In medical and industrial concerns, the supply and demand for oxygen cylinders are high. The importance of these is underscored because certain conditions require the use of oxygen therapy as a treatment. The pressure and volume distribution of oxygen in these cylinders differ with the various types of oxygen cylinders.
Oxygen cylinders come in the following types based on their size:
Small portable oxygen cylinders
Small portable oxygen cylinders enhance mobility and convenience and cater to patients who often move around, even temporarily. This is ideal for short-term use. They store fewer oxygen concentrations than larger cylinders; hence, they are suitable for patients who need on-demand oxygen.
Large oxygen cylinders
Large oxygen cylinders are stationary and are mostly used in hospitals or other health institutions. They are heavy, often containing a higher flow rate and more oxygen. Large cylinders are often used in procedures where patients need constant oxygen concentration or in areas with higher volume requirements for oxygen therapy.
According to their shapes, there are two types of oxygen cylinders:
Cylinder D
Cylinder D is often used by medical offices and hospitals. These establishments need a high flow of oxygen and require an ample supply stored in a large cylinder like the D. Its dimension is 26 by 9 inches and weighs 120 ounces when full. It has a water capacity of 103 ounces and carries up to 1,875 psi of pressure.
Cylinder E
Cylinder E is smaller than the D which makes it easier to carry around. It is also commonly used in medical institutions and homes where oxygen therapy is required. Its dimension is 19 by 8 inches and weighs 80 ounces when full. It has a water capacity of 48 ounces and carries up to 2,200 psi of pressure.
Oxygen cylinders can also be categorized as:
Steel
Steel oxygen cylinders are strong and long-lasting. They carry heavy pressures of up to 2,200 psi. However, they are also heavier than other materials used to make oxygen cylinders.
Aluminum
Aluminum oxygen cylinders weigh less but are not as strong. They carry lower pressures than steel and are often used for low-flow applications.
CFRP composite cylinders
CFRP composite oxygen cylinders are lightweight but also very strong. They are made from reinforced plastic that has carbon fiber and a polymer composite. They carry high pressures but weigh less than metal cylinders. They also have a long life and can resist corrosion.
The size of an oxygen cylinder also differs by the industry in which it is used.
Industrial oxygen cylinders
Industrial oxygen cylinders are mostly larger than medical ones. While medical oxygen tanks carry up to 2,200 psi of pressure, industrial tanks can carry up to 3,000 psi. The industrial tanks are also likely to be made of steel or aluminum, where the former is thicker and stronger and the latter is lighter and more prone to bursting.
Medical oxygen cylinders
Medical oxygen cylinders are lighter and easier to carry. The most common sizes are C, D, and E, with the C cylinder being the smallest and least used and the E cylinder being more popular among homes and medical offices.
Using an oxygen tank as an accent piece in a room or workshop can be a cool and creative idea. An artist can create a piece that captures the spirit of fighting for one's life, metalwork, vintage art, or even just a romantic notion of the ruins. It can also serve practically as a lamp, a planter, or a stool. Below are some cute ways an oxygen tank can be decorated and transformed into creative art:
Using paint
Using paint, one can turn a tank into a work of art by painting bold stripes, patterns, or illustrations. This could make it a pop of color or even turn it into a themed piece, so choosing a color scheme that harmonizes with the space is important.
Stencils and stickers
Stencils and stickers are good decoration ideas for oxygen tanks. This is because one can easily apply designs that range from flowers to quotes or geometric shapes. They can be easily changed if one wants to change the decor frequently.
Fabric wraps
A fabric wrap like a cloth, yarn, or decorative ribbon giving the oxygen tank a completely different look. It can then be matched to the general theme of the room or the taste of the person using the room.
Wall mounts
Mounting the oxygen tank on the wall will turn it from a simple piece of decor into a striking piece of wall art. It can be hung as a simple backdrop or integrated into a more complex arrangement with other items, such as shelves and photos or other pieces of artwork.
The following factors should be considered when choosing an oxygen cylinder:
Material
Oxygen cylinders are mostly made from steel, aluminum, and carbon fiber. While steel cylinders are the strongest, they are also the heaviest. China aluminum cylinders are lighter but not as strong. Carbon fiber cylinders combine the best of both by being strong but also very light. The material used to make a cylinder also affects how much oxygen it can carry and how easy it is to carry.
Size and capacity
Several factors determine the appropriate size and capacity of an oxygen cylinder, such as the usage time and space availability. Larger cylinders provide more oxygen and are better used in stationary settings like hospitals. Portable oxygen concentrators are smaller and easier to move with. These are more convenient for home use or when a person who needs medical oxygen is traveling.
Pressure rating
All oxygen cylinders are labeled with the maximum pressure they can carry. This is important for the safety of the user. The pressure also affects how much oxygen the tank can carry. Higher pressure cylinders can carry more oxygen because they can contain more concentration. For industrial uses, choose high-pressure cylinders; for home use, low-pressure ones are sufficient.
Regulator compatibility
One should ensure the right regulator is compatible with the cylinder when using an oxygen cylinder. The regulator helps control how fast the oxygen comes out of the cylinder. If the oxygen is coming out too fast or slow, there might be a problem. Regulators also come in different types of flowmeters, which affect how much oxygen a person gets; variable flowmeters are more adjustable, while continuous flowmeters are simpler and cheaper.
Transport needs
Transportation of oxygen cylinders must be done safely, preferably using protective caps and carrying belts. Cylinders made of lighter materials or composites are easier for caregivers and medical personnel to carry in emergencies. Security and proper storage in vehicles during transport help prevent accidents or damage.
Life support
They support the lives of people with respiratory diseases like COPD by helping them breathe. They are also used during surgeries and in emergencies to help anesthetize patients.
Industrial application
They are used widely to cut metals, weld them, and even purify them by taking away other gases. They also make metalwork and glass sharper and cleaner when applying heat with an oxygen-acetylene flame, which is vital in places that do industrial work.
Emergency and disaster use
They are critical during fires to replace smoke-filled air. People who dive use them to avoid accidents like the bends. They are also used in remote areas where other power sources are limited, making them helpful in emergencies or when there is trouble with power failure. Lastly, they are great for knowing the oxygen levels in areas with forests and among people who tend sheep and cattle because they help measure oxygen levels in the air and are good for monitoring environmental changes.
Portable power
They can be used to run oxygen tools and machines that work with gas, big lanterns, and even some kinds of boats, which is good for people who camp or go far from home. They're a good backup power source when away from home or in places without electricity.
The cost of an oxygen concentrator depends on the type of concentrator it is and how much oxygen it can give. The more the oxygen, the more expensive it will be. An o2 cylinder can be rented, but renting means paying a small amount, which, over time, may become the same as buying one. Buying an oxygen tank, flow regulators, and tubing are all additional expenses. Buying an average stationary oxygen concentrator can be anywhere more than $500. Portable ones are cheaper, around $300, but larger stationary models are more expensive, around $1,500.
Some dangers can arise from mishandling medical or industrial oxygen cylinders. The oxygen inside can explode and hurt people if the tank gets too hot or the pressure inside becomes too high. It can also react dangerously with other chemicals and cause a fire if sparks are near them. Old or broken tubes connected to the cylinder can let out too much or too little oxygen, which is dangerous. People can get hurt lifting the heavy cylinders the wrong way or leaving them where they fall over. Losing the key to the oxygen lock cabinet for storage or leaving the key within reach of children can tempt them to try and play with it, which is dangerous.
Manufacturers and caregivers do several checks on medical oxygen tanks every so often. They also do more checks on the ones open to people so the companies can replace them before they explode or get too old. They usually change them after six or seven years, but some tanks can last longer. Those not often checked can still be used for many years, around 20 or more, but they won't always work properly or be as safe. How much the cylinder is used and what kind of shape it is in will also affect how long the cylinder will last.
