Will My Insurance Include Oxygen Concentrator Expense?

without comments

When individuals with breathing problems are recently prescribed oxygen therapy, one of the first concerns is the cost. Oxygen therapy equipment can be expensive and many patients are unaware of insurance benefits available to them.

Oxygen is considered a medical treatment and must be prescribed by a doctor in order for you to receive it. Some patients may need only occasional or short term oxygen therapy while others require a long term use of oxygen therapy. Oxygen concentrator is one of the most popular oxygen delivery systems. They come in variety of sizes providing solutions for both home and travel.

Most insurance plans cover most of the cost provided your test results show that you require oxygen therapy. Private insurance coverage varies from company to company that is why it is important to check with your provider to see if your policy provides coverage.

In some cases, however, oxygen therapy is covered when your physician provides the results of pulse oximetry testing that prove that you need supplemental oxygen for your well-being. Pulse oximetry measures the amount of oxygen carried by the blood. This is a simple test that will help your physician make a diagnosis and qualify you for oxygen therapy to be covered by most insurance.

In Medicare case, it varies from state to state. Medicare will help pay for oxygen therapy equipment under these conditions:

In Medicare case, it varies from state to state. Medicare will help pay for oxygen therapy equipment under these conditions:

* Your physician confirms that you have lung disease and that oxygen therapy will help improve your condition.
* Your arterial blood gas level falls within a certain range.
* Other alternative methods have been tried and were not effective to you.

If you meet the above mentioned conditions, Medicare will help pay for:

* Oxygen supply systems (oxygen concentrators included)
* Oxygen contents
* Supplies for the delivery of oxygen

There are 2 exclusions for coverage of portable oxygen systems:

o If oxygen is provided for use during sleep only
o If portable oxygen is used only as a back up to a permanent oxygen system.

The Part Of Common Rail in Automobiles

without comments

Common Rail is basically an advanced fuel injection system which uses a tube to inject pressurized fuel directly into the car engine while maintaining a constant high pressure. The pressure that is present in the engine ensures that the fuel breaks down while administering the injection which helps to mix with the air. This helps to reduce the pollution normally caused by automobiles. When the air and the fuel is mixed the harmful emissions from the vehicle drops. There is an interesting history behind this engine’s emergence.

The first prototype of the common rail was introduced by Robert Huber in Switzerland in 1960. The design was taken ahead by Dr. Marco Ganser at the Swiss Federal Institute in Zurich. It was introduced to the international market as a product in the 1990s. During that time, it was fitted in with a commercial vehicle and sold.

The principle of the CRDi and the conventional engines is not all that different. The only difference is the traditional engine was controlled mechanically and the CRDi is controlled by an electronic control unit. The unit regulates the amount of fuel injected as well as the pressure utilized and required for both injection and combustion. The CRDi works with alongside the solenoid valve. This is an electromechanical valve that controls the flow of liquid or gas by stopping or running the flow of electric current. This valve is capable of controlling the quantity and the time of the fuel engine and calculate the amount of high pressure which is generated by the engine. The first few cars to be put on the market, with this engine were Alfa Romeo 156 in 1997 and Mercedes Benz C 220.

Working of this Engine

In a conventional engine system, the high pressure fuel pump stores a reservoir of fuel at a pressure of at about 29,000 pound-force per square inch (psi) in a common rail. This rail is, in reality, a tube which divides into a fuel injector valve which is fully computer controlled  and which has a precision-machined nozzle and a plunger which is driven by a solenoid valve. With the help of an on board computer, the engine regulates the fuel quantity and pressure. It also notes the time when the injection is actually injected and at the same time, increases the pressure at which the fuel is injected. This usually results in better combustion and fuel atomization which leads to lower exhaust emissions, increased fuel efficency and lower fuel consumption.

Like every new technology, CRDi has its own pros and cons. It has a couple of positive points such as, it offers 25% more power and torque as compared to convential engines. In countires such as India, since diesel is cheaper than petrol this form of injection works as an advantage. The disadvantage is, this form of engine is costlier than a conventional engine.

In the recent times, most big names in the automobile industry have adopted this engine. Some of these names are Fiat, Mitsubishi, Hyundai, Ford, Toyota, General Motors and so on.
