Registered Pulmonary Func-tion Technologists

What is NBRC?

The National Board for Respiratory Care (NBRC) Inc. is a non-profit organization formed in 1960 with the

purpose of awarding and maintaining credentialing for Respiratory Therapists in the United States. The NBRC is the only organization in the United States which develops certification examinations

for Registered Respiratory Therapists (RRTs) and Certified Respiratory Therapists (CRTs). The NBRC also offers additional specialization credentialing for respiratory practitioners that hold

its certifications. The CRT and RRT designations are the standard credential in respiratory care for li-

censure requirements in the portions of the United States that have enacted a Respiratory Care Act.

States that license respiratory therapists sometimes require the practitioner to maintain their NBRC credentialing to maintain their license to practice. The NBRC is headquartered in Olathe, Kansas. It has been in the Kansas City metropolitan area since 1974. Both the NBRC and Applied Measure-

Question No 10:

A helium dilution test has just been performed on a patient. The following results areobtained:FRC 5.0 LVC 4.0 LERV 1.5 LTLC was calculated to be 6.0 L by plethysmography. From this information, a pulmonaryfunction technologist should conclude that the patient

A. Had inadequate intrapulmonary mixing of inspired gas, resulting in an erroneous FRC.B. Did not perform the slow vital capacity properly, resulting in too low an FRC by he-liumdilution.C. Was turned into the helium dilution circuit at a lung volume considerably above FRC.D. Did not remain in the helium dilution breathing circuit long enough for equilibration.
