Objective The purpose of this study was to identify the differences between the educational curricula, skill sets, and funds of knowledge required for certification as an Outdoor Emergency Care Technician (OEC-T), Emergency Medical Technician (EMT), and Emergency Medical Responder (EMR). Methods We directly and in detail compared topics and skills presented in the OEC-T curriculum with those presented in the EMT and EMR education and training curricula. Results The information and skills taught in the OEC-T curriculum are in general more extensive than those taught in EMR training but are not equivalent to EMT. The OEC-T program has more depth in environmental medical issues, such as altitude illness, hyperthermia and hypothermia. Completion of the EMR program is 112 hours shorter and constitutes 30% of the duration of the EMT program. Completion of the OEC-T program (for certification only and not including additional “on-hill” patroller training) is 80 hours shorter and is half the duration of the EMT program. Conclusions The OEC-T curriculum includes a skill set and fund of knowledge that exceeds those of the EMR program, but does not include all the knowledge needed for an EMT program. The OEC-T program prepares out-of-hospital providers to care for patients in the wilderness, with special emphasis on snowsports pathology. The EMT program places a greater emphasis on medical disease and emergency medication administration. These differences should be considered when determining staffing requirements for agencies caring for patients with snowsports pathology.

The mean optic nerve sheath diameter increased on ascent to high altitude compared to baseline values, but not to a statistically significant degree. The magnitude of the observed Δ optic nerve sheath diameter was positively associated with acute mountain sickness diagnosis. No such significant association was found between acute mountain sickness and diameter elevation above standard cutoff values, limiting the utility of sonography as a diagnostic tool.
