Hyperbaric Oxygen Therapy Exam 2026 – Complete Practice Test

Before starting HBOT, you need a careful safety check because the therapy uses high-pressure oxygen and can reveal or worsen health issues. The essential pre-treatment step is a comprehensive medical history and physical examination that looks for contraindications and flags any risks, with focused evaluations of the ears, nose, and sinuses (ENT) and of lung function as indicated. This broad approach ensures you don’t miss problems that could make HBOT unsafe, such as conditions that would bar treatment or require additional management.

ENT status matters because pressure changes during HBOT can cause barotrauma to the ears or sinuses. If there’s a history of recurrent sinus disease, nasal obstruction, or Eustachian tube dysfunction, the clinician may need to optimize these areas before therapy or adjust the plan. Pulmonary function is important because underlying lung disease or structural issues (like bullae) can raise the risk of complications from high inspired oxygen levels or pressure changes; testing is done when the history or exam suggests risk to gauge suitability or to tailor precautions.

A broad evaluation covers all these areas rather than isolating one domain. Skipping the evaluation or relying on a single factor could miss safety concerns, whereas a thorough history and exam with targeted ENT and pulmonary assessments as indicated provides the safest path to HBOT candidacy.
