How do I choose the right oxygen equipment for me? Show
You, your health care provider and your oxygen supplier should all work together to choose the oxygen system that is right for you — one that takes into account your lifestyle and activities, as well as the amount of oxygen you need. The goal is to have oxygen equipment that you can and will wear, so you can keep enjoying your usual activities. Some of the factors to consider when choosing your system and equipment are listed below:
What type of equipment is available? The three types of oxygen systems currently available are:
The compressed gas system consists of a stationary concentrator, to be used in the home, and a small oxygen tank, to be used outside the home. The liquid oxygen system consists of a stationary concentrator or reservoir to use while you are in your home and an ambulatory tank to use when you go out. The portable oxygen concentrator can serve as both the ambulatory device and the stationary concentrator in certain circumstances.
Ambulatory Versus Portable Oxygen EquipmentWhile the terms portable and ambulatory oxygen equipment are often used interchangeably, there is an important difference. In 1999, the 5th Oxygen Consensus Conference differentiated between portable and ambulatory oxygen systems. Portables are defined as easily moved devices that are not designed to be carried and weigh more than 10 pounds. Ambulatory devices are defined as weighing less than 10 pounds, available for daily use, designed to be carried by the patient, and lasting four to six hours at a setting of 2 liters per minute. They are normally small aluminum cylinders or liquid oxygen containers equipped with oxygen conserving devices (OCDs). E tanks are the larger, older metal tanks that are wheeled around. They can be the right choice for some people and situations, but are generally not considered to be ambulatory devices. They are often used as back-up systems in the home, should the electric power in the home fail. Oxygen Conserving Device (OCD)The oxygen conserving device (OCD) is the device on your small compressed gas tank that makes the oxygen supply last longer. It causes the oxygen to be delivered only when you take a breath. Not all OCDs deliver the same amount of oxygen as a continuous flow would, so it is important that your oxygen saturation be tested at rest and with activity while you are using the OCD, to make sure you are getting enough oxygen. AccessoriesSeveral accessories come with your oxygen equipment. In addition, there are other accessories to make wearing or carrying your oxygen more comfortable. Below are examples of a few basic accessories.
Higher Oxygen FlowsRates of 4 liters/minute or greater are considered higher oxygen flow.
Where do I get my oxygen and equipment? Your provider can help you choose an oxygen company, or you may choose any company you want. Some insurance policies dictate which oxygen company you must use. Who will pay for my oxygen and equipment? Most insurance policies cover supplemental oxygen when the medical necessity for oxygen is demonstrated. This necessity is based on the oxygen saturation or the arterial blood gas measurements. Generally, if your O2 saturation falls below 89 percent, or your paO2 falls below 60 mm Hg — whether at rest, with activity or during sleep — then you qualify for supplemental oxygen. For more information, see The Need for Supplemental Oxygen. How do I maintain my equipment? Your oxygen supply company will give you instructions for cleaning your equipment. Some basics are listed below:

Which of the following is the best advice to deliver high concentration oxygen to a breathing?For breathless patients requiring high concentration oxygen, a well fitted non-rebreathing reservoir mask will increase the amount of oxygen available during inspiration. Emergency oxygen treatment is best given by face masks.
What is the preferred oxygen delivery device?A nasal cannula is the most common oxygen delivery system, used for mild hypoxia (figure 4a). It delivers oxygen into the nasopharyngeal space and can be set to deliver between 1 and 6 L·min−1 (24–40% FIO2) (table 2).
What oxygen delivery device can provide precise concentrations of oxygen?An air/oxygen blender can provide precise oxygen delivery independent of the patient's inspiratory flow demands.
Which method of supplemental oxygen provides the highest concentrations of oxygen?An air-entrainment (also known as venturi) mask can provide a pre-set oxygen to the patient using jet mixing. As the percent of inspired oxygen increases using such a mask, the air-to-oxygen ratio decreases, causing the maximum concentration of oxygen provided by an air-entrainment mask to be around 40%.
