Oxygen therapy is known to give patients more energy, and reduce the risks of heart failure and lung disease. Those who take extra oxygen during exercise, perform better, and have less shortness of breath. Supplemental oxygen has also been shown to enhance user’s mental alertness and overall mood.

An oxygen concentrator takes in air and separates the oxygen from nitrogen, and then delivers it into a person via a nasal cannula. Air is 79% nitrogen and 21% oxygen. In respiratory infections that causes oxygen saturation levels to dip below 90%, having an external device supply pure oxygen eases the burden on the lungs. 

Protect & Shield™ Oxygen Generator consists of a compressor and sieve bed filter. The compressor squeezes atmospheric air and also adjusts the pressure at which is delivered. The sieve bed is made of a material called Zeolite that separates the nitrogen. There are two sieve beds that work to both release oxygen into a tank that’s connected to the cannula as well as release the separated nitrogen and form a continuous loop that keeps producing fresh oxygen.

The primary purpose of the oxygen generator is to take in air and then purify it before releasing the air to the user, ensuring that they have healthy, almost pure oxygen intake. It is suitable for middle-aged and elderly people, pregnant women, people with weak physique, and test students who have different degrees of physiological hypoxia. It can also be used to eliminate fatigue and quickly restore physical functions after heavy physical or mental exhaustion.

The oxygen generator uses high-quality molecular sieves as adsorbents to produce directly from the air through the pressure swing adsorption method (PSA).

The molecular sieve oxygen generator can provide oxygen that meets the oxygen concentration requirement of more than 90%. 

Negative ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress, and boost our daytime energy.
