Abstract: Objective: To explore the emotional responses of emergency department (ED) nurses to participating extracorporeal cardiopulmonary resuscitation (ECPR). Methods: Using a phenomenological qualitative research approach, semi-structured interviews were conducted with 12 ED nurses experienced in adult ECPR. The interview data were analyzed using Colaizzi′s seven-step method to extract themes and sub-themes. Results: Four primary themes and ten sub-themes were identified including a strong need and expectation for learning about ECPR, a positive attitude and willingness to participate in and implement ECPR, a clear vision for the future development of ECPR and profound emotional experiences related to ECPR. Conclusion: ED nurses have strong learning needs, positive attitudes, and clear suggestions regarding ECPR, along with profound emotional experiences. Enhancing training and education on ECPR-related knowledge, skills, and protocols is crucial for improving ED nurses′ ability and confidence in participating in ECPR.
