Diving Physics, Pressure & Gas Behavior – DMR – D2

Description

Diving physics pressure gas behavior is a focused module in the Trilogy EMS Diving Medical Responder curriculum. Applies Boyle's, Dalton's, Henry's and Charles's laws quantitatively to a diver. Covers unit conversion across fsw, msw, ata, psi, bar and mmHg; volume change with depth and why the shallowest 33 feet carry the greatest fractional change; partial pressures on air and nitrox; inert gas loading and off-gassing; gas density and the work of breathing; and altitude exposure after diving.

The module connects diving-specific knowledge to practical assessment, decision-making and field management. Students are expected to recognize the relevant mechanism, identify important findings, collect and communicate a useful dive history, and understand how the information affects care and referral. The material emphasizes accurate terminology, repeatable assessment, appropriate documentation and communication with EMS, emergency department and hyperbaric resources when indicated.

Diving physics pressure gas behavior is designed to strengthen the responder’s ability to interpret diving incidents in context rather than treating an isolated symptom. The course reinforces the relationship between dive profile, physiology, patient presentation, treatment priorities and transport decisions. Content is presented within the student’s existing scope of practice; completion does not expand or replace professional licensure, medical direction or agency protocols.

This module is part of the Trilogy EMS Diving Medical Responder (DMR) course and supports the integrated knowledge required to assess and manage diving and aquatic emergencies. Students should complete the module content and associated assessment as assigned within the DMR curriculum.
