On a daily basis, pulmonary function technicians prepare patients for testing, explain the procedures in simple terms, and ensure that each test is performed correctly. They administer breathing exercises and use specialized equipment to measure lung function. After the test, they carefully record results and pass the data along to physicians for interpretation. Because the tests require patient cooperation, these technologists must combine technical skill with good communication and reassurance.

They are commonly employed in hospitals, pulmonary clinics, and diagnostic centers. In these settings, they work alongside respiratory therapists, pulmonologists, and other members of the healthcare team. Their role can be particularly important in clinics where patients with chronic breathing problems receive ongoing care and monitoring.

Certification is often preferred by employers and can enhance career opportunities. Many pulmonary function technicians earn the Certified Pulmonary Function Technologist (CPFT) credential, which demonstrates professional competence and adherence to industry standards.

In 2025, salaries for pulmonary function technicians typically range from $55,000 to $70,000 per year, depending on experience, location, and setting. Those working in large hospital systems or with advanced training may earn at the higher end of this scale.

The job outlook for pulmonary function technicians is positive. With respiratory conditions such as asthma and COPD becoming more prevalent, there is a growing need for accurate lung function testing. This ensures a steady demand for skilled professionals in the field, making it a stable and rewarding healthcare career.
