Registered Respiratory Therapist (RRT)

A respiratory therapy specialist is responsible for helping those who suffer from respiratory and pulmonary conditions and disorders. Their daily tasks include examining patients with breathing or cardiopulmonary disorders, performing diagnostic tests like lung capacity and nasal capabilities, and treating patients for chest physiotherapy and aerosol medications. In addition to monitoring, recording, and communicating patient progress, respiratory therapists consult with physicians to draft and develop patient treatment plans and teach clients and patients about medication, equipment, and prognostic treatment plans.

Apart from these essential duties, respiratory therapy specialists work collaboratively with respiratory physicians and other healthcare professionals to ensure that patients receive the best care possible. Certified respiratory therapy specialists are a class of healthcare workers that have come into high demand. There is currently an ever-growing need for the specialized, certified skill set of respiratory therapists. These jobs exist at all levels of healthcare—especially as awareness of pulmonary health and the relationship between pollution and the environment increases, so too will the demand for specialized respiratory care.

Respiratory therapists test the lung capacity of patients by guiding their breath into diagnostic instruments as well as taking blood samples. These samples are submitted for tests and help pulmonologists and their teams best treat patients with specific respiratory conditions. Respiratory therapists are physiotherapy experts, removing mucus from patient lungs, treating patients with cystic fibrosis, and offering relief from pain and discomfort. RRTs might also work in a home-care capacity, educating patients and their families on how to use ventilators, life-support systems, and other medical devices related to pulmonology. They are also experts in supporting patients attempting to quit smoking and those dealing with sleep apnea and other respiratory disorders.

In some cases, respiratory therapists are employed in an on-call capacity. In this role, they inspect ventilating equipment, check homes for environmental hazards, and discuss ways to alleviate symptoms with family members suffering from respiratory difficulties.

Read on to learn more about respiratory therapy, including a step-by-step guide on how to become a part of this growing, exciting industry.

Admissions Requirements for Respiratory Therapy Programs

In terms of admissions requirements for students interested in careers in respiratory therapy, a background in the health sciences, healthcare administration, human health, wellness, or psychology are prime places to begin. University bachelor’s programs in respiratory therapy typically require completion of approximately 120 credit-hours of undergraduate work in respiratory therapy or a related field. Most respiratory therapy professionals hold associate degrees; however, a bachelor’s degree can position students favorably to increase their earning potential.

Respiratory Therapy Program Accreditation & Certification

The vast majority of respiratory therapy programs are accredited by the American Association for Respiratory Care (AARC). The Commission on Accreditation for Respiratory Care (CoARC) oversees most programs in the country for respiratory therapy. The National Board for Respiratory Care (NBRC) is also a wonderful resource and accredits domestic programs, too.

To ensure one’s program of interest is accredited, all aspiring respiratory therapists are encouraged to ensure the school is at least regionally accredited by an organization recognized by the Commission for Higher Education Accreditation (CHEA).

How Long Does it Take to Become a Respiratory Therapist?

To become a respiratory therapist requires a minimum of one year of schooling, with up to four years if pursuing a bachelor’s degree. Expect an additional six months to one year of study to become AARC-certified, plus a variable number of years in clinical respiratory therapy experience depending on the type of professional certification sought.

How To Become a Respiratory Therapist – Step-by-Step Guide

Becoming a respiratory therapy specialist, as mentioned above, should take a minimum of about one year, and up to as many as seven if prospective respiratory therapy professionals take longer to gain clinical experience, industry experience in real-life settings, or an undergraduate degree.

Step 1: Graduate High School

As a high school student, a focus on the subjects of the health sciences, physiology, biology, natural sciences, and healthcare will help to build a solid foundation for courses of study in respiratory therapy.

Step 2: Earn an Undergraduate Degree (One to Four Years)

Earn a one-year respiratory therapy diploma or a two-year associate’s degree in respiratory therapy.

Aside from the more general education requirements, gaining a four-year bachelor of science (BS) in respiratory therapy science is ideal, but degrees in health services and healthcare administration can also provide the necessary skills. Regardless, certification as a respiratory therapist will be required before a student can claim the title.

Step 3: Gain Work Experience (One Year or More)

One way to advance a career as a respiratory therapist is to gain work experience in the healthcare industry itself. This should help you to prepare for certification and more advanced positions, which are typically necessary to qualify for positions in upper management or as clinical directors.

Step 4: Become a Certified Respiratory Therapist (Timeline Varies)

The AARC offers two principal credentials for respiratory therapists: the Certified Respiratory Therapist (CRT) and the Registered Respiratory Therapist (RRT). Consult the AARC for more information on how and when to recertify as per state and federal regulations.
