Reviews ALS field management of diving injuries: pressure physics and physiology, DCS and arterial gas embolism, barotrauma, the injured-diver assessment with dive-profile history and focused serial neuro exam, high-flow oxygen…

Reviews recognition-to-treatment management of unstable and stable dysrhythmias: tachycardia and bradycardia algorithms, synchronized cardioversion, transcutaneous pacing with capture verification, AV block recognition, and management of torsades and hyperkalemia rhythms.

Covers human factors for the ALS team: error-chain models, closed-loop communication and graded assertiveness, cognitive biases in field diagnosis, checklists and cognitive offloading, and brief-execute-debrief structure for high-acuity calls.

Provides an ALS-facing orientation to hyperbaric oxygen therapy: mechanisms, emergency indications, monoplace versus multiplace capabilities, contraindications including untreated pneumothorax, patient preparation, and regional capability in destination decisions.

Covers ALS pharmacologic management of the ACS spectrum, acute heart failure phenotypes with nitrate and NIPPV strategy, early recognition and support of cardiogenic shock, and destination selection for reperfusion and…

Describes the expanding paramedic role beyond 911: MIH/CP program models and evidence, readmission reduction, alternative destination concepts, and the design of time-critical systems of care for trauma, stroke, STEMI, and…
