1-5L Portable Pulse Oxygen Concentrator,Rechargeable,Demolished Battery, 93 % High Concentration Oxy

What is Pulse Dose? Being different from conventional continuous flow oxygen concentrators, pulse dose oxygen concentrators deliver oxygen on inhalation, this type of oxygen flow is ideal for treating respiratory conditions that do not require a high LPM (liters of oxygen delivered per minute). The benefit of a pulse dose oxygen concentrator is that it works with your breathing needs as they change, you get oxygen at your own pace. Furthermore, pulse dose oxygen concentrators are small, compact and lightweight so they are also easy to take along for daily activities.
