In the following paragraphs we will walk you through some of the top mobile oxygen machines you can get your hands on.
1. GVS Oxygen 5L Oxy-Pure Ultra Silence Oxygen Concentrator
The GVS 5-liter Oxy-Pure is an ultra-silent electrically-powered oxygen concentrator. It has a flow rate of 0.5 to 5 litres per minute and an oxygen concentration of 93% (±3%). Noise level is ≤ 43 DBA which is quite low, and therefore, comfortable for the patient. Outlet pressure is 0.04-0.07 mpa.
The GVS Oxy-Pure is designed to be used in hospitals, nursing homes, clinics and homes. It extracts oxygen from the atmosphere by a process known as Pressure Swing Adsorption (PSA). Air contains approximately 78% nitrogen, 20% oxygen and small amounts of other gases. PSA is a technique that separates nitrogen from the air, leaving out air that is mostly oxygen. For this a molecular sieve made of artificial zeolite is used. Atmospheric air is passed through this sieve/filter where zeolite adsorbs nitrogen, keeping it trapped in the filter, while the rest of the gases move out. This filtered air is predominantly oxygen with a purity level of nearly 93%, and it is used for medical treatment.
The Oxy-Pure has a humidifier that adds moisture to the outflowing air which tends to be a bit dry. This prevents irritation in the throat and nasal passages.
The machine has buttons for turning on/off the power and adjusting the time. It has an LCD display that shows vital information like Switch Times, Operating Pressure (in mpa), Operating Time and Accumulated Running Time. A light indicator and an audible alarm alert the user in case of low or high pressure. If the pressure is too low, the light turns yellow; if it is too high, it turns red. In both cases, the alarm goes off. When connected to the power source, the light becomes green. In case of power outage, or a mechanical failure like a damaged fuse, the light turns red and the alarm is sounded.

How does an Oxygen Concentrator works?
An oxygen concentrator is a medical device that produces air rich in oxygen. It takes in ambient air and removed nitrogen from it to produce a stream of air that’s mostly oxygen. Air is made up of 78% nitrogen and 21% oxygen, with trace amounts of argon, carbon dioxide, ozone and other gases. An oxygen concentrator filters air by taking out nitrogen to provide an air supply containing 90-95% oxygen.
Oxygen concentrators are widely used in the healthcare sector. They are required for patients who have difficulty breathing normally, or have low oxygen in their blood. Oxygen concentrators do not use a readymade source of compressed oxygen like an oxygen tank. Rather, they take in air, change its concentration, and give out oxygen-enriched air.
The Science behind Oxygen Concentration
An oxygen concentrator runs on electric power, either through a wall socket or a battery. If it relies on a battery, the battery needs to be plugged in to a wall socket to ensure an undisrupted power supply. Since it is a medical gadget, an oxygen machine needs a prescription, and cannot be bought over the counter.
Now let us understand the science behind oxygen concentration, and what really happens inside a concentrator. As mentioned already, an oxygen concentrator is a device that filters ambient air to generate air with a high concentration of oxygen. This is achieved by drawing in air through a motor, compressing it, and passing it through a molecular sieve bed filter.
An oxygen concentrator typically contains, among other things, a motor/compressor, a heat exchanger, two cylinders containing zeolite sieve beds, a product tank, a pressure regulator and a few valves for regulating airflow. First, the motor/compressor compresses the inflowing air and feeds it to the filter. The filter then removes nitrogen by a process called Pressure Swing Adsorption (PSA).
PSA is a technique used in separation of a gas from a mixture of gases under pressure. The filters use a mineral named zeolite for adsorption of nitrogen. Zeolite has a large surface area, and is made up of millions and millions of porous microscopic cubes. The mineral only eliminated nitrogen, allowing the rest of the atmospheric gases to pass through untouched.
When air passes through the filter beds at high pressure, zeolite adsorbs huge amounts of nitrogen due to its unique chemical nature and enhanced surface area. As a result, the outgoing air has a high concentration of oxygen. There are two stages to oxygen concentration. Air from the compressor first enters cylinder 1. A four-way selenoid valve regulates this part of the airflow.
The pressure inside the 1st cylinder is around 2.5 times that of normal atmospheric pressure. It facilitates rapid adsorption of nitrogen which leaves behind pure oxygen mixed with traces of other gases. This is the first stage of the concentration process and it takes about three seconds.
At the end of this stage, the oxygen-enriched air is channelized into the pressure-equalizing reservoir, also called product tank, and the incoming compressed air is directed towards cylinder 2 instead of 1.
As a result, pressure inside cylinder 1 drops which allows for desorption of nitrogen back into gas. In the second stage, there is another change in valve position, and the nitrogen-filled air from the 1st cylinder is released back into the atmosphere through a vent.
At the same time, oxygen-rich air leaves the reservoir and exits the machine though a flowmeter. The purified air is finally supplied to patients with the help of hoses, nasal masks and cannulas.
The pressure inside the hose is maintained by a pressure-regulating valve. A cooling system is also put in place to prevent the oxygen concentrator from overheating. This, in a nutshell, is how oxygen concentrators work. Oxygen machines can be of two types: fixed and portable.
Fixed oxygen machines need a wall socket, and hence, are not mobile. Portable devices can, however, be carried around, and are surprisingly easy to use. Let us now find out more about portable oxygen concentrators, how they work, and their uses.
Portable Oxygen Concentrators
A portable oxygen concentrator is an affordable source of on-the-go oxygen. It is a convenient alternative to cryogenic oxygen tanks that depend on a limited supply of compressed oxygen. A portable oxygen device typically has two settings: pulse dose and continuous flow. Pulse dose mode is suitable for daytime use. It delivers air through a cannula.
Machines with pulse dose mode are more compact and battery-efficient. Continuous mode is best suited for use during sleep. It supplies air through a tube and ensures a constant flow of air throughout the night. Portable oxygen machines are lightweight and easy to transport. They are permitted on public transport like trains, buses and ships.
Most devices are also approved by the United States Federal Aviation Administration (FAA) and can be carried onboard commercial aircrafts. However, users need to check with the airline they’re flying with if the brand and model of their oxygen concentrator is allowed on their flights.
In aircrafts without a pressurized cabin, a special kind of oxygen concentrator is needed which can deliver enough flowrate even at high altitudes. A portable oxygen concentrator is super flexible and can adapt to different modes of power supply. It can operate on a fixed power supply from a wall socket, be plugged into a car 12V D/C cigarette lighter, or be powered by a lithium ion battery.
Both fixed and portable machines have alarms to alert the user about power failure and sudden rise or fall in pressure. This helps them attend to the issue immediately and fix it at the earliest. In a portable machine, as in a fixed one, the purified air is delivered to the patient through a tube with either a cannula or mask fitted at its end. A cannula is a thin tube with two outlets that fits under the nose.
The patient breathes in the oxygen through the two vents that remain slightly inserted into the nostrils. The tube may be supported by loops around the ears and neck. While breathing through a cannula, a patient also breathes in the surrounding air as the nostrils are not fully covered.
In a mask, the area around the mouth and nose are fully covered and this helps provide a more concentrated supply of medical-grade oxygen. For travel purposes, of course, a cannula is more practical and comfortable to wear. It is easier to use and carry in the subway and streets than a full mask.
Portable oxygen concentrators produce anywhere between 1-5 liters of oxygen every minute. They ensure a continuous supply of oxygen as they use ambient air to produce oxygen-enriched air. They are great for mobile medical facilities like ambulances and mobile hospitals used in disaster relief.
An oxygen concentrator is a life-supporting gadget. It is a quick, effective and cost-efficient source of pure oxygen. It is used in hospitals, ambulances and homes to treat patients who need a constant supply of oxygen. Portable oxygen concentrators provide the same convenience of an oxygen concentrator but with the additional ease of transportability. They are travel-size, easy-to-handle and tailored for mobility. No matter where you are, you can rely on a portable oxygen concentrator to provide you an unlimited, and possibly uninterrupted, supply of pure oxygen.
