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 licensure 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.

function technologist is unable to adjust the
gain to the calibration gas concentration. Which

• Question No 10

A helium dilution test has just been performed on
a patient. The following results
are obtained FRC 5.0 L VC 4.0 L ERV 1.5 L TLC
was calculated to be 6.0 L by plethysmography.
From this information, a pulmonary function
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 helium dilution. 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. Answer A
