As a CPFT, you will commonly work in hospitals, outpatient clinics, or pulmonary function testing labs, performing tests to evaluate lung function in patients. Daily responsibilities include administering and interpreting spirometry and other pulmonary tests, maintaining equipment, educating patients about procedures, and documenting test results for the healthcare team. You can expect close collaboration with pulmonologists, respiratory therapists, and other allied health professionals to support patient diagnosis and treatment. This is a highly patient-focused role that requires both technical accuracy and effective communication skills. Over time, CPFTs can also expand their expertise into supervisory, teaching, or advanced respiratory care positions.
