Respiratory therapists (RT) are trained to help people with lung diseases or disorders that can result from a myriad of issues. They treat patients dealing with pulmonary distress due to complications from asthma, bronchitis, COPD, pneumonia, chest trauma, prematurity, lung cancer, and more. They work with people of all ages, from infants to the elderly, in conjunction with physicians and nurses to come up with treatment plans aimed at best helping restore as much natural breathing function as possible. From initial interviewing and examining, to teaching patients how to administer treatments on their own, respiratory therapists are a critical component in helping people living with cardio-pulmonary disease and disorders.
