SUMMARY:Human Factors–Based User Interface Design of a Modular Hemodynamic
  and Bladder Monitoring System
DESCRIPTION:Yehwon Baek, Soyeon Noh, and Wonseuk Jang (Yonsei University)\
 n\nContinuous monitoring of hemodynamic status and bladder residual volume
  is essential for improving patient safety and postoperative outcomes. To 
 support integrated patient management, the CW30 modular monitoring system 
 was developed using patch-type ultrasound probes and artificial intelligen
 ce for continuous assessment of fluid responsiveness and bladder status. T
 his study applied a human factors–based usability engineering approach to 
 optimize the user interface (UI) design of the system. Two iterative forma
 tive evaluations based on IEC 62366-1 were conducted with healthcare profe
 ssionals experienced in patient monitoring. The first evaluation identifie
 d user preferences and potential use-related issues associated with module
  display modes, layout configurations, and multi-module screen arrangement
 s. Based on these findings, the UI was redesigned and assessed in a second
  formative evaluation. Results demonstrated that maintaining continuous vi
 sibility of core vital parameters while presenting module-specific informa
 tion as supplementary data was critical for clinical usability and patient
  safety. Preferences for integration differed by module type, reflecting v
 ariations in clinical workflow and application context. The findings suppo
 rt the effectiveness of iterative usability evaluation in developing safe,
  efficient, and clinically appropriate interfaces for modular medical devi
 ces.\n\n
