The software

From raw pressure to clinical result

SpiroWright turns the signal from a pneumotachograph into acceptable, repeatable manoeuvres and the numbers a clinician reads - FVC and its derivatives, flow-volume and volume-time curves, predicted values, and a clean report. Built on a Wright/Fleisch hybrid pneumotach with bidirectional flow handling, drift compensation, and 3-litre syringe calibration.

Built by R. E. Wright and R. Wright - 70 years' combined experience in spirometry, founders of IQTeQ and AME.

SpiroWright for Windows

Version 1.2.25 · x64 · Windows 10/11

Why Windows may warn you the first time. Windows only trusts an installer that carries a paid code-signing certificate — an annual fee charged every year, for every product, whether or not a single doctor downloads it. We have chosen not to pay it and not to pass it on to you: that money stays out of your token price. The trade-off is that Windows may show “Windows protected your PC” on first run. Choose More info → Run anyway. You are not taking our word for it: every release publishes its SHA-256 checksum at ame.tech/version.json, so you can verify the file you downloaded is byte-for-byte the one we built, which is a stronger guarantee than a certificate alone.

Spirometry software in South Africa - frequently asked questions

SpiroWright by Advanced Medical Engineering (AME), Cape Town: ATS/ERS 2019, GLI-2022, occupational health, pricing and support.

What is SpiroWright?

SpiroWright is clinical spirometry software for Windows 10/11 (x64) from Advanced Medical Engineering (AME), Cape Town. It runs on the AME / IQTeQ pressure-pneumotach USB sensor (HEXAR Core) and delivers flow-volume and volume-time curves, FEV1 / FVC / PEF / FEF25-75, ATS/ERS 2019 acceptability and repeatability grading, GLI-2012 and GLI Global 2022 z-scores, BTPS correction and multi-page HTML / PDF / PNG / CSV reports.

How much does SpiroWright cost in South Africa?

The download is free. Every verified account starts with 1000 free tokens (about 20 tests at 50 tokens per test) and tokens never expire. After that you pay per test through encrypted PayFast checkout in rands - no subscription. For HEXAR Core sensor pricing, email [email protected].

Is SpiroWright compliant with ATS/ERS 2019?

Yes. SpiroWright applies the ATS/ERS 2019 acceptability and repeatability criteria to every effort, grades the session, records 3-litre syringe and motor calibration, and the sensor accuracy is verified against ISO 26782. Reports show the flow-volume loop, z-score bars and the acceptability matrix.

Which reference equations does SpiroWright use?

GLI-2012 (LMS) and the race-neutral GLI Global 2022 equations, reported as z-scores, lower limit of normal (LLN) and percent-predicted, with the reference-equation source cited on the report.

Is SpiroWright suitable for occupational health and medical surveillance?

It is built for South African occupational-health practice: periodic medical-surveillance testing, pre/post-bronchodilator and patient-history comparison, HIV / TB / pack-year patient fields, SAMA procedure codes and ICD-10 suggestions, practice-branded QR-verified reports and CSV export for your records.

Does SpiroWright need an internet connection?

No - it is offline-first and load-shedding-aware: tests, reports and patient data work locally on your PC. Internet is only needed to sign up, verify your email, buy tokens and receive updates.

Can I use my existing AME / IQTeQ spirometer with SpiroWright?

Yes. SpiroWright runs on existing AME / IQTeQ sensors on any Windows PC - no new device is required. It adds AI-assisted interpretation (obstructive / restrictive / mixed patterns, severity, GOLD staging, lung-age estimate), ATS/ERS-graded reporting and modern analytics to hardware you already own.

Where is AME based and how do I get support?

Advanced Medical Engineering (AME) is based in Cape Town, South Africa, with local South African support by email at [email protected]. spirowright.com, iqteq.com and advancedmedicalengineering.com all lead to ame.tech.
