Your breath shows how well your body works
A non-invasive test at our Bucharest clinic: you wear the PNOĒ mask, breathe normally, and the device analyses every breath. You learn how your metabolism, heart, lungs and cells are working, and get a nutrition and training plan built on your own data.
- No needles, no blood draw
- Results explained by a specialist
One test, useful for any health goal
Whether you want to lose weight, perform better at your sport or live longer and healthier, the starting point is the same: how your body uses oxygen and fuel.
Weight management
A slowing metabolism is the number one reason diets fail. The test shows how many calories you really need and which fuel you burn.
Athletic performance
Oxygen flow through the lungs, heart and cells is the hallmark of performance. Find out what holds you back and which heart-rate zones to train in.
Longevity
How oxygen flows through the lungs, heart and cells is the strongest predictor of longevity and of chronic disease risk.

What the PNOĒ test measures
By analysing the oxygen you take in and the carbon dioxide you breathe out, PNOĒ calculates up to 23 metabolic and cardiorespiratory markers.
- Metabolism
- How many calories you burn at rest and during exercise.
- VO2 max
- Your maximum capacity to use oxygen, a key marker of longevity.
- Fat and carb burn
- Which fuel your body uses, and at what intensity.
- Cellular function
- How efficiently your cells turn oxygen into energy.
- Heart and lungs
- How well the two systems work together.
- Biological age
- How old your body really is, compared with your age on paper.
- Training zones
- The heart-rate ranges in which training is most effective for you.
- Breathing mechanics
- Your breathing rate and efficiency, which can limit exercise.
- Nervous system
- The balance between stress and recovery.
Lab-grade accuracy in a lightweight mask
PNOĒ is a portable breath gas analyser. Its oxygen and carbon dioxide flow sensors work breath by breath, and the manufacturer reports independent validation showing the same accuracy as the clinical analysers used in hospitals.
- O₂ and CO₂ flow sensors
- Breath-by-breath analysis
- 23 metabolic and cardiorespiratory markers
- Non-invasive: no needles, no blood draw

The resting test (RMR) shows how your metabolism works at rest. The active test (AMR) shows how your body responds to effort.
Both tests: resting and active
- 2 tests: RMR (resting) and AMR (active)

Read our story →Frequently asked questions
Is the test invasive or painful?
No. You wear a light mask and breathe normally. There are no needles, no blood draw and no radiation.
How long does the test take?
The measurement itself takes a few minutes. The exact length depends on the type of test, and we tell you how much time to set aside when you book.
What is the difference between the resting and the active test?
The resting test (RMR) measures how many calories your body burns at rest and which fuel it uses. The active test (AMR) shows how these values change during effort and sets your training zones and VO2 max.
How do I prepare for the test?
We send you the preparation instructions when you book.
How often should I repeat the test?
It depends on your goal. A new test after a few months usually shows how your metabolism and fitness have responded to the plan.
Who is the test for?
Anyone who wants to understand their metabolism: people who want to lose weight, amateur or competitive athletes, and anyone interested in prevention and longevity.
