Abstract
Background: CPAP has been shown to be particularly beneficial in the management of acute cardiogenic pulmonary edema by reducing both preload and afterload, thus decreasing the work of breathing and improving oxygenation.
Methods: This study was a prospective observational study, conducted in the period from 2022 to 2024, assessing the effectiveness and safety of prehospital CPAP therapy use in patients with acute cardiogenic pulmonary edema, administered alongside standard care.
Results: In this study, 50 patients with acute cardiogenic pulmonary edema were treated by physician-led emergency teams in the Canton of Sarajevo. CPAP significantly improved clinical parameters across all time points. Systolic blood pressure decreased from 151.0 ± 41.0 mmHg at initial contact to 138.4 ± 32.0 mmHg before transportation and further to 130.2 ± 28.5 mmHg upon hospital admission (p < 0.001). Diastolic pressure dropped from 85.6 ± 17.2 mmHg to 81.1 ± 15.2 mmHg before transportation (p = 0.018), with a slight further decrease to 80.2 ± 13.9 mmHg (p = 0.083). Heart rate fell from 114 ± 26.4 bpm to 111.3 ± 24.9 bpm before transportation (p = 0.003) and finally to 99.5 ± 18.2 bpm before hospital admission (p < 0.001). Respiratory rate decreased from 31.0 ± 10.2 to 28.0 ± 10.5 breaths/min (p = 0.002) and further to 22.6 ± 7.3 breaths/min (p < 0.001). End-tidal CO2 levels increased from 28.0 mmHg (23.5; 33.5) to 30.0 mmHg before transportation (p < 0.001), and to 35.0 mmHg (32.0; 37.5) before hospital admission (p < 0.001). Oxygen saturation improved from 79.0% (72.0; 81.0) to 84.0% before transportation (p < 0.001) and reached 94.0% (91.0; 98.2) before hospital admission (p < 0.001). VAS scores for dyspnea significantly dropped from 8.0 (6.0; 8.2) at initial contact to 6.0 (4.0; 8.0) before transportation (p < 0.001) and further to 4.0 (3.0; 5.0) before hospital admission (p < 0.001), indicating substantial symptom relief. ECG findings remained stable throughout the intervention.
Conclusions: Prehospital CPAP therapy significantly improved clinical outcomes in cardiogenic pulmonary edema, including reductions in blood pressure, heart rate, respiratory rate, and enhanced oxygenation and symptom relief. These findings support its broader use in emergency care, even during short transport times.
