Pulmonologist vs. Respiratory Therapist: What’s the Difference?

Respiratory care is an important field of medicine — it literally helps keep people breathing. If you’re interested in working in this field, you may be exploring what type of role is right for you.

To assist you in your research, we’re highlighting the difference between two common roles in respiratory care: a pulmonologist and a respiratory therapist. Keep reading to learn the differences in what these two medical professionals do, where they work and what is required to start these careers.

Pulmonologist vs. Respiratory Therapist: Comparing Roles

What does a pulmonologist do?

A pulmonologist is a physician who specializes in diagnosing, treating and managing conditions
related to the respiratory system, such as those affecting the lungs, throat or windpipe.

Pulmonologists treat more serious respiratory conditions, including but not limited to:

Pulmonologists frequently coordinate with other medical professionals such as cardiologists, pathologists, nurses and respiratory therapists to help patients access the level of care they need.

When treating patients, a pulmonologist may conduct physical exams, order and interpret lab tests and imaging, prescribe medications and more. Though they generally don’t perform surgeries, pulmonologists can perform biopsies.

While pulmonology is its own specialty within internal medicine, pulmonologists may choose to specialize their practice even further, such as by focusing on a specific condition (e.g., pulmonary fibrosis or COPD) or on a certain patient population (e.g., pediatric or geriatric pulmonology).

What does a respiratory therapist do?

A respiratory therapist (RT) is a licensed medical professional who provides evaluation, treatment and care for people who have breathing challenges such as asthma, COPD or lung disease. An RT may apply breathing treatments directly or teach the patient to perform treatments on their own at home.

Respiratory therapists work with patients of all ages, from newborns with underdeveloped lungs to elderly individuals with advanced respiratory conditions.

According to the California Employment Development Department’s Occupational Profile for respiratory therapists, respiratory therapist duties include:
