Objectives:
1-Improving the on time presence of the cardio-pulmonary resuscitation team at the patients’ bedside immediately following the cardio-pulmonary resuscitation code announcement
2-Increasing the outcome of the resuscitation by improvement of the cardio-pulmonary resuscitation teamwork
3-Applying the new method (musical alarm) as a standard method for announcement of the cardio-pulmonary resuscitation code in hospitals
Design:
Single blind clinical trial study
Setting and conduct:
After agreement of the executive directors of the hospital, the research process will be expressed to interns, residents, nurses, and who is in duty to announcing the cardio-pulmonary resuscitation codes (annunciator) in explanatory sessions. During study, all actual-CPR codes will be conventionally announced (verbally-code 99) and three other maneuver-CPR codes will be daily scheduled to announce. The time and the type of these announcements (verbal or musical- verbal codes) will be determined by block randomization method. It should be considered that the cardiopulmonary resuscitation team members are not aware about this decision, and they suppose that all kind of CPR code announcements have the same massage . Following the announcements, the persons who are present at the ward will check the team members’ presence and fill the checklist and also interview with them.
Participants:
Cardiopulmonary resuscitation team members including resident, intern, anesthesia technician, and nurses will be enrolled in the study.
Intervention:
In case group, the cardio-pulmonary resuscitation codes will be announced by the musical-verbal announcement rather than the verbal (code 99).
Variables:
CPR team members’ delay time, the announcement audibility rate (musical-verbal and verbal announcements),the announcement agitability rate
