For those suffering from severe pneumonia and other respiratory disorders, such as COVID-19, oxygen is a life-saving therapeutic medicinal gas. Many COVID-19 patients require immediate oxygen assistance to live.
While oxygen cylinders are in short supply, oxygen concentrators are among the most sought-after technologies for oxygen therapy in home isolation.
It is important to remember, however, that the device should only be used by persons who have minor COVID-19 symptoms. The device is not suitable for individuals with oxygen saturation levels less than 85% or those with severe COVID-19. Such patients should seek medical attention as soon as possible. This is due to the fact that concentrators can only provide 5 to 10 litres of oxygen per minute. As a result, they are inappropriate for critical patients requiring 40 to 45 litres of pure oxygen per minute.
An oxygen concentrator is a type of oxygen administration equipment that is used to treat a number of respiratory conditions such as COPD, cystic fibrosis and mild COVID-19 symptoms.
Oxygen concentrators are like oxygen cylinders that supply medical-grade oxygen that is inhaled through a nasal cannula or oxygen mask.
However, a concentrator, unlike oxygen cylinders, does not need to be refilled and may give oxygen 24 hours a day. A typical oxygen concentrator can produce pure oxygen at a rate of 5 to 10 litres per minute (LPM).
The main distinction between oxygen concentrators and oxygen cylinders are that oxygen concentrators do not contain compressed oxygen or any other liquid. Thus , oxygen concentrators don't have nearly as many of the safety concerns as compressed oxygen does. They're also a lot easier to use and less expensive, so they're a common long-term therapy choice for a range of lung disorders.
The device consists of a compressor oxygen tank, sieve bed filter, pressure valve, and a nasal cannula (or oxygen mask).
An oxygen concentrator takes in fresh air, filters it, and then distributes it. Prior to entering the concentrator, air is composed of 80% nitrogen and 20% oxygen. When air is passed via an oxygen concentrator, it includes 90-95 percent pure oxygen and 5-10% nitrogen. The nitrogen is separated to provide the patient with the maximum dose of oxygen possible, as obtaining that proportion of oxygen without the assistance of a medical instrument is difficult.
The concentrator's major components are the compressor and the sieve bed filter. The compressor compresses the filtered air before sending it in a continuous stream to the concentrator.
The pressurised air is then sent to the sieve bed filters. The sieve bed filter is essential since it is the device that eliminates nitrogen from the air. The sieve bed contains a substance called Zeolite, which is a six-sided tiny cube with holes on each side and is responsible for removing nitrogen from the air.
In the concentrator, there are two sieve beds. Air is driven into the first filter bed after it has been compressed in the concentrator. Oxygen is introduced into the product tank. The first sieve bed is then filled with nitrogen. The compressed air is then transported to the second sieve bed once the gas flow is switched. The first sieve bed's compressor is moved to the outside room, and the air from the product tank is returned to the first sieve bed.
The Zeolite releases nitrogen due to the reduction in pressure from the first sieve layer and the weakening of oxygen. The Oxygen and Nitrogen recombine and are released back into the room as ordinary air. The compressed air is then transferred to the second sieve, where oxygen is carried through it to the Product Tank. After a few seconds, the cycle begins again with the first sieve.
Other critical components are the cooling system, which prevents the portable oxygen concentrator from overheating, and the nasal cannula, which provides the filtered oxygen once it has passed through all of the sieve bed filters. The cannula aids in oxygen absorption.
Oxygen concentrators are classified into two types:
Continuous flow: Regardless of whether the patient is inhaling the oxygen or not, this sort of concentrator provides the same flow of oxygen every minute unless it is switched off.
Continuous flow is similar to what an oxygen tank or liquid oxygen tank would provide.
Pulse dose: These concentrators are rather smart in that they can detect the patient's breathing pattern and release oxygen when inhalation is detected. The amount of oxygen delivered per minute by pulse dose concentrators varies.
Pulse flow concentrators are nearly usually smaller and lighter than their continuous flow equivalents, which is one of their main advantages.
Only mild to moderately unwell individuals with oxygen saturation levels ranging from 90% to 94 percent, should utilise an oxygen concentrator under medical supervision. Patients with oxygen saturation levels as low as 85% can also utilise oxygen concentrators in an emergency or until they are admitted to the hospital. However, such individuals should be switched to a cylinder with a greater oxygen flow and brought to a hospital as soon as possible. The device is not recommended for ICU patients.
Oxygen concentrators are the ideal alternative for cylinders and liquid medical oxygen, both of which are difficult to store and carry.
Concentrators are a one-time purchase. Concentrators are more expensive than cylinders, although they are a one-time investment with low ongoing costs.
Concentrators don’t require refilling. Concentrators, unlike cylinders, do not need to be refilled and can produce oxygen 24 hours a day using just ambient air and electricity.
However, Concentrators are ineffective for critically ill patients who need 40 to 45 litres of pure oxygen per minute.
Some of the acute and chronic disorders listed below can benefit from oxygen concentrators.
Acute Conditions that need the use of an oxygen concentrator
Acute conditions that would need the use of an oxygen concentrator for short-term oxygen treatment include:
Asthma: This is a disorder in which your airways get inflamed and produce a lot of mucus, making breathing difficult. While there are a variety of medications that may be used to treat and manage asthma, an oxygen concentrator can deliver high quantities of oxygen to the patient's bloodstream, if they are suffering from or have previously suffered from an asthma attack
Pneumonia: Pneumonia is an illness in which one or both of your lungs' air sacs become inflamed and, in many cases, fill up with fluid. Many pneumonia patients have been administered oxygen treatment, and their clinical results have been positive.
Respiratory distress syndrome (RDS): RDS is a respiratory condition that usually affects babies, especially those delivered six weeks or more before their due date. RDS causes neonates to generate inadequate surfactant (a substance that coats the lungs), causing their lungs to collapse and making breathing difficult. Oxygen treatment, which involves the use of oxygen concentrators, helps to pump oxygen into the newborns' bloodstream and lungs, reducing the risk of future difficulties.
Bronchopulmonary dysplasia (BPD): RDS-affected newborns are at an increased risk of developing BPD. This is a serious lung ailment that need long-term breathing assistance.
After the surgery. You may require oxygen for a short length of time following surgery in some cases.
The following are some chronic diseases that necessitate the use of an oxygen concentrator on a long-term basis:
Chronic obstructive pulmonary disease (COPD): When you have COPD, your lungs suffer from chronic lung disease, making it difficult for them to absorb adequate oxygen. As a result, you may experience breathing difficulties, which oxygen treatment using a concentrator can alleviate.
Cystic fibrosis: This disease harms the digestive system and the lungs. It's an uncommon disease that affects the cells in the body that make mucus, sweat, and digestive fluids. The fluids are altered, resulting in a stickier, thicker solution that clogs the sick person's ducts, tubes, and passageways.
Sleep Apnea: Sleep apnea is a serious sleeping problem in which a person's breathing intermittently stops and starts throughout their sleep. Continuous positive airway pressure (CPAP), weight loss, and physical activity are usually used to treat this disease, while some persons with sleep apnea may require oxygen therapy.
The following are some prominent benefits of using an Oxygen Concentrator.
The drawbacks of an oxygen concentrator differ based on the model, kind, or variety.
Oxygen concentrators are available in both fixed and portable types. There are some differences between both model kinds, but the methods below will work for either device.
Here are the steps to using an oxygen concentrator:
Before purchasing an oxygen concentrator, check with a physician to determine the quantity of oxygen per litre that the patient requires. Before acquiring an oxygen concentrator, a person should consider the following factors, according to medical and industry experts:
