Abstract
The goal of this study on silent monitoring alarms is to make the Neonatal Intensive Care Unit (NICU) quieter with the help of a context sensitive clinical monitoring alarm system. A work domain analysis in the NICU of Máxima Medical Centre in Veldhoven, the Netherlands, reveals that more than half of the monitoring alarm events occur when a nurse is treating the infant at the incubator in while the nurse is paying full attention to the infant. This provides an opportunity for silent lighting alarms. The proposed intelligent system detects whether the nurse is treating the infant at the incubator or not and changes alarm modality to light or audio accordingly. This intelligence based on level of attention does not require complex judgments on clinical relevancy of the alarms or optimization algorithms. The results of the work domain research and an experiment show that the proposed solution has potential to improve the alarm system at the NICU, but the success is heavily dependent on the design details, which thus reserve further attention.
