Как работает портативный концентратор кислорода?

Чтобы fully appreciate the benefits of portable oxygen concentrators, it's important to understand their operation. The core technology is based on pressure swing adsorption (PSA). Here's a step-by-step breakdown:

1. Air Intake: The device draws in ambient air through an intake filter, which removes dust and particles.
2. Compression: A compressor pressurizes the air and sends it to a sieve bed containing a material called zeolite, which has a high affinity for nitrogen molecules.
3. Adsorption: Under pressure, the zeolite adsorbs nitrogen from the air, allowing oxygen and other gases to pass through. This process enriches the oxygen content to typically 90-95% purity.
4. Delivery: The concentrated oxygen is delivered to the user via a nasal cannula or mask. The device may offer continuous flow or pulse dose delivery, depending on the model and user's needs.
5. Exhaust: The nitrogen and other gases are vented back into the atmosphere, and the cycle repeats continuously.

This process is highly efficient and does not require chemicals or external oxygen sources. Modern concentrators use advanced electronics to monitor and adjust flow rates, ensuring optimal performance. Some models even feature smart technology, such as Bluetooth connectivity for tracking usage and health data via smartphone apps.
