What is Oxygen Concentrator?
An oxygen concentrator is a medical device that helps in providing additional oxygen to those with respiratory conditions or those who need more oxygen in their bloodstream. It is frequently applied to both home healthcare and medical facilities like hospitals and clinics.
An oxygen concentrator's primary function is to extract and concentrate the ambient air, which normally includes around 21% oxygen, so that it can be given to the patient at greater concentrations. This is carried out by the device using a technique known as pressure swing adsorption (PSA) or membrane separation.
Overview / Product Profile of Oxygen Concentrator:
An oxygen concentrator machine consists of several key components that work together to extract, concentrate, and deliver oxygen to individuals in need.
These components include:
1) Compressor: The role of the compressor is to pull in atmospheric air and compressing it to a higher pressure. This compressed air serves as the input for the oxygen concentration process.
2) Filters: To get rid of dust, pollutants, and other particles, the incoming air is put through a number of filters. With the help of these filters, the patient will receive clean, contaminant-free oxygen.
3) Sieve Beds or Membranes: To separate oxygen from nitrogen and other gases, oxygen concentrators either utilise sieve beds filled with zeolite material or specialised membranes. The oxygen molecules can be specifically adsorbed or separated from the other gases by the compressed air being channelled through these beds or membranes.
4) Flow metre: The flow metre controls and monitors the oxygen flow rate to the patient. It enables medical professionals to modify oxygen flow in accordance with the patient's prescribed therapy.
5) Oxygen Storage: Before the concentrated oxygen is given to the patient, it is collected and stored by the oxygen concentrator. Even when demand fluctuates, a constant supply of oxygen is ensured by this storage mechanism.
6) Oxygen Delivery System: The patient receives oxygen using a nasal cannula, an oxygen mask, or various oxygen delivery systems. These devices make sure the patient gets the right amount of oxygen and can change the delivery technique depending on what the patient needs.
7) Control Panel: The oxygen concentrator's control panel, also known as the user interface, enables users to change parameters including oxygen flow rate, power on/off, and alarms. It offers a user-friendly interface for patients and healthcare professionals to check and manage the device's operation.
These components work together to extract oxygen from the surrounding air, concentrate it to higher levels, store it, and deliver it to patients who require supplemental oxygen.

History of Oxygen Concentrator:
The invention of portable, reliable oxygen therapy equipment began in the 1970s, which is when oxygen concentrator units first appeared on the scene. Prior to that, liquid oxygen systems or large, heavy oxygen cylinders were the main methods of oxygen therapy delivery, which had an impact on mobility and convenience.
The creation of oxygen concentrators was intended to get over these restrictions and offer supplemental oxygen users a more workable solution. The first oxygen concentrator models were big, stationary devices that were mostly seen in hospitals and healthcare centres.
Dr. Robert D. Shaw, an American engineer, obtained a patent for the first useful home oxygen concentrator in 1976. By allowing patients to get oxygen therapy in the convenience of their own homes, his invention represented a significant improvement in the field of oxygen therapy. The apparatus, dubbed the "Shaw Box," used the pressure swing adsorption (PSA) method to draw out and concentrate oxygen from the surrounding air.
Oxygen concentrators received more advancements in the late 1990s and early 2000s with the addition of digital controls, greater safety measures, and improved power economy. These improvements improved their dependability, made them simpler to use, and allowed them to supply precise oxygen concentrations based on the needs of each patient.
Portable oxygen concentrators (POCs), which have become more common as a result of technological and miniaturisation advancements, are becoming more common. Patients can obtain oxygen therapy on the go with the help of these portable, lightweight devices, which also make it easier for them to travel and carry out daily tasks. POCs often use pulse dosage delivery, which means that oxygen is given to patients in brief bursts in response to their inhalations. This technique helps to preserve oxygen and prolong battery life.
In the recent years, Oxygen therapy has undergone a profound change as a result of the invention and advancement of oxygen concentrators. By giving people who are suffering from COVID-19 and other respiratory diseases a dependable and practical supply of supplemental oxygen, they have improved their quality of life.
Frequently Asked Questions (FAQs)
How does an oxygen concentrator work?
An oxygen concentrator works by taking in ambient air, filtering out nitrogen and other gases, and delivering concentrated oxygen to the user. This is achieved through a process called pressure swing adsorption, where air is passed through molecular sieves that selectively adsorb nitrogen, allowing oxygen to pass through and be collected for use.
