Oxygen Concentrator is an electronic device that provides Oxygen to the patients by concentrating room air (ambient air) into pure oxygen.
The air we breathe is mainly comprised of Nitrogen (78%) & Oxygen (21%). This machine takes the room air using a compressor, removes Nitrogen from it and delivers medical grade Oxygen up to 95% purity.
How does it work?
The basic working of an Oxygen Concentrator is simple; it takes room air, removes Nitrogen from it and gives us medical grade O2 up to 95% purity.
Since Nitrogen and Oxygen are two main components of air with 78% Nitrogen and 21% Oxygen; the air is left with 90-95% pure Oxygen after removing Nitrogen from it.
Types
Stationary Oxygen Concentrator:
Staionary concentrator also known as home oxygen concentrator is the one which works only on AC mains. All stationary Oxygen Concentrators deliver continuous flow of Oxygen just like a cylinder with standard delivery systems.
Portable Oxygen Concentrator:
They are similar to home oxygen concentrators but smaller in size, lighter in weight, easy to carry and can work on battery as well as AC mains. Most portable models are pulse flow based but some have continuous mode as well.

Humidifier
Flow of Oxygen through the airways tends to dry them up just like normally air would do to any wet surface. In order to avoid the dryness in nose and throat of patients, a humidifier is required.
O2 Delivery systems
Most commonly used O2 Delivery Sytems are: Nasal Cannula and Simple face Mask. However other than these two, some other less common systems are non-rebreathing mask, partial re-breathing mask, Trans-tracheal catheter and Ventury mask.
Nasal cannula
O2 is delivered directly to nostrils through a thin tube called Nasal cannula which is connected to the source by one end and the other end is splitted into 2 prongs & is placed in nostrils.
Simple face mask is a single patient use plastic mask which is to be placed on the face of patient covering nose and lips for respiration.
