5L Oxygen Concentrator

5L Oxygen Concentrator

An oxygen concentrator is a medical device that extracts oxygen from the ambient air, filters out nitrogen and other gases, and delivers it to a user who needs supplemental oxygen for a medical condition. It creates its own oxygen on demand, unlike a compressed or liquid oxygen tank which holds a finite supply. These devices are powered by electricity or batteries and are used for conditions like COPD, cystic fibrosis, and sleep apnea to improve breathing and stamina.

How it works:

1. Intake:

The concentrator takes in ambient air, which is about 79% nitrogen and 21% oxygen. 

2. Filtration:

The air passes through a series of filters and sieve materials (such as zeolite canisters) that separate and remove the nitrogen. 

3. Oxygen Production:

This process leaves behind purified, medical-grade oxygen. 

4. Delivery:

The oxygen is then compressed and sent to the user through a nasal cannula or mask. 

Types of oxygen concentrators:

Stationary/Home models:

These are larger, heavier units that provide continuous flow oxygen and are typically plugged into a wall socket. 

Portable oxygen concentrators (POCs):

Lighter and smaller than stationary units, POCs can be powered by rechargeable batteries, home electricity (AC), or a car's cigarette lighter socket (DC). 

Key differences from oxygen tanks:

On-demand oxygen: Concentrators make oxygen as needed, while tanks store a limited supply that can run out. 

Power source: Concentrators require electricity or battery power to operate. 

Safety: Concentrators are a safer option than carrying heavy, pressurized tanks. 

Important considerations:

Prescription required:

An oxygen concentrator should only be used under the guidance of a doctor, as using one without a prescription can be dangerous. 

Settings:

Some models can deliver oxygen continuously, while others offer pulse-dose delivery, which releases oxygen in bursts during inhalation. 

Noise:

Oxygen concentrators can be noisy due to their internal mechanisms, though newer models aim to reduce this sound.
