PFT software helps clinicians meet the 2026 ATS/ERS standards by implementing real-time quality grading and automated “Grade A” through “Grade F” assessment for each manoeuvre. These updated guidelines require precise measurement of the back-extrapolated volume to be less than 5% of the FVC or 100mL. The software provides immediate visual feedback; this reduces the need for repeat testing by 15% and ensures your lab results meet international diagnostic benchmarks.
