improving respiratory status among patients with acute heart failure by implementing nursing guidelines

Background: patients with acute heart failure (ahf) often experience pulmonary congestion, leading to tachypnea, orthopnea, and hypoxia. nursing guidelines play a crucial role in relieving pulmonary congestion and improving respiratory function. thus, this study aimed to improve respiratory status among patients with ahf by implementing a nursing guideline at heart hospital.methods: a quasi-experimental research design was utilized in this study. this study (august 2023-september 2024) included 100 patients randomly assigned to intervention (n=50) and control (n=50) groups. the control group received routine care, while the intervention group received nursing guidelines focused on respiratory support, active range of motion, early mobilization, and 6-minute walk test. patients with comorbid chronic obstructive pulmonary disease (copd), coma (unconsciousness), pregnancy, or stroke were excluded. the data collection tool was a patient assessment tool (demographic data and arterial blood gases [abg]), a respiratory assessment tool (chest examination, chest sound assessment, and dyspnea scale), and a patientsꞌ outcomes tool (complication, mortality, and length of stay). data were analyzed utilizing spss software, version 22, with statistical significance set at p<0.05.results: compared to the control group, the intervention group showed significant respiratory improvement in arterial o2 saturation (sao2), accessory muscle use, crepitation, and chest infection (p=0.041, 0.004, 0.008, 0.026), as well as in complications, mortality, and length of stay (p=0.026, 0.023, 0.009).conclusion: nursing guidelines may improve respiratory outcomes in ahf; further multi-setting studies are recommended to confirm findings.
