简要总结
Heart failure is a leading cause of emergency department admissions, with dyspnea and psychological distress being among the most common presenting symptoms. This randomized controlled trial aims to evaluate the effect of nurse-guided diaphragmatic breathing and pursed-lip breathing exercises on dyspnea and psychological distress in patients presenting to the emergency department with heart failure. A total of 112 eligible participants will be randomly assigned in a 1:1 ratio to either an intervention group receiving breathing exercises in addition to standard care or a control group receiving standard care alone. Dyspnea severity will be assessed using the Modified Borg Dyspnea Scale, and psychological distress will be assessed using the Distress Thermometer at predefined time points. The findings are expected to provide evidence for the effectiveness of a simple, low-cost, nurse-led non-pharmacological intervention in improving symptom management in patients with heart failure.
详细描述
Heart failure is a major public health problem associated with frequent emergency department admissions due to symptoms such as dyspnea and anxiety. Dyspnea is one of the most distressing symptoms experienced by patients with heart failure and is often accompanied by increased anxiety, which may further worsen respiratory distress. Although pharmacological treatment remains the cornerstone of acute management, non-pharmacological interventions, including breathing exercises, may provide additional symptom relief.
The aim of this randomized controlled trial is to evaluate the effect of diaphragmatic breathing and pursed-lip breathing exercises on dyspnea and anxiety in patients presenting to the emergency department with heart failure.
A total of 112 eligible patients will be randomly assigned to either an intervention group or a control group. Participants in the intervention group will receive standard emergency department care in addition to nurse-guided diaphragmatic breathing and pursed-lip breathing exercises. The control group will receive standard emergency department care alone.
Clinical parameters, including pulse rate, blood pressure, respiratory rate, oxygen saturation, and distress level, will be assessed according to the study protocol. Dyspnea severity will be evaluated using the Modified Borg Dyspnea Scale, and anxiety-related distress will be assessed using the Distress Thermometer. Outcome measurements will be obtained at baseline and at predefined time points following the intervention.
The primary objective is to determine whether breathing exercises reduce dyspnea severity and anxiety compared with standard care. The findings of this study are expected to provide evidence regarding the effectiveness of a simple, low-cost, and nurse-led non-pharmacological intervention that may improve symptom management in patients with heart failure treated in emergency departments.

盲法说明
Due to the nature of the breathing exercise intervention, participants and the investigator delivering the intervention could not be blinded. To minimize bias, data were coded as Group A and Group B, and statistical analyses were performed by an independent statistician who was blinded to group allocation.
