Certified Hyperbaric Technologist Practice Test 2026 – Comprehensive Exam Prep

The individual credited with establishing oxygen tolerance limits in humans is Behnke. He conducted significant research in the area of hyperbaric medicine and physiology, particularly focusing on the effects of increased partial pressures of oxygen on human beings. One of his key contributions was understanding the toxicity of oxygen when exposed to pressures greater than normal atmospheric levels, particularly the central nervous system and pulmonary effects. His work laid the foundation for safe practices in hyperbaric therapy, helping to define the limits within which oxygen can be safely administered in various clinical scenarios.

Understanding oxygen tolerance is crucial for the safe application of hyperbaric treatments and for preventing toxicity associated with elevated oxygen levels. This aspect of hyperbaric medicine continues to be central to the training of hyperbaric technologists and practitioners. The other individuals mentioned in the options contributed to the field in different ways, but it is Behnke's contributions that are specifically recognized concerning oxygen tolerance limits.
