Portable oxygen systems typically consist of two main components:
- An oxygen concentrator: The oxygen concentrator is a device that concentrates oxygen from the air.
- A delivery device: The delivery device is a device that delivers the oxygen from the concentrator to the patient. There are two main types of delivery devices: nasal cannulas and masks.
Nasal cannulas are two small tubes that fit into the patient’s nostrils. Masks cover the patient’s nose and mouth.
Portable oxygen systems are available in a variety of sizes and weights. Some portable oxygen systems are small enough to be carried in a backpack or purse. Others are larger and require a wheeled cart for transportation.
