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

Week 1

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

Week 2

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

Week 3

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

Week 4

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

Week 5

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)

Week 6

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

Week 7

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

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

Milestones

Week 2: Score 80% or higher on the domain 1 quiz and complete all 10 DCS/AGE triage cases correctly on the first pass

Week 4: Complete the full indication matrix and score 75% or higher on the mixed domains 1 and 2 case exam

Week 6: Complete the chamber-operation checklist, two emergency drills, and the fitness-to-dive decision aid, each reviewed against a standard or guideline

Week 8: Score 75% or higher on both timed half-length exams and finish the summary sheet with no blank entries
