Lesson 3 • Respiratory Physiology for Divers

Examines pulmonary mechanics, gas exchange, and ventilatory control under hyperbaric conditions. Links normal respiratory function to the pathological states encountered in diving.

Lesson 4 • Breath-Hold Diving Physiology

Covers the physiology of apnea, including oxygen stores, CO2 tolerance, and shallow-water blackout. Provides essential context before introducing compressed-gas diving pathology.

Lesson 1 • Mask, Suit, and Dental Barotrauma

Addresses less critical but clinically relevant squeeze injuries to the face, suit, and teeth. Reinforces the universal application of pressure principles across all gas-containing spaces.

Lesson 2 • Ear and Sinus Barotrauma

Details middle-ear, inner-ear, and sinus squeeze presentations, grading, and treatment protocols. Directly applies pressure physiology to the most common clinical injuries seen in divers.

Lesson 3 • Emergency Response to Barotrauma

Establishes field assessment and stabilization protocols for barotrauma victims prior to definitive care. Prepares students to act decisively in remote or boat-based diving environments.

Lesson 4 • Pulmonary Overpressure Accidents

Covers arterial gas embolism, pneumothorax, mediastinal emphysema, and subcutaneous emphysema from lung overexpansion. Connects pulmonary anatomy to life-threatening ascent injuries.

Lesson 1 • Differential Diagnosis of DCS

Trains systematic differentiation of DCS from arterial gas embolism, inner-ear barotrauma, and other conditions. Reduces misdiagnosis errors that delay life-saving recompression therapy.

Lesson 2 • DCS Prevention and Risk Reduction

Addresses dive planning, ascent rates, safety stops, and individual risk factors that modify DCS probability. Equips students to advise divers on evidence-based risk mitigation strategies.

Lesson 3 • Recompression and Hyperbaric Therapy

Covers hyperbaric oxygen treatment tables, chamber operations, and adjunct therapies for DCS. Connects clinical diagnosis to the definitive treatment pathway.

Lesson 4 • Clinical Presentation of DCS

Describes Type I and Type II DCS signs and symptoms across musculoskeletal, neurological, and cardiopulmonary systems. Enables accurate field diagnosis and urgency classification.

Lesson 1 • In-Chamber Emergency Management

Covers fire, oxygen toxicity seizures, cardiac arrest, and equipment failure inside the chamber. Prepares students to respond to life-threatening events in a pressurized environment.

Lesson 2 • Wound Care and Non-Diving Indications

Introduces hyperbaric oxygen therapy for wound healing, carbon monoxide poisoning, and other approved indications. Broadens students' clinical scope beyond diving-specific applications.

Lesson 3 • Patient Preparation and Monitoring

Details pre-treatment assessment, contraindication screening, and in-chamber vital sign monitoring. Connects clinical evaluation skills to safe hyperbaric therapy delivery.

Lesson 4 • Standard Treatment Tables

Covers the most widely used hyperbaric treatment tables for DCS and arterial gas embolism, including depth and time profiles. Enables students to select and execute appropriate treatment protocols.

Lesson 1 • Mixed Gas and Rebreather Hazards

Covers hypoxic mixtures, hyperoxic exposures, and contaminant gases in compressed air and mixed-gas systems. Prepares students to evaluate gas quality and equipment safety for technical diving.

Lesson 2 • Oxygen Toxicity Mechanisms

Explains central nervous system and pulmonary oxygen toxicity, their thresholds, and triggering factors. Establishes the physiological basis for oxygen exposure limits used in dive planning.

Lesson 3 • Carbon Dioxide Toxicity

Examines CO2 retention causes, hypercapnia symptoms, and the interaction between CO2 and oxygen toxicity. Addresses skip breathing and equipment factors that elevate CO2 in divers.

Lesson 4 • Nitrogen Narcosis

Describes the mechanisms, depth thresholds, and performance impairment caused by nitrogen narcosis. Connects narcosis awareness to safe depth limits and gas mix selection decisions.

Lesson 1 • Immersion Pulmonary Edema

Addresses the distinct syndrome of immersion pulmonary edema, its triggers, and management in divers. Differentiates this condition from drowning and near-drowning for accurate field diagnosis.

Lesson 2 • In-Water Rescue Techniques

Covers safe approach, tow techniques, and spinal precautions for conscious and unconscious aquatic victims. Establishes the physical rescue skills that precede all resuscitation interventions.

Lesson 3 • Resuscitation of Drowning Victims

Details current resuscitation guidelines adapted for drowning, including ventilation priority and hypothermic arrest. Connects drowning pathophysiology to evidence-based CPR modifications.

Lesson 4 • Post-Rescue Assessment and Monitoring

Covers secondary survey, pulmonary edema monitoring, and criteria for hospital observation after near-drowning. Prepares students to manage the delayed complications that follow initial resuscitation.

Lesson 1 • Framework for Dive Medical Evaluation

Establishes the purpose, scope, and regulatory context of dive medical examinations for recreational and professional divers. Provides the structural foundation for all subsequent evaluation sections.

Lesson 2 • Pulmonary Fitness to Dive

Addresses spirometry interpretation, asthma, bullous lung disease, and pulmonary contraindications. Connects respiratory physiology to the risk of pulmonary overpressure accidents.

Lesson 3 • Special Populations in Dive Medicine

Examines fitness considerations for older divers, diabetics, pregnant women, and divers with disabilities. Prepares students to apply individualized risk assessment beyond standard protocols.

Lesson 4 • Neurological and ENT Evaluation

Covers neurological conditions, seizure disorders, vestibular function, and ENT anatomy relevant to dive fitness. Directly links neurological and ENT pathology to barotrauma and DCS risk.

Lesson 1 • Autopsy and Forensic Considerations

Addresses post-mortem findings specific to diving fatalities, including gas emboli, drowning markers, and equipment analysis. Prepares students to collaborate with forensic pathologists on diving death investigations.

Lesson 2 • Prevention Programs and Safety Culture

Covers evidence-based prevention interventions, safety briefing design, and organizational safety culture development. Translates investigation findings into actionable programs that reduce future accident rates.

Lesson 3 • Epidemiology of Diving Accidents

Presents global diving fatality and injury data, common accident patterns, and high-risk activity categories. Establishes the evidence base that drives investigation methodology and prevention priorities.

Lesson 4 • Accident Investigation Methodology

Covers structured investigation frameworks, evidence collection, witness interviewing, and equipment examination. Provides the procedural toolkit for systematic post-accident analysis.
