GR SYSTEM D.O.O. is one of the leading European developers and manufacturers of innovative equipment for longevity. The headline product is the device for interval hypoxic-hyperoxic training OXYTERRA RS.
 
The method of interval hypoxic-hyperoxic training is widely used in prevention, treatment, and rehabilitation, as well as for overall health improvement and rejuvenation, weight reduction, increased stress resilience, and the extension of active longevity. It also helps sportspeople to reach endurance and performance.

This technology promotes mitochondrial renewal (cell’s power plants) and triggers regeneration, health optimization, and rejuvenation processes at the cellular level. The underlying mechanism of cellular adaptation to oxygen was recognized by the 2019 Nobel Prize in Physiology or Medicine.
 
The innovative OXYTERRA RS system enables a course of interval hypoxic-hyperoxic training, during which the patient alternately breathes (via a breathing mask) gas mixtures with reduced oxygen content (7-16%) in hypoxia mode, normal oxygen content (21%) in normoxia mode, and elevated oxygen content (25-33%) in hyperoxia mode. The procedure is absolutely safe.
The key distinguishing feature of OXYTERRA RS is its personalized approach. It enables the creation and real-time adjustment of an individual treatment protocol during the procedure, based on the patient’s medical history, current physical condition, heart rate, and oxygen saturation.
 
Functional modes for personalized protocols (OXYTERRA RS):
• Hypoxia-Hyperoxia. Standard breathing therapy mode.
• Hyperoxia-Hypoxia (Inversion). Recovery mode for weakened patients. Inversion normalizes saturation before the hypoxic phase and allows training even for complex patients with low baseline saturation, which is not possible with other devices.
• Hypoxia-Normoxia. Mode for patients with contraindications to high oxygen concentrations and for specific training protocols.
• Prolonged Hyperoxia. Enriched-oxygen breathing mode.
• Hypotest. Automatic determination of the individual starting oxygen (%) level for the hypoxic phase.
• Biofeedback. Automated training based on biological feedback (heart rate and saturation control).
• Manual and automatic modes.
 
OXYTERRA RS uses a modern, eco-friendly membrane air-separation technology to maintain precise O2 concentration at each training phase according to set parameters (fluctuations not exceeding 0.5%), and the 4steps filtration system.
 
Areas of application: Corporate wellness, Cosmetology, Sports, Fitness, Cardiology, Pulmonology, Neurology, Physical and Rehabilitation Medicine, Obstetrics and Gynecology, Mitochondrial and Preventive Medicine, Endocrinology, Aesthetic Medicine and Cosmetology, Pediatrics, Geriatrics, Addiction Medicine.
