What Are Oxygen Cylinders?

Oxygen cylinders are a necessity for people who are prescribed supplemental oxygen. These come in various sizes, types and capacities to meet varying requirements of different users. HPFY brings to you o2 cylinders that come in a durable design and serves you for long. Homefill cylinders are types of cylinders that allow patients to fill in oxygen using O2 concentrators. Smaller oxygen cylinders allow users to travel as they can be carried anywhere. So now, people who require continuous supply can step out of home or hospital setting.

Types of Oxygen Cylinders

Compressed Oxygen Tanks

These are the most commonly used oxygen tanks but are popular because they are inexpensive and often covered by medical insurance. Compressed oxygen cylinders are heavy and they may have issues if not kept in upright position. For portability small tanks can be filled with the big one.

Liquid Oxygen Tanks

These tanks can store a greater amount of oxygen than the compressed oxygen tanks and weigh less. These are more expensive than the compressed oxygen tanks and you cannot take them in a flight. Also, these liquid O2 cylinders have a small shelf life as otherwise the oxygen will evaporate. Portable small tanks can be filled with the large ones.

What Are The Different Sizes Of Oxygen Cylinder?

Cylinder Size	Capacity (L)	Weight (Lbs.)	Height (In.)	Diameter (In.)
M2	42	0.7	5.7	2.5

*The illustration displays Invacare HomeFill CGA870 Post Valve Cylinder and Invacare HomeFill Oxygen Compressor*

• Pull the outer ring of the connector fillport while pushing DOWN on the cylinder assembly to couple the cylinder fillport into the connector fillport
  Note: A"click" is heard when the cylinder is properly connected to the compressor
• Press the compressor power switch to the ON position
• After the cylinder is full, turn off the compressor power switch
• Grasp the cylinder assembly with one hand and with the other hand, grasp the outer ring (sleeve) of the connector fillport and push DOWN
• Lift up on the cylinder assembly to remove from the connector fillport
• When the cylinder fillport is disconnected from the connector fillport, release the outer ring (sleeve) of the connector fillport
• Remove the cylinder from the compressor cradle
• Place the fillport covers back on the cylinder and the compressor
• Install a compatible conserver or regulator
• Open the toggle valve by turning counterclockwise and examine the conserver or regulator gauge to ensure cylinder is full (needle pointing into GREEN area).
  If the cylinder is not full, perform the following:
  
  • Re-fill of the Cylinder
  • If cylinder is not full after second attempt to fill, contact the provider

Which O2 Therapy Supplies Are Used With An Oxygen Tank?

• Oxygen Compressor – Oxygen compressors are used to fill compressed oxygen from concentrator to Home Fill oxygen cylinders.
• Oxygen Concentrators - Oxygen Concentrators are used in synergy with compressors to fill oxygen tanks. These are widely used by people who carry small portable oxygen cylinders.
• Regulators/Conserving Devices - Oxygen Conserving Devices and Regulators are used to keep a check on oxygen levels inside the tank. They are also used to control the outflow of oxygen.
• Pulse Oximeters – Pulse Oximeters are widely used along with oxygen therapy supplies to help caregivers monitor SpO2 levels in the patient’s blood. These are necessary to ensure they do not receive more than required O2 levels as it can be harmful to the lungs.
• Oxygen Cannula & Mask – Oxygen cannulas and masks are used with oxygen tanks to deliver oxygen to the user.
• Carry Bags - Carry bags are frequently used by people who are prescribed oxygen and need to travel frequently. This allows them to carry cylinders anywhere with ease.
• Racks and Stands - Oxygen cylinder racks are used at homes and medical facilities to store oxygen tanks when not in use. These are useful especially to keep oxygen tanks in an upright position, making sure cylinders don't roll around.

Oxygen Tanks - Frequently Asked Questions

How do I safely use an oxygen tank?

• Don’t let anyone smoke or in the room if a patient is using oxygen.
• Always keep the tank your patient is using in the stand. Lay any other tanks on their sides and secure them so they don’t roll around
• If the valve post breaks off a tank, the pressure can release and propel the oxygen tank forward quickly.
• Keep the tank away from all heat sources like radiators, heat ducts, stoves, fireplaces, matches, and lighters Oxygen is flammable, i.e., it can catch fire instantly and make things burn or even explode.

How do I attach the regulator to the tank?

1. Remove the plastic wrap from the valve post on the tank. It may contain a washer.
2. Attach the regulator to the tank by slipping the regulator over the tank’s valve post. Align the pegs on the inside of the regulator yoke with the holes in the valve post. Slide the regulator forward so the pegs go into the holes.
3. Fasten the regulator to the tank by turning the T-handle on the regulator until it is tight. If the handle is not tight enough or the washer is not in place, the tank will leak when the valve opens.
