Credentialed Practitioners By State

Member Directory

Over 440,000 respiratory care practitioners have earned NBRC credentials in the United States and abroad, as of December 31, 2017. The following table shows how many CRT, RRT, CPFT, RPFT, NPS, SDS, and ACCS credentials have been awarded to respiratory care practitioners in each of the 50 states, Guam, Puerto Rico, and the Virgin Islands.

When reviewing the “Total Practitioners” column, it is important to note that many practitioners hold multiple credentials. For example, all RRTs are also recognized as CRTs, and all RPFTs are also recognized as CPFTs. Similarly, all Neonatal/Pediatric Respiratory Care Specialists and Sleep Disorders Specialists are also recognized as CRTs and/or RRTs, and all Adult Critical Care Specialists are also recognized as RRTs. The “Total Practitioners” column approximates the number of individual practitioners who reside in a state and is not a summation of the credentialed national groups.

In addition to the information provided for each state, Guam, Puerto Rico and the Virgin Islands, we also have record of approximately 2,300 credentialed practitioners who reside in other countries or have U.S. military overseas addresses.

The information presented in the following table is based on the most current address information in the NBRC database. Please keep us informed if you move so we can update your address. You may also change your address online at
