Portable Oxygen Concentrator - Portable Oxygen Equipment

Portable oxygen concentrators, commonly abbreviated as POCs, are relatively small medical devices that deliver concentrated oxygen to a patient. These devices function by taking ambient room air or the earth's atmosphere and filtering everything out except for oxygen. In more simplistic terms, POCs concentrate oxygen from the air around you. Depending upon a patient's respiratory needs, portable concentrators are available in two delivery methods, which satisfies the needs of people using oxygen therapy: pulse dose and continuous flow. To determine which portable oxygen concentrator will meet your specific needs, Vitality Medical suggests that you consult with your medical provider.

Pulse Dose Oxygen Machines

A pulse dose oxygen machine, also referred to as "on-demand therapy," intermittently administers a volume of oxygen measured in milliliters per breath (mL/breath). Pulse dose machines have the capability of reaching a setting of 6, which is not the same as 6 liters per minute (LPM). Most patients that require oxygen therapy during sleep do not use a pulse dose oxygen machine, as it may not detect breaths as well. However, that is not to say that it is impossible. We recommend that you confer with your medical provider about sleeping with these devices, as your practitioner will most likely have you do a sleep study to determine if it adequately delivers the necessary supplemental oxygen. An oxygen machine portable concentrator is, quite commonly, smaller than continuous flow generators; in fact, it is so small and light that most patients can easily transport one with a strap or handle. Please keep in mind, though, that pulse dose portable oxygen machines are also not compatible with CPAP or BiPAP machines; if you use either of those machines to treat sleep apnea, you will need to couple your sleep apnea device with a continuous flow portable oxygen concentrator.

Continuous Flow Portable Oxygen Concentrators

Continuous flow portable oxygen concentrators, dissimilar to pulse dose machines, administer oxygen in liters per minute (LPM). Therapeutic range, for a continuous flow machine, usually varies between 1 and 3 liters per minute. Instead of delivering therapeutic oxygen per breath, as a pulse dose model performs, these models continuously, during inhalation and exhalation, administer oxygen. Generally speaking, a continuous flow model is significantly larger in size and weight, as it requires a larger pump and assembly to provide the continuity. Because these models tend to be larger, they generally come with a cart so you can "wheel" them around your environment. In addition to a wheeled cart, many of these concentrators also come with a retractable handle. A continuous flow portable concentrator is compatible with a CPAP or BiPAP machine. To couple the two devices together, simply give one of Vitality Medical's friendly and knowledgeable representatives a call, and they will instruct you as to what you need to do to successfully couple the two machines. Putting the nuances between continuous flow and pulse dose aside, more and more individuals are turning to either POC model because they are perfect for travel.

Choosing a Travel Oxygen Concentrator

Many patients believe that their quality of life is being constrained due to the necessity of oxygen therapy. However, portable concentrators is the solution to revitalize their quality of life. In fact, with portable oxygen generators, individuals can go out to dinner at restaurants, visit friends and family, enjoy vacations, even travel on airlines! The Federal Aviation Administration, FAA, approves a wide variety of machines for use on board of commercial aircrafts. All travel oxygen concentrators, approved by the FAA, function by method of electricity, either from a battery, AC (alternating current) wall power supply, or DC (direct current) car power supply. POCs are multi-voltage, suggesting that these machines can be used anywhere in the world. Once abroad, all you need to do to resume operation is combine your oxygen machine with an international travel adapter (so that your plug will fit into the appropriate electrical socket). Please note, a power inverter should never be coupled with a portable O2 concentrator.

There are some stipulations that the FAA requires that you comply with in order to fly with your portable machine: battery time and a prescription stating a medical necessity. Battery time is a crucial component when using your oxygen therapy device on a flight. Each airline has their own regulations concerning the use of a travel oxygen concentrator during flight. To be absolutely certain of your flight's regulations, please contact the airline you are flying with and ask them their policies regarding POCs. However, as a general rule of thumb, most commercial airlines require that patients have 150% of battery life to equal the time of flight. For example, if your flight is 2 hours long, you will need, at the bare minimum, 3 hours of battery life. Depending upon your flight time, you may need to purchase additional batteries to meet your airline's policies and regulations. Once on flight, most of the machines that the FAA approves of will easily fit underneath the seat in front of you or the overhead bin.

Although oxygen machine portable concentrators are incredibly durable and can handle storage in an overhead bin, it is important to remember that they are still "machines," with moving and mechanical parts, which can break or malfunction. It is vital to have a back-up plan should there be any issues with your oxygen therapy device. If you ever have any problems, Vitality Medical will honor the machine's warranty. In addition to assisting you with getting your machine serviced by the manufacturer, if you prefer, we will can also send you a complimentary oxygen device so that you do not need to go without therapy while your machine is being repaired by the manufacturer.
