Mometrix Media LLC Prepare to Fail Miserably! Outdated, Unrelated and Blatantly Incorrect information on the flashcards! Beaumont Texas

As a proctor of the CHT exam, as well as contributor to writing some of the test questions, I can tell you this material will offer you a limited generic history of HBO, much of which is not included in the exam.

The instructions for test application; preparation and rules to become a CHT and CHRN that come from the NBDHMT resource manual are adapted into many of the flashcard questions. I assure you those details ARE NOT incorporated into the CHT exam. That accounts for about 20 questions.

The flash card set I reviewed was from 2012, however the authors quote only NFPA 99 from the 1999 edition. Three more editions have been out since and the current CHT exam refers to codes applicable to the 2012 edition of NFPA99. So they discuss codes that may no longer apply.

A blatant error on one-flashcard states Oxygen is Flammable! Oxygen is a component to the fire triangle but left alone, Oxygen it is not flammable! Anyone who reads that card and doesn’t understand it’s incorrect will surely miss that test question on the CHT exam.

This study set says it is specifically for CHT exam applicants. However, there are approx. 15-20 flashcards that relate to the BNA's exam process and nursing standard care aspects for the CHRN. None of those questions are on the CHT exam.

Things are over generalized like stating something like: Oxygen % in the chamber must be controlled due to the risks of the fire. Well duh! But the CHT exam is going to ask what is the maximum allowable percentage of oxygen inside the Class A chamber. The answer is 23.5% but the flashcard isn’t going to tell you that! Same with all the NFPA 99 requirements for amps, voltage, fire suppression requirements, high pressure valves, wiring and other limits on allowables in the chamber.

The flashcards are really no more of a study tool than reading the free NBDHMT resource manual that tells you to refer to resources like NFPA, and other known textbooks like Workman and Kindwall.

The cards cover a lot of details on treatment protocols, however our industry cannot seem to agree on any one protocol therefore the CHT exam DOES NOT test on protocols with the exception of understanding how to run a DCS treatment table 5 and 6. Of course the flashcards do not discuss how we do that slow (1psi/min) ascent in a chamber.

There is no information about safety for the inside attendants who acquire DCS while working with patients however we need to know this for the exam.

The TCOM information is either unhelpful or inaccurate. Practice problems for dive scenarios with bottom time factors and gas laws would have been helpful to be included.

Responding to a hyperbaric patient emergency or complication (like when to stop compression or emergently decompress) is a huge focus for the CHT exam however, again the flashcards do not cover any specifics other than stating the tech should be prepared for the unexpected!

There are many cards with extra irrelevant information that you would be wasting a lot of time on trying to understand yet never see in a CHT exam or apply in a HBO setting. Clearly a clinical minded team did not write this nor did they bother to have someone proof the material. They simply copied and pasted details (from the internet perhaps) and threw it down on note cards, slapped a hefty charge on it and made promises that you can't dispute like "guaranteed to raise your test score!" Unless this is your second time taking the exam, how do know if it raised your score? I feel sorry for the folks that invest into only this material as test prep because I can almost guarantee you failure!
