Understanding the proper concentration – or density – of oxygen is essential for safe, reliable and effective oxygen therapy. Whether used at home or on the go, your oxygen machine must always provide oxygen of the correct purity and flow rate to meet your medical needs. In this article, we’ll explain why oxygen concentration matters, compare different types of devices, and introduce you to the VARON VP-2 Pulse Portable Oxygen Concentrator – a lightweight, high-performance device designed for freedom, safety and consistent oxygen delivery.
Why is oxygen concentration important?
The natural composition of air is about 21% oxygen and 78% nitrogen. For people with conditions such as COPD, asthma or pulmonary fibrosis, this oxygen level is not enough. Low blood oxygen levels (hypoxemia) can cause fatigue, dizziness and even organ problems.
An oxygen concentrator increases the oxygen density of the air by filtering out nitrogen and providing oxygen with a purity of up to 90-95% – similar to hospital care. This ensures that the body receives enough oxygen to function optimally without overdose.
In oxygen therapy, purity and flow rate determine the effectiveness of the treatment. Too little oxygen will not alleviate symptoms, while too much oxygen can cause toxicity. Therefore, it is essential to use a high-quality, medical-grade device that provides stable oxygen delivery and maximum safety.
