The code blue system consists of a team formed specifically to treat patients with emergency conditions who are often referred to as the code blue team. But this system is inseparable from problems that sometimes pose challenges for the code blue team and the hospital. Objective: The aim of this study was to explore the experiences of nurses when become a member of code blue team. Research Methods: This research was a qualitative study using an interpretive phenomenological approach. Participants in this study were 8 people who were coded blue nurses at Wava Husada Hospital. The participants were selected using purposive sampling technique. The method used in this study is an in-depth interview supported by a guide to semi-structured interviews and open-ended questions. Results: The results of this study obtained 3 themes, namely: 1) nurses who have limited knowledge and skills; 2) long taken decisions by family; 3) application of the code blue system has not been maximized. Many factors make code blue nurses feel difficult when they have to do help on patients in the room. The difficulty comes not only from the patient's family, but also from nurses, and from the code blue management system at the hospital. Conclusion: Nurse as a member of code blue team must be able to provide optimal service in the midst of difficulties they sometimes feel. However, they went through that difficulty, in order to save the lives of their patients.
