Oxygen concentrators supply high levels of oxygen to patients using ambient air. They are commonly used in oxygen first aid and oxygen therapy, both of which require oxygen levels not commonly found in breathing air. Natural air is largely nitrogen, with about 21% oxygen mixed in. Oxygen concentrators remove nitrogen from the mix, elevating oxygen concentrations to about 95%. They are also used as alternatives to oxygen tanks, which use compressed oxygen and are highly flammable. Oxygen concentrators eliminate this risk by drawing from the surrounding air instead of a stored supply.
Maintenance information
Use your oxygen concentrator in well-ventilated areas to ensure a clean and steady air supply. Keep at least one window open when using the concentrator inside small rooms or cars. Keep the filters clean by washing them regularly. It is advisable to replace your filters or every year to keep them functional. Have your concentrator examined every year to check for leaks, cracks, or other damages. Rebuild or replace your compressor about once in five years.
These oxygen concentrators are freestanding and designed for high oxygen yields. They are commonly used in hospitals and clinics, but may also be purchased for home use. They usually have wheels or casters that allow them to be transported between hospital rooms.
Portable oxygen concentrators are more compact, with smaller reservoirs and lower oxygen yields. They are designed to be carried outdoors and usually come with carrying cases. They are often part of hospital first-aid sets.
Oxygen sensors: Choose an oxygen concentrator with a sensing device that alerts you when oxygen levels are too low. Look for one with indicator lights to help you monitor oxygen levels. Alarm indicators are ideal for concentrators used in public places, sucha s hospitals.
Airtight construction: Choose an oxygen concentrator with well-sealed tubes and tanks to prevent leaks. Make sure the casing closes completely and the tubes fit securely over the feeds. Check the side vents for cracks and leaks before buying.
