Respiratory therapists are medical workers and typically work in a hospital or similar healthcare facility setting. They care for patients with emphysema, asthma, bronchitis, pneumonia, chest trauma, and cardiac failure. When working with patients, they conduct an examination to gain an understanding of any existing breathing issues that the patient may have. This examination may be as simple as a conversation-style interview, or it may be slightly more in-depth with various diagnostic tests. Once they have an understanding of the potential respiratory issues or risks, the respiratory therapist works with a physician to develop a patient treatment plan. Similar to other medical professionals, respiratory therapists are expected to work with their patients throughout the entire treatment process: monitoring, recording, and evaluating their progress.
