What is the difference between continuous flow and pulsed flow?
What is the difference between continuous flow and pulsed flow?
Pulse flow concentrators deliver oxygen only when you breathe in, saving power and extending battery life. On the other hand, continuous-flow concentrators provide a steady stream of oxygen, regardless of whether you're breathing in or not. Continuous flow is best suited for individuals who require a constant supply of oxygen, while pulse flow is ideal for portable units due to its lower energy consumption, which helps the battery last longer.
What is a nebulizer and nebulizer therapy?
What is a nebulizer and nebulizer therapy?
The NT-04 home oxygen concentrator comes with a nebulizer function. A nebulizer is a device used in breathing therapy to turn liquid medicine into a mist, which you can then inhale directly into your lungs.
This therapy is often used to treat conditions like asthma, COPD, cystic fibrosis, and others. Itโs suitable for all ages and works by delivering medicine straight to your lungs for faster relief and better treatment.
