Oxygen deprivation in enclosed spaces: risks and dangers

07/ 01/ 2026

Oxygen deprivation, or “hypoxia,” in enclosed spaces poses a serious threat to human health. Our brain needs about 20% of the total volume of oxygen absorbed to function properly. As soon as this indicator decreases by even a few percent, the body immediately begins to signal. The mass sealing of modern buildings significantly reduces the amount of fresh air in the room. What is oxygen deprivation? It is a condition in which the tissues and organs of the body do not receive enough oxygen or cannot absorb it effectively. The consequences of hypoxia can be serious, as oxygen is a key element for the normal functioning of the heart and brain. The main symptoms include: shortness of breath headache rapid heartbeat fatigue paleness of the skin and mucous membranes decreased concentration, memory, etc. The causes of hypoxia in enclosed spaces can vary, but one of the most common is high concentrations of carbon dioxide, which accumulates due to insufficient ventilation and prolonged inhalation of air contaminated with harmful chemical compounds. How to prevent oxygen deprivation? The most effective way is to ensure constant air exchange and maintain optimal oxygen levels in the room. PRANA ventilation systems with heat recovery help to solve this problem comprehensively. Our devices provide a constant flow of fresh air into the room while removing stale air, without mixing the air flows. Patented technology based on a copper heat exchanger allows you to retain up to 98% of the heat. This gives you fresh, oxygen-rich air without drafts or high energy costs. In addition, PRANA Eco Life series recuperators are equipped with special modern TVOC and CO2 sensors that monitor the level of carbon dioxide and volatile organic compounds (VOCs). Thanks to this, the system reacts to an increase in VOC and CO2 levels and automatically increases the supply of fresh air and removes polluted air when the indicators deteriorate. Taking care of the air in the room is just as important as taking care of your own health. After all, clean air is the key to comfort and well-being!
