They typically consist of the following components:
- Air intake: The oxygen concentrator pulls in ambient air through an intake filter.
- Compressor: The compressor pressurizes the incoming air, preparing it for further processing.
- Sieve beds: Oxygen concentrators use specialized sieve beds made of a material called zeolite to separate nitrogen and other gases from the air. The sieve beds have the ability to adsorb nitrogen, allowing the oxygen to pass through and be collected.
- Oxygen flow control: Oxygen concentrators have controls to adjust the flow rate of oxygen being delivered to the user. This allows healthcare professionals to set the appropriate oxygen levels based on the individual’s needs.
- Oxygen delivery: The oxygen is delivered to the user through a nasal cannula or a mask, allowing them to breathe in the concentrated oxygen.
- Monitoring and safety features: Oxygen concentrators often include built-in safety features such as alarms for low oxygen levels, power failure, or blockage in the system. They may also have monitoring capabilities to track oxygen concentration and usage.
