Impact of Hemodynamic Events at Altitude on Outcomes for Critically Ill Patients
Abstract
Prior En Route Care (ERC) research evaluating the impact of air transport on combat wounded has analyzed in-flight hemodynamic events as binary outcomes based on handwritten data recorded on Critical Care Air Transport Teams (CCATT) medical records. These low frequency data are usually recorded at one-hour intervals, so the prevalence, severity, and duration of in-flight hemodynamic abnormalities remains a research gap. Insensitive data capture for in-flight events likely contributes to the conflicting results and clinical equipoise related to operational and medical decisions such as cabin altitude restriction (CAR) for critically ill combat wounded. Technology advancements enable direct download of hemodynamic parameters from Zoll Propaq monitors, which are currently in use by Critical Care Air Transport Teams (CCATT) as usual Patient Movement Items(PMI). Both commercial (COTS) and government off-the-shelf (GOTS) materiel solutions can enable electronic transfer of vital signs in the form of Zoll Case Review and Battlefield Assisted Trauma Distributed Observation Kit (BATDOK), respectively. This electronic data transfer will enable analysis of high frequency in-flight hemodynamic measurements.
