Are you considering a career as a respiratory therapist? This field is not only rewarding but also essential in the healthcare system. Respiratory therapists (RTs) specialize in treating patients with respiratory issues, working with individuals from newborns to the elderly. If you have a passion for helping others and want to make a difference in the medical field, becoming a respiratory therapist might be the perfect path for you. In this guide, we’ll break down the necessary steps to embark on this fulfilling career.

Understanding the Role of a Respiratory Therapist

Before explaining the process of becoming a respiratory therapist, it is crucial to define what a respiratory therapist does. RTs are healthcare professionals who work with patients who have lung diseases and other related conditions including asthma, COPD, and heart failure. They also play an important role in patient and population education on the respiratory system and respiratory diseases.

Step 1: Have a Natural Desire to Help Others

The most significant trait of a respiratory therapist is the desire to assist people. Caring for patients who have pain and discomfort requires compassion and empathy. This career is not just a job; it is a chance to change people’s lives for the better.

Step 2: Graduate from High School

In order to become a respiratory therapist, one must first complete high school or obtain a GED. This is a precondition for any respiratory therapy program admission.

Step 3: Take Required Prerequisite Courses

Prerequisite courses vary by program but typically include:

• Anatomy and Physiology
• Chemistry
• College Algebra
• English Composition

To make sure you are well-prepared, check each school’s specific requirements.

Step 4: Apply to Accredited Respiratory Therapy Programs

Once you have finished the prerequisites, start looking for and applying to accredited respiratory therapy programs. Choosing the right program is important for your future career.

Step 5: Enroll in Your Chosen Program

Once you have been accepted, officially enroll in the program. This makes your spot and sets you on your path to becoming a respiratory therapist.

Step 6: Complete Required Coursework

Core courses include the following:

• Fundamentals of Respiratory Care
• Cardiopulmonary Anatomy and Physiology
• Patient Assessment
• Pharmacology
• Airway Management
• Mechanical Ventilation
• Neonatal and Pediatric Care
• Cardiopulmonary Pathology

These courses are essential for your future practice.

Step 7: Gain Clinical Experience

Clinical experience is essential and must be obtained. Most programs require between 500 to 1,000 clinical hours, which combine classroom instruction with practical training in hospitals or other medical settings.

Step 8: Graduate with an Associate’s Degree

Once you have finished your coursework and clinical hours, you will graduate with an associate’s degree in respiratory therapy, which is the minimum requirement for the profession.

Step 9: Pass the NBRC Credentialing Exams

In order to practice as a respiratory therapist, you must pass the National Board for Respiratory Care (NBRC) exams, the Therapist Multiple-Choice (TMC) exam and the Clinical Simulation Exam (CSE). These exams make you eligible to receive the Registered Respiratory Therapist (RRT) credential.

Step 10: Apply for State Licensure

Once you have received your credentials, apply for a license from the state in which you intend to practice. Each state has its own licensing procedure so it is necessary to check on the specificities.

Step 11: Apply for a Job

You are now licensed and credentialed and can begin applying for positions as a respiratory therapist. Post your search on job boards, check hospital websites and clinics that are close to you for job openings.

Step 12: Advance Your Career

With experience, you can apply for the specialty credentials that the NBRC offers such as:

• Adult Critical Care Specialist
• Neonatal/Pediatric Specialist
• Sleep Disorder Specialist
• Certified or Registered Pulmonary Function Technologist

Also, a bachelor’s or master’s degree in a related field can lead to management positions or research jobs.

Step 13: Maintain Your Certification

You must continue to meet the requirements of your credentials through continuing education units (CEUs) and periodic assessments to be able to practice. Not doing this can result in the loss of one’s license.
