When we buy an oxygen concentrator, we will encounter this problem: Should we buy a continuous oxygen supply or a pulse oxygen supply? What is the difference between them? What is the difference in use? Let's learn about it together today!

About the operation mode

Continuous oxygen supply means that the machine will always output oxygen regardless of whether we inhale or not. The oxygen utilization rate of this oxygen supply method is low. Oxygen can only enter the body when we inhale, and the oxygen during exhalation is directly wasted.

The pulse oxygen supply mode supplies oxygen according to the frequency of our breathing. This mode can accurately sense human breathing, prepare oxygen supply at the end of exhalation, supply oxygen instantly when inhaling, and suspend oxygen supply when exhaling, reduce impact resistance, which is equivalent to free breathing, and has a higher oxygen utilization rate. DEDAKJ portable medical oxygen concentrator adopts the pulse oxygen supply mode. In addition to comfortable oxygen inhalation, the oxygen utilization rate is as high as 99%.

About the difference in effect

If we are using medical oxygen concentrators, when the oxygen flow rate and oxygen concentration are the same, the oxygen obtained is medical oxygen with an oxygen concentration of more than 90%, and the effects of the two modes should be the same.

However, if the continuous oxygen concentrator is used for a long time, the nostrils will dry out, so water needs to be added to moisten the oxygen to alleviate the problem of dry air. The pulse oxygen concentrator does not have this problem.

If a health-care oxygen concentrator is used, the concentration of oxygen will decrease as the flow rate increases.

About application scenarios

Most desktop oxygen concentrators on the market use a continuous oxygen supply mode. Desktop oxygen concentrators use mains electricity to operate. Users need to breathe oxygen while sitting or lying down, and the body is large and bulky and cannot be moved. It is mostly used for medical/home fixed oxygen inhalation.

Pulse oxygen supply is mostly used in portable oxygen concentrators. This oxygen supply method consumes less power and can extend the battery life. It is suitable for portable oxygen concentrators to go out and replenish oxygen.

The DEDAKJ portable medical oxygen concentrator is a typical pulse oxygen concentrator. It uses pulse dose oxygen supply, provides comfortable breathing, weighs only 1.5 KG (including battery), and has a battery life of up to 4 hours + 4 hours (rechargeable lithium battery), which can meet the oxygen supply needs of various mobile scenarios such as outdoor activities, plateau mountaineering, driving tours, etc.
