Perceived Usability of a Live Feedback Interface for Neonatal Ventilation Training

Abstract

During positive pressure ventilation (PPV), a careful balance of applied force must be administered to hold the face mask against an infant’s face. Applying too much force can hurt the child, while not enough force will contribute to insufficient air delivery and ineffective ventilation. Currently, there is no tool to assist clinicians in training with understanding the amount of force they should apply to the face mask to deliver effective PPV. Prior work has developed a sensor system and live-feedback interface to provide information about applied force to individuals training to learn PPV. This work assesses the perceived usability of the live-feedback interface using quantitative and qualitative analyses, including the System Usability Scale (SUS) questionnaire and verbal questions. Results from this study will help improve future iterations of this interface and can assist in other works seeking to develop training interfaces for use in hospital environments.
