Day-to-Day Responsibilities of a Respiratory Therapist

Understanding what respiratory therapists actually do on the job provides important context for why the education and training timeline is structured the way it is. The role requires a balance of technical skill, clinical judgment, and patient interaction.

Respiratory therapists are responsible for assessing patients with breathing disorders and implementing appropriate treatments. This often begins with reviewing a patient’s medical history, evaluating symptoms, and performing a physical assessment. From there, therapists may recommend or initiate therapies based on physician orders and clinical findings.

Common responsibilities include administering oxygen therapy, delivering aerosolized medications, and managing airway clearance techniques. In more critical settings, therapists play a key role in managing patients on mechanical ventilation, adjusting settings, monitoring responses, and assisting with weaning.

They are also trained to respond to emergencies such as respiratory failure or cardiac arrest. In these situations, respiratory therapists often assist with intubation, provide ventilation support, and participate in rapid response or code teams.

In addition, they perform diagnostic procedures such as pulmonary function tests and arterial blood gas analysis. These tests help evaluate lung function and guide treatment decisions.

Note: Because of the complexity of these responsibilities, the educational process is designed to ensure that graduates are prepared to handle a wide range of clinical scenarios safely and effectively.

Skills Required to Succeed in Respiratory Therapy

The time it takes to become a respiratory therapist is not only about completing coursework. It also involves developing a specific set of skills that are essential for patient care. One of the most important is clinical competence.
