Frequently Asked Questions About Oxygen Concentrators

Q1: What is an oxygen concentrator?

An oxygen concentrator is a medical device designed to deliver supplemental oxygen to individuals who have low blood oxygen levels due to respiratory or cardiovascular conditions. It works by filtering ambient air—removing nitrogen and other gases—and concentrating the oxygen content to provide a continuous flow of purified oxygen at a prescribed concentration, typically between 90% and 95% purity.

Unlike oxygen tanks that store compressed gas, concentrators generate oxygen on demand, making them a safer, more sustainable, and cost-effective long-term solution for patients requiring oxygen therapy at home or on the go.

Q2: How does an oxygen concentrator work?

Oxygen concentrators operate through a process called Pressure Swing Adsorption (PSA), which involves several key stages:

1. Air Intake: The device draws in surrounding air through an intake filter.
2. Compression: The air is compressed to increase pressure, preparing it for separation.
3. Nitrogen Absorption: The compressed air passes through chambers filled with zeolite molecular sieves, which selectively adsorb nitrogen molecules, allowing oxygen and other trace gases to pass through.
4. Oxygen Delivery: The concentrated oxygen is then delivered to the patient via a nasal cannula or mask at a controlled flow rate (measured in liters per minute).
5. Exhaust Cycle: Periodically, the system releases the trapped nitrogen back into the atmosphere to regenerate the sieve beds for the next cycle.

This continuous cycle ensures a steady supply of medical-grade oxygen without the need for refilling or replacing gas cylinders.

Q3: What are the benefits of using an oxygen concentrator?

Oxygen concentrators offer numerous advantages for patients requiring long-term oxygen therapy:

• Continuous Oxygen Supply: Provides a reliable, uninterrupted source of oxygen without the limitations of tank capacity.
