ABPM Undersea and Hyperbaric Medicine study plan
ABPM Undersea and Hyperbaric Medicine · Give each week a clear focus.
8 weeks · About 7 hours per week
Diving medicine and physiology
Compute absolute pressure, partial pressures, and gas density at 0, 10, 30, and 60 msw for air and for a trimix, showing each step of the arithmetic
Explain the mechanism of barotrauma in each gas-filled space (middle ear, sinuses, mask, gut, lung) and rank the spaces by how early symptoms appear during descent
Describe the oxygen–hemoglobin dissociation curve and predict how hyperbaric oxygen, hypothermia, and acidosis shift it
State the assumptions of the Haldane tissue-half-time model and explain why perfusion-limited and diffusion-limited tissues load inert gas differently
Draw the pressure–volume relationship for a breathing lung and explain how a breath held during ascent produces pulmonary overpressure
Your checkpoint
Closed-book 40-question quiz on pressure physics, gas laws, and barotrauma, scored at 80% or higher, with each missed item rewritten as a short teaching note
Diving medicine and physiology
Differentiate type I and type II decompression sickness and arterial gas embolism by onset, presentation, and exam findings
Trace the decision logic that leads from a suspected DCS or AGE presentation to recompression on a Treatment Table 6 versus a Treatment Table 4
Explain inert gas uptake and elimination during a multi-level dive and identify the dive profiles that most raise DCS risk
Contrast central nervous system oxygen toxicity with pulmonary and ocular oxygen toxicity in terms of dose, timing, and mitigation
Explain how a closed-circuit rebreather can deliver a hypoxic or hypercapnic gas and describe the physiological consequences of each
Your checkpoint
A written 10-case DCS/AGE triage worksheet stating initial diagnosis, recompression table selected, transport and hydration plan, and the reasoning for each
Hyperbaric oxygen therapy
Match each accepted hyperbaric oxygen indication to its mechanism of action (oxygen delivery, neutrophil function, angiogenesis, antimicrobial effect, bubble reduction)
Build a dosing reference that gives pressure, session length, and typical number of treatments for each indication you are responsible for
List absolute and relative contraindications and the specific management step for each before a patient enters the chamber
Explain the evidence standard used to grant and to withdraw an indication and identify indications that are investigational or not supported
Describe how transcutaneous oximetry and other baseline testing influence the decision to treat
Your checkpoint
A complete indication matrix covering every accepted indication, with mechanism, protocol, contraindication, and expected outcome, self-scored against published society position statements
Hyperbaric oxygen therapy & Diving medicine and physiology
Predict and manage the complications of therapy: barotrauma, oxygen toxicity, confinement anxiety, hypoglycemia, and fire risk from patient-carried items
Adapt a treatment plan for patients who cannot equalize, who are ventilator-dependent, or who have an artificial airway
Explain the rationale for air breaks and how they change the dose delivered
Critique the design of a study of hyperbaric oxygen in a contested indication and state what evidence would change practice
Your checkpoint
Timed 40-question case-based exam mixing domains 1 and 2, scored at 75% or higher, with a written error log grouped by cause
Hyperbaric chamber operations and safety
Explain the fire-safety triad inside a chamber and the specific controls applied to each leg before and during a pressurization
Sequence a full treatment: pre-dive patient and equipment check, compression, air breaks, decompression, and post-dive documentation
Describe the duties of the inside attendant, outside tender, chamber operator, and supervising physician and where authority transfers in an emergency
Explain gas supply requirements and purity limits, including how an inadequate or contaminated supply is detected
Write out the response to two chamber emergencies: fire inside the chamber and a patient who deteriorates while at pressure
Your checkpoint
A chamber-operation checklist plus two written emergency drills, reviewed line by line against the facility's operating manual and safety code requirements (ASME PVHO-1 and NFPA 99)
Occupational and environmental aspects of diving and compressed-air work
Apply fitness-to-dive criteria to a candidate with asthma, a seizure history, diabetes, or a cardiac condition, stating the disqualifying feature and the review pathway
Differentiate the roles of the regulating bodies, consensus standards, and employer programs that govern commercial, scientific, and recreational diving
Explain the decompression tables and work-rest practices used in compressed-air (caisson) work and how they differ from in-water diving schedules
Identify the occupational exposures of compressed-air work, including noise, thermal stress, fatigue, and dysbaric osteonecrosis
Interpret the exposure and medical-surveillance requirements an employer must meet for a compressed-air worker
Your checkpoint
A one-page fitness-to-dive decision aid plus three worked case dispositions, with citations to the specific standard or consensus guideline relied on for each
Diving medicine and physiology & Hyperbaric chamber operations and safety
Re-audit every error logged in weeks 1 through 6 and convert each into a one-line rule you can recall under time pressure
Practice integrating physiology with chamber operations by working through multi-step scenarios that begin with a dive and end with a treatment table
Rehearse the calculations most likely to appear on the exam (pressure, partial pressure, oxygen dose, gas consumption, decompression obligation) until each is completed in under two minutes
Identify the two weakest domains from practice scores and complete a targeted review of only those topics
Your checkpoint
A full-length 100-question practice exam scored at 75% or higher, with a written review of every missed question and the specific weak-domain plan for week 8
Hyperbaric oxygen therapy & Occupational and environmental aspects of diving and compressed-air work
Recite from memory the accepted indications, mechanisms, and protocols that were drilled in weeks 3 and 4
Rehearse the occupational and environmental standards that were drilled in week 6, focusing on fitness-to-dive thresholds and surveillance requirements
Complete two timed half-length exams under exam conditions and review only the errors
Assemble a one-page pre-exam summary containing the formulas, protocols, and decision rules you are most likely to forget
Your checkpoint
Two timed half-length exams at 75% or higher plus a finished one-page pre-exam summary sheet
