ABEM UHM

UHM is an ABEM subspecialty certification, so candidates are physicians pursuing it on top of primary emergency medicine certification. Specific eligibility pathways, training requirements, and application deadlines are set by ABEM and can change. Verify your individual eligibility on ABEM's official subspecialty pages before you build a study timeline around an exam date.

The UHM subspecialty exam is a multiple-choice examination. ABEM does not publish item counts, timing, or scoring details on the pages available to us, so we do not state them here. Confirm the current format, appointment length, and any breaks directly with ABEM when you schedule, and practice with timed blocks so pacing is not a surprise on exam day.

Most candidates find it demanding because it blends basic physiology and physics with clinical management, and because many emergency physicians have limited day-to-day exposure to chamber operations. The questions reward conceptual fluency over memorized lists. Expect to reason through pressure–volume and gas-tension problems rather than simply recall indications for hyperbaric oxygen therapy.

Start with diving physics and physiology: gas laws, pressure and volume relationships, inert gas uptake and elimination, bubble formation, and the mechanisms of barotrauma and decompression illness. These concepts are prerequisites for understanding both undersea clinical problems and hyperbaric treatment rationale. Only after that foundation should you drill indications, protocols, and complications.

Our practice bank splits content evenly across Undersea Medicine, Hyperbaric Medicine, Diving Physics and Physiology, and Clinical Management of Diving and Hyperbaric Emergencies. That even split is a study-planning heuristic for this site, not an official ABEM blueprint. Use it to avoid over-investing in one area, but treat the official ABEM content outline as authoritative.

Frequent errors include confusing decompression sickness with arterial gas embolism, mismanaging the return-to-depth decision, applying oxygen-toxicity limits incorrectly, and forgetting that a deteriorating diver may need recompression rather than more surface resuscitation. Another common trap is memorizing hyperbaric indications without knowing the underlying mechanism the question is testing.

There is no ABEM-published preparation timeline, so build one around your own baseline. A practical approach is several months of steady work: a physics and physiology block, a clinical block, then repeated timed mixed sets with review of every missed item. Candidates who have not worked in a chamber should budget extra time for operational and safety content.

ABEM sets retake policy, waiting periods, and any associated requirements. We do not state those rules here because they are not documented in the source material available to us. Check ABEM's official policies and your MyABEM account for the current retake process before assuming a timeline for a second attempt.
