Home Oxygen Therapy

Home oxygen therapy is usually recommended when the lungs are unable to supply enough oxygen to the blood. This condition is known as hypoxemia. This therapy increases the amount of oxygen in the blood, protects the heart, reduces shortness of breath, and prevents other cardiovascular problems. The air we breathe in, contains 21% oxygen whereas, the oxygen received at home with the help of the therapy, is close to 100% pure oxygen.

There are mainly three types of systems available to provide oxygen at home: liquid oxygen, compressed oxygen (tanks), and oxygen concentrators. Usually an oxygen mask or a nasal cannula (a two-pronged lightweight tube) is used to inhale oxygen.

Living with a Portable Oxygen Concentrator

Living with Supplemental Oxygen

It os now more than a decade since my stepfather nearly died from lung failure. As with too many people who stopped smoking some fifteen years before, the damage had been done. After his hospital stay and the begining of his recovery he had to live with lsupplemental oxygen continuously.

The initial period for everyone who must have supplemental oxygen is one of adjustment and this is not an easy time.

The psychological and emotional difficulties are usually much greater than the physical ones, even though people around you will normally focus on those they can see - i.e. the physical ones: the act of breathing, the tubing (cannulas) you u

The Incredibly Beneficial Uses of Portable Oxygen Concentrators

Oxygen therapy is an essential treatment option for patients suffering from a number of respiratory diseases like chronic obstructive pulmonary disease or COPD. Scientists have thought up different ways of solving this problem and have finally come up with two technical solutions for long-term oxygen treatment: portable oxygen concentrators (POC), and liquid oxygen tanks. Long-term oxygen treatment is said to be an oxygen therapy that lasts for more than 15 hours a day.

POCs are machines that provide supplemental oxygen to a patient, by compressing atmospheric air to almost 4 atmospheres of pressure and discarding nitrogen out of this compressed air. This increases the concentration of oxygen in the compressed air. The older versions of these concentrators were bulky and unreliable. However, today's innovative concentrators are smaller in size, more reliable, i.e., they produce between 1 - 6 liters per minute (LPM) of Oxygen, and offer a high level of convenience and mobility. Liquid oxygen and compressed oxygen systems require large cylinders that have to be refilled and stored, or handled with care. However, a POC can be simply plugged into any electrical outlet, including a vehicle DC adapter. They also have rechargeable batteries that may be used when away from a power outlet.

Benefits of POC

Those suffering from a number of health problems might require supplemental oxygen as a part of their treatment protocol. There are essentially three basic methods to receive oxygen, namely through liquid oxygen tanks, compressed oxygen cylinders, and concentrators. The concentrators have a number of uses and benefits, when it comes to issues like the storage, travel, and safety. Here are some of the uses of POC:

Uses: The biggest advantage of a portable oxygen concentrator is its ease of use feature. User-friendly and easy to use, these systems are simply plugged into a basic electrical outlet. Most other systems like liquid oxygen tanks require large tanks, which are very heavy and are not designed to be portable.

Storage Purposes: Unlike compressed and liquid oxygen systems that require large cylinders to be stored in, they are easy to store.

Travel: Some portable concentrators can be plugged into the car's accessory outlet and come with special features like rechargeable batteries. Compressed tanks are not permitted in flights as they are classified as hazardous to life, whereas some concentrators have been approved by the FAA (Federal Aviation Administration).

Delivery: Compressed and liquid oxygen systems tanks need to be refilled from an equipment store. This can be highly inconvenient, as there is a set schedule involved. A concentrator on the other hand, does not require these tanks so there is no need to wait for delivery.

Safety: The pressure that compressed oxygen tanks are under is very high. So, they have to be handled with extreme care all the time. A concentrator does not have any of these safety hazards.

These benefits make a POC a better option than the other systems which involve storage of hazardous tanks at home.

Researchers Develop Transparent Solar Concentrator That Could Cover Windows, Electronics

Scientists at Michigan State University announced this week the creation of a "transparent luminescent solar concentrator" that could turn windows and even cellphone screens into solar-power generators.



This technology could mean that one day entire skyscrapers might be able to generate solar power without blocking out light or ruining tenants' views.

The material works by absorbing light in the invisible spectrum (ultraviolet and near infrared) and then re-emitting it in the infrared. The infrared light is then channeled to the edge of the clear surface, where thin strips of photovoltaic cells generate the power.

Because we cannot see infrared or ultraviolet light, the material remains transparent even while concentrating sunlight. Previous luminescent solar concentrators have been developed, but they emitted light in the visible spectrum, creating a stained-glass effect.

"No one wants to sit behind colored glass," Richard Lunt, who leads the lab researching this new technology, said in a press release. He likened the experience to "working in a disco."

The new technology is promising, but needs to be made more efficient. Researchers say that the solar conversion efficiency is around one percent. Ideally, this could be increased to more than five percent. The researchers note that the highest conversion efficiency achieved by a non-transparent luminescent solar concentrator is about seven percent.

According to the National Renewable Energy Laboratory, solar technologies can have efficiencies ranging from eight percent to almost 45 percent, depending on the particular properties desired. A conventional panel like the kind typically installed on home rooftops has an efficiency of around 15 percent.

Luminescent solar concentrators are less efficient than traditional photovoltaics, which absorb a larger range of wavelengths, but they could allow energy harvesting on surfaces that would otherwise never be used to generate power.

Rumors surfaced earlier this year that Apple's iPhone 6 will include a different type of solar screen, but you may not want to get your hopes up just yet. Forbes contributor Nigam Arora wrote in January that the technology is not quite ready. A "screen with a laminate of film containing solar cells is likely in iPhone 7 but not in iPhone 6."

The transparent technology could be used in a variety of applications, Lunt said, and its affordability means it has the potential for eventual commercial or industrial use. "Ultimately we want to make solar harvesting surfaces that you do not even know are there," he said. The researchers' findings were published in the journal Advanced Optical Materials in July.

Mother kicked off Frontier flight over sick son's oxygen tank

A Las Vegas mother claims she was kicked off a flight to Orlando for bringing a portable oxygen tank onboard to be used by her infant son.

Yamile Quintero, who says her son Roman suffers from a heart murmur and has a chronic lung disease which makes it difficult for him to breathe, says she called Frontier before flying to confirm that the type of tank she had was acceptable.

"I asked and they were like, 'Yeah, as long as it's portable oxygen, you're fine. You can get on the plane," she told KSNV.

Quintero had planned to fly to Orlando to visit family over Mother's Day weekend and this was her first time bringing Roman on a plane.

But after boarding the aircraft, Quintero says a flight attendant told her she was not able to fly with the oxygen tank and was asked to disembark.

The FAA allows some portable oxygen tanks, but can also require a note from a doctor-- something Quintero was not aware of. Frontier's website also has a list of FAA approved oxygen concentrators, but the mother said she thought she had gone through the proper channels to verify that her son would have what he needed to fly.

A Frontier Airlines spokesperson told local station KRTK that Quintero needed an FAA-approved oxygen concentrator which is different from a tank.

Richard Oliver, a Frontier Airlines representative, said, "Our agent responded and said yes portable oxygen is allowed on the plane and continues to say that if you want to make sure your device is allowed on the plane, you can check out website."

Quintero says she was still "humiliated" by the ordeal.

"I did all the proper protocols. I called, I double checked at the door, I double checked at the gate, I double checked everywhere. I called and I did everything. I followed all the procedures and I'm getting kicked off the plane like I'm some type of criminal," she said.

"Multiple times I stated it was a portable oxygen tank. And they said it was fine, and it wasn't. And they kicked me off the plane for it and humiliated me."

Oliver said the airline apologized to Quintero and offered her son an approved oxygen concentrator. "We do certainly apologize for the confusion that occurred at the airport."

Though she did eventually make it to Orlando, the mother wasn't satisfied with the airline's response.

"They took my first Mother's Day away from me."
