Choosing the Right FeNO Platform: Why Workflow Matters in Modern Clinical Practice

Fractional exhaled nitric oxide (FeNO) testing is no longer an emerging tool - it is an established component of respiratory assessment. Clinical guidelines from organizations such as the American Thoracic Society and the Global Initiative for Asthma recognize FeNO as a valuable adjunct for evaluating airway inflammation when used alongside clinical history, symptoms, and other diagnostic measures.

As FeNO adoption grows, clinics are no longer asking whether to use FeNO - they are asking which platform best supports efficient, real-world care. Increasingly, that answer depends on workflow.

From Measurement to Practical Use

When clinics evaluate new devices, the real differentiators aren't theoretical features, they're the day-to-day factors that impact patients, staff, and overall efficiency. A modern FeNO system needs to do more than measure a biomarker; it needs to fit seamlessly into real clinical life.

Fenom Flo™ was developed with these operational realities in mind.

1. Breath Accessibility: Supporting a Broader Patient Population

Not every patient can perform long or complex breathing maneuvers. Pediatric patients, older adults, and individuals experiencing symptoms may struggle with sustained exhalations, limiting the feasibility of testing.

Fenom Flo™ directly addresses this challenge as the only portable FeNO device approved for a 6-second breath test in adults and pediatric patients ages 7 years and older. This shorter, simpler breath maneuver helps expand access to FeNO testing across a broader range of patients - without adding time or complexity to the visit.

2. Workflow Efficiency: Designed to Keep Clinics Moving

FeNO testing should support clinical flow, not slow it down. Systems that require frequent calibration or complex sensor handling can disrupt schedules and place additional burden on staff.

Fenom Flo™ is designed to minimize operational friction, with no daily calibration required and a user-replaceable NO sensor. By reducing maintenance demands, Fenom Flo helps staff focus on patient care while supporting smoother, more predictable workflows.

3. Portability: Bringing FeNO Testing to the Point-of-Care

Respiratory assessments don't always happen in one location. With its compact, handheld design, Fenom Flo™ enables FeNO testing in exam rooms, procedure areas, and satellite clinic spaces - bringing measurement directly to the patient, not the other way around.

This flexibility supports efficient care delivery in busy and space-constrained clinical environments.

4. Connectivity and Consistency

As FeNO testing becomes more routine, clinics increasingly value platforms that support consistent data capture and integration into existing workflows. Fenom Flo™ is designed to support repeatable measurement and seamless use across providers and visits.

5. Manufacturing Reliability: Supporting Continuity of Care

Reliable access to diagnostic tools is essential for maintaining consistent care. Fenom Flo™ is engineered and manufactured in the United States, supporting controlled production, stable inventory, and dependable access to equipment and supplies.

For clinics, this reliability translates into fewer disruptions and greater confidence in long-term planning.

The Biomarker Is the Same. The Experience Is Not.

As FeNO testing becomes standard practice, differentiation lies not in the biomarker itself, but in how easily testing fits into daily clinical care.

Fenom Flo™ was designed to deliver objective FeNO measurement in a way that supports patients, clinicians, and clinic workflows alike. For practices investing in FeNO technology, the right platform isn't just about measurement - it's about making testing practical, accessible, and consistent in the real world.
