For labs and clinics

Gas exchange, wherever you test.

VenTracer is being built for sports-science labs, coaches and longevity clinics who want measured VO2max and thresholds without a cart. Here is what to expect and how we will prove it.

In practice

Built around how you already test.

FIELD TESTING

Take the lab outside.

Test on the track, the court, the water or at altitude, in the sport the athlete actually does.

SIDE BY SIDE

Check it against your cart.

Pilot labs run VenTracer alongside their own reference system, so you can judge agreement for yourselves.

RAW DATA

Every breath, exportable.

Time, flow, gas fractions and derived values per breath, ready for your own analysis tools.PRELIM

THROUGHPUT

Short set-up, many athletes.

A fit-and-seal check and a room-air reference before each test, then straight into the protocol.PRELIM

CLINIC ROOM

No dedicated lab needed.

A mask, a phone or tablet, and a bike or treadmill. Useful wherever VO2max is part of a fitness consult.

REPORTS

Readable by athletes and clients.

VO2max, thresholds, zones and fuel mix in a report you can hand over the same day.

The partnership

What you get, and what we ask.

Terms are agreed with each partner before any unit ships. This is what we expect them to cover.PRELIM

Units
Engineering units and a mask fit kit, before anyone else. You get
Support
Direct access to the engineering team during your tests. You get
Data
Raw breath-by-breath export from every session you run. You get
Methods
A say in protocols and analysis before the study design is fixed, and acknowledgement in the publication. You get
Side by side
Tests run with VenTracer and your own reference system on the same athletes. We ask
Time
A set of sessions over a few months, scheduled around your lab. We ask

Validation

We'll prove it before we claim it.

Accuracy claims wait for data. Here is the plan we will be held to.3

Reference
A laboratory metabolic cart, tested on the same athletes. Planned
Protocol
Rest, then an incremental ramp to exhaustion. Planned
Statistics
Bland–Altman bias and limits of agreement, plus intraclass correlation. Planned
Thresholds
VT1 and VT2 compared with thresholds picked from the cart by experienced physiologists. Planned
Publication
Full results published before any accuracy figure appears on this page. Committed

What VenTracer can't do (yet)

  • We haven't published validation data. Until we do, treat readings from early units as experimental.
  • Thresholds need a proper ramp test. Short or broken-up sessions may not show a clear VT2.
  • A leaking mask makes the numbers wrong. The app will check the seal before every test.
  • It isn't a medical device and can't diagnose anything.4
  1. Now · 2026

    Concept and architecture

    System design, sensing plan, industrial design and brand.

  2. 2027

    Engineering prototypes

    First working analyzers on the bench and on athletes.

  3. 2027

    Validation pilot

    Engineering units tested side by side with partner labs' reference systems.

  4. After validation

    Wider pilot

    Units for coaches, athletes and clinics, once results are published.

Become a validation partner.

We are looking for a small number of labs and clinics to test early units against their own reference equipment.
