HERMES: Quality and Safety of Advanced Respiratory Support During Patient Transport

The HERMES Phase III study is an international, multicenter, prospective observational investigation designed to characterize the quality and safety of patient transport during advanced respiratory support. The study will enroll patients undergoing prehospital, interhospital, or intrahospital transport while receiving advanced respiratory support, including high-flow nasal oxygen (HFNO), noninvasive ventilation (NIV), or invasive mechanical ventilation, as determined by routine clinical practice. The study protocol will not assign respiratory-support modalities, transport strategies, or therapeutic interventions. The primary objective is to prospectively evaluate clinical, technical, organizational, and transport-related factors associated with the safe continuation of respiratory support throughout patient transport. Data collection will include patient characteristics, respiratory-support modality and settings, transport characteristics, physiologic monitoring, transport-team composition, oxygen and electrical power resources, equipment-related events, interruptions or modifications of respiratory support, clinical deterioration, rescue interventions, escalation of respiratory support, and other transport-associated adverse events. HERMES Phase III constitutes the prospective multicenter component of a broader research program that previously included an international survey of respiratory-support transport practices and an exploratory prospective feasibility evaluation of portable external power during ambulance transport.
