Technologies for improving quality of life
At GR SYSTEM, everything revolves around technologies for improving quality of life. This is not only our slogan, but also our main goal.
We are an innovative company specializing in the development and implementation of advanced solutions that help improve quality of life.
Our goal is to create technologies that support a high quality of life and human health.
What is hypoxic-hyperoxic therapy?
Hypoxic-hyperoxic therapy is a non-invasive method based on controlled alternation of breathing phases with reduced oxygen content — hypoxia — and increased oxygen content — hyperoxia.
This activates processes that optimize energy production at the cellular level.
Origin of the method
The method of cellular training has been developed since the 1980s for preparing pilots and astronauts for extreme altitude conditions. Today, the technology is actively used in elite sports and medical rehabilitation.
How does it work?
Controlled stress
Alternating air with low oxygen content — 7–16% — and high oxygen content — 25–33% — creates controlled oxidative stress.
Cellular renewal
Mitochondria, the energy stations of cells, are protected from stress, while damaged and aging mitochondria are eliminated.
Regeneration impulse
A short-term energy deficit after the session signals the body to accelerate the production of new, healthy mitochondria.
Result
Cells become more resistant to stress, and energy production increases more steadily.
Who benefits from IHHT?
Biohacking
Body optimization and support for healthy aging.
Sport
Faster recovery after physical effort and improved endurance.
Health
Rehabilitation support, including after viral illnesses, and vascular strengthening.
Anti-age
Improved skin quality and stress reduction.
IHHT therapy is accessible to everyone — regardless of fitness level or age.
Oxyterra: technology created by us
The studio works with devices of our own production.
This guarantees medical-level precision of settings and world-class safety.
We do not just use the technology — we develop it.
SpO₂ monitoring and automated control
The device screen displays blood oxygen saturation in real time. The closed-loop system continuously adjusts oxygen concentration based on the patient's SpO₂ value — guaranteeing that individual target ranges are never exceeded.
OXYTERRA RS
The OXYTERRA RS device is a technological solution that implements interval hypoxic-hyperoxic training at a new level of safety and efficiency.
Advantages of OXYTERRA RS
Intelligent cellular training
The procedure works like cellular fitness, targeting the root of many chronic conditions — cellular energy production.
Automated control
During the session, blood oxygen saturation — SpO₂ — is continuously monitored. The closed-loop system automatically adjusts parameters.
Comfort and safety
Unlike altitude training, the procedure takes place in a relaxed position at normal atmospheric pressure.
Scientific foundation
The method is based on the Nobel Prize-winning discovery of cellular oxygen sensing mechanisms — the HIF pathway — and is supported by numerous clinical studies.
Individual protocols
Protocols can be precisely adjusted to each patient's goals — from prevention to rehabilitation.
Reliability and durability
A unique engineering solution ensures exceptional reliability, making OXYTERRA RS a distinctive solution on the market.
