So, it is not hard to see why prescription drugs can be expensive. This particularly holds true for drugs that cure rare diseases. If only a few people in a society are going to be buying a drug and using it for a cure then how is a drug company going to pay for the development costs that easily run into the millions of dollars?

For most people, pharmaceutical product development remains a huge mystery and rightfully so, because it is a very complex process. However; everyone benefits from the work that pharmaceutical product developers do when they shop at a drug store for anything from antibiotic ointment for a cut, to powerful prescription drugs for an illness. The search for new drugs and products to help people stay healthy never stops, because even when a cure for a disease is found, there are still diseases such as cancer for which a cure remains illusive.

The reason it takes so long for these tests to be completed, is that all drugs have to be studied for their long term as well as short term side effects. Not all drugs pass muster and if the side effects are found to be worse then the disease itself then the drug and all the work that went into it are discarded.

Pharmaceutical Product Development Costs - Who Pays ?

Should the cost be passed on to people that buy drugs for more common diseases, resulting in higher costs for them? Should the taxpayer pick up some of the cost of research? These are all questions that we all must face as pharmaceutical product development work moves into to the future.

Even after a new drug is discovered that is the cure for a disease, it can take up to a decade before it makes it to the consumer where it is needed. This is because, the FDA requires that all drugs be thoroughly tested, so no consumer can be hurt by the new drug.

The blood is, as many already know, red when oxygenated properly and blue when it contains no oxygen. Therefore, when a patient is not getting enough oxygen, the blood in his or her arteries will appear more purple than red - a dark, or bluish color.

A pulse oximeter will show how well the light is absorbed by the hemoglobin in the patients blood. When hemoglobin is fully saturated with oxygen it reflects light differently than hemoglobin levels that are not fully saturated, often due to some kind of pulmonary condition.

It is always a good reminder for yourself if you are a patient or a caregiver that the amount of oxygen prescribed should never be altered without the expressed permission of your doctor or other medical professional. However, the technology behind pulse oximeters is skyrocketing and high quality pulse oximeters are available right now on the market. Talk to your doctor, a pulse oximeter has no risks, and may be perfect for you!

When someone looks at his or her hands or feet, for example: he or she will see the reddish color of his or her arteries and the darker, more bluish color of the veins. The veins, which have dispersed oxygenated blood through the body, are now on the way back to the heart. The heart, which is oxygenated by the lungs then pumps fresh, oxygenated blood back into the bloodstream. Therefore, the blood pumping through the arteries should then under healthy conditions be a bright reddish color.

Do I Need A Pulse Oximeter?

The role of pulse oximeters is a non invasive method of determining the amount of oxygen from the heart contained in the blood or circulatory system. Often, a pulse oximeter is placed gently over your fingertip or your earlobe. In the most basic terms, a pulse oximeter is a measuring device with a light and a detector essentially of the color of someones blood.
