Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease that can be prevented and treated, characterized by persistent and progressive airflow limitation. This condition causes patients to experience shortness of breath and decreased oxygen saturation, therefore requiring non-pharmacological interventions, one of which is the application of the Tripod Position to help improve patient oxygenation. This study used a case study design involving the application of Tripod Position therapy in three respondents diagnosed with COPD. The intervention was carried out for three consecutive days, with oxygen saturation levels being monitored before and after each intervention. The results of the Tripod Position application indicated an improvement in oxygen saturation in all respondents. Respondent 1 experienced an increase in oxygen saturation by 3%, respondent 2 by 1%, and respondent 3 by 3%. Overall, the application of the Tripod Position showed a positive effect in gradually increasing oxygen saturation among COPD patients. These findings suggest that the Tripod Position can be used as an effective non-pharmacological intervention in nursing care for COPD patients. Therefore, the Tripod Position is recommended to be applied as a simple, practical, and supportive therapy to improve oxygen saturation and respiratory function in COPD patients.  

This research aims to analyze the influence of thermal conditions; specifically the temperature difference between the test object and the environment; on the characteristics of air flow and heat transfer around it. The object of this study is a test piece subjected to free air flow under various temperature conditions; focusing on the convection heat transfer phenomenon. The main problem addressed is how temperature variations affect the convection heat transfer coefficient; heat transfer rate; and heat flux; as well as changes in air velocity and pressure profiles. Therefore; the objective of this research is to quantitatively compare and assess these thermal and fluid parameters through an experimental study approach and Computational Fluid Dynamics (CFD) simulation. The methodology involves direct measurement of temperature and pressure parameters under low and high-temperature conditions; which are then processed to determine the convection coefficient (); heat transfer rate (); and heat flux (). The main findings indicate that at low-temperature conditions; the heat transfer coefficient () was found to be 53.26 ; the heat transfer rate () was 24.99 W; and the heat flux () was 537.87 ; with a pressure drop of 0.86 Pa. In conclusion; thermal conditions play a crucial role in determining the dynamics of air flow and the efficiency of heat transfer; the greater the temperature difference (); the higher the potential heat transfer rate; establishing a strong correlation between thermal conditions and the convection phenomenon.

Chronic Obstructive Pulmonary Disease is a chronic respiratory disease characterized by progressive and not fully reversible airflow limitation. Dyspnea is the primary symptom experienced by COPD patients and significantly affects their quality of life, especially among those hospitalized. This condition may lead to activity limitation, psychological distress, and decreased social functioning. This study aimed to determine the relationship between the level of dyspnea and the quality of life of COPD patients in the pulmonary inpatient ward of Cut Nyak Dhien General Hospital Meulaboh. This study employed an analytical design with a cross-sectional approach. The sample consisted of hospitalized COPD patients selected using purposive sampling. Dyspnea severity was measured using the Modified Medical Research Council (mMRC) scale, while quality of life was assessed using the St. George’s Respiratory Questionnaire (SGRQ). Data were analyzed using the Spearman correlation test to determine the relationship between variables.The results showed that most respondents experienced moderate to severe dyspnea and had poor quality of life. Statistical analysis revealed a significant relationship between dyspnea level and quality of life (p < 0.05) with a negative correlation.In conclusion, there is a significant relationship between dyspnea severity and quality of life in COPD patients, where higher dyspnea levels are associated with lower quality of life.

Asthma is a heterogeneous disease characterized by chronic inflammation of the airways and respiratory symptoms such as wheezing, shortness of breath, chest tightness, and cough, which vary over time in both frequency and severity. This condition is accompanied by limitations in expiratory airflow, which can be either reversible or persistent. In asthma patients, especially those treated in the Emergency Department (ED), a common nursing problem is ineffective airway clearance due to mucus accumulation and bronchospasm. One strategy to address this is the administration of warm drinking water, aimed at improving airway clearance. The design used in this final nursing scientific paper is a qualitative case study with an intervention of warm water intake. The subjects of this study consisted of 3 asthma patients in the ED, and the intervention was conducted from January 3-11, 2026, at the Emergency Department of Charitas Hospital Km.7 Palembang. Airway clearance was measured before and after the intervention, which involved giving 200 ml of warm water at 38ºC, without a control group. After the intervention, all three patients showed improved airway clearance, indicated by more effective coughing, decreased sputum production, reduced wheezing, improved breathing patterns, and improved respiratory rate. The implementation of this evidence-based practice (EBP) is expected to provide additional information regarding the use of nonpharmacological therapy, specifically the administration of warm drinking water, in asthma patients with ineffective airway clearance.
