Abstract

Integrated medical devices are crucial in critical care settings, where they monitor, assess, and intervene in patient care. However, these devices face significant design complexities, such as system integration, ensuring interoperability, managing human error, and preventing device failures. This paper explores the challenges related to the design and management of risks in integrated medical devices for critical care environments. Three research problems are discussed in-depth: managing device failures, ensuring interoperability in multi-vendor ecosystems, and mitigating human errors in high-pressure environments. The paper also provides strategies such as Failure Modes and Effects Analysis (FMEA), Human Factors Engineering (HFE), and system redundancy to address these issues, ensuring improved patient safety. The challenges and solutions are examined through case studies and real-world examples to underline the importance of risk management strategies and provide insights into future innovations.
