A typical day for an RPFT involves performing a variety of pulmonary function tests, such as spirometry, lung volume measurements, and diffusion studies, to assess patients' respiratory health. You'll interact directly with patients, explaining procedures and ensuring their comfort and safety throughout the testing process. Collaboration with physicians, nurses, and other healthcare providers is essential as you relay test results and assist in diagnosing respiratory conditions. Additionally, you will maintain testing equipment, calibrate devices, and document results accurately in patient records. The role is both patient-facing and highly technical, providing a rewarding blend of clinical interaction and diagnostic expertise.
