used a two-group post-intervention design. The simulator group was trained using a high-fidelity simulator and the video group with a best practices video. Nursing ability was evaluated by video recording participants during a dyspnea simulation exercise. The collected data was analyzed with a t-test using SPSS 21. Results: The simulator group showed lower scores than the video group in the preparation (t = -4.60, p < .001) and nursing intervention (t = -2.41, p = .033) categories. Conclusion: Video training is effective for simulation education in cases of dyspnea.

생체 폐를 대신해서 임시적으로 제공하는 폐 보조 장치(LAD)의 사용은 기계 환기술의 단순화와 체외순환 막형 인공폐의 기능을 결합하여 급성호흡부전 환자에 적합하다. 본 연구에서의 주 관심은 폐 보조 장치에서의 막 진동 효율에 있었으며 정량적인 실험 측정은 혈액 용혈에 대한 막 진동 의존을 확인하기 위하여 실행하였다. 또, 혈액 용혈은 막 진동이 이루어질 때 한계 용혈의 가진 주파수 대에서 결정하였다. 최대 기체 전달율을 보이는 675의 중공사 막으로 이루어져 있는 유형 5의 가진 주파수에서 최대 진폭의 발생 및 중공사에 진동의 전달에 의해 최대 산소 전달율이 일어났다. 이 주파수가 혈류량에 가동 가능했던 제 2 형태의 공진 주파수가 되어 높은 각 혈류량 비에서 25±5 헤르쯔까지 가진이 되었으며, 혈액 용혈은 25±5 헤르쯔의 가진 주파수에서 상대적으로 낮았다. 따라서 우리는 이 폐 보조 장치의 한계 용혈 주파수가 25±5 헤르쯔인 것으로 결정했다.
