PHMC is approved as an introductory course in hyperbaric medicine by the Undersea & Hyperbaric Medical Society and the National Board of Diving and Hyperbaric Medical Technology.

This activity meets the UHMS and NBDHMT minimum requirements including 40 hours of face-to-face instruction.

The academics of this intensive course cover the spectrum of hyperbaric equipment and care. Topics include: physics of hyperbaric medicine and the gas laws; pharmacological effects of hyperbaric medicine; decompression theory and proper use of US Navy Dive tables; operational and fire safety; safety codes and standards; hyperbaric systems and ancillary equipment; ethics; side effects and contraindications; and patient selection and treatment of the UHMS accepted indications. The practicums include hyperbaric facility operation and proper use of transcutaneous oximetry equipment.
