SG02L - Your Ideal Portable Oxygen Concentrator

How the pulse flow settings equal to continuous flow

Many clients are wondering how the pulse flow settings equal to continuous flow. The following formula might be helpful for you to understand:

Our bodies naturally inhale and exhale at rest in a 1:2 ratio. This means we inhale in 1/3 time. Under the model of 1-liter continuous flow, we only inhaled 1/3 oxygen (333ml) in one minute. Because pulse flow only deliver oxygen when inhale. So the pulse flow can be same effect as 1LPM by delivering that add up to 333ml oxygen in one minute of inhalation time. If pulse flow want to be equal to 2LPM, 3LPM, 4LPM and 5LPM, directly use 333ml multiply by a multiple.

Trade-off & Visible Effect:

To be lighter and have a longer battery time, old portable oxygen concentrators sacrificed oxygen dosage, reducing the dose from 333ml per pulse flow setting to 210ml. The difference may not be noticeable when the user's illness is mild. As the disease progresses and the need for oxygen increases, it becomes apparent that patients feel a lack of oxygen. There are many customers with illnesses that develop to moderate have reported this situation.

When designed the portable oxygen concentrator SG02L, we sacrificed weight and battery time and took sufficient oxygen (333ml/gear) as the core feature. Although SG02L will be 0.3 kg to 0.4 kg heavier, the treatment performance is better. It can reach truly effect of 1LPM to 5LPM, meeting the needs of different conditions. We think safety and reliability are more crutial for our clients. We believe that such a sacrifice is worth it.

Questionaire before Order:

Can we ask whether you buy it for family members or for personal?

If you buy for a family member, may I ask how old he is? What respiratory disease does he suffer from? How many liters of oxygen does he need right now?

The oxygen concentrator is used for health and life. The demand may vary in different situations. Usually, we need more oxygen in our daily activities, outdoor activities, and travel than sitting at home. Besides, your family member might need more oxygen as time goes by. We must consider them.

After receiving your reply, we will determine which model suits you give you our professional suggestions.
