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, no matter if you're breathing in or not.
Continuous flow is best for people who need a constant supply of oxygen, while pulse flow is ideal for portable units because it uses less energy and helps the battery last longer.
What is a nebulizer and nebulizer therapy?
What is a nebulizer and nebulizer therapy?
The Serene 5 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. It’s suitable for all ages and works by delivering medicine straight to your lungs for faster relief and better treatment.
