Pulse Oximeter Saves Protesters
There are many protests that have sprung up all over the Middle East. Even though the countries where the protests are occurring are different, their reasons are not. The reasons for the protests are all based on equality. The people of these countries are tired of unfair work environments, unfair employment opportunities, and brutality from the police and/or armed forces. We saw the protests first start in Tunisia where the people spoke out and the government stepped down.
This was then followed by Egypt, where the process lasted a few weeks. Now we are seeing the protests erupt in Libya, where the government is not reacting the same way. The government is turning to scare tactics and violence. There were also reports that air attacks were also ordered on the protesters. The unrest in the Middle East has even had a negative effect on the financial markets of the world. Oil prices have jumped up and stock markets have taken a dip.
Where Pulse Oximeter Began
A pulse oximeter is one of the most common and convenient medical health devices nowadays that anyone could use anywhere, anytime. Thus, it is an effective method of measuring the blood-oxygen saturation and pulse rate.
It is said that the original pulse oximeter was developed since 1935; it is just a two-wavelength ear saturation meter with red and green filters. This device only measures O2 saturation until it later switched to red and infrared filters. In 1949, some scientist added a pressure capsule to squeeze the blood out of the ear thus, this method is not used clinically because it is hard to implement. Therefore, in 1964, it appears an eight wavelength of light which is absolutely used to read ear oximeter. It is used usually in laboratories due to its size and cost.
10 Things You Need to Know When Purchasing a Pulse Oximeter
Purchasing a pulse oximeter is an extremely important health decision that you make in order to better your health and your life. This is a very easy to follow guide that will make it quite clear as to what you should look for when in the market to get such a device. Although there is a myriad number of different reasons why an individual may need this device the most common is that a person would need to monitor their pulse rate as well as oxygen levels. Here is the 10 things that you should know when purchasing a pulse oximeter:
1. Determine whether you need a pulse oximeter for a child or an adult. The reason why this is important is because these devices come in different sizes that are specifically made either for an adult or a child. The size difference is key to getting accurate readings.
How Does A Pulse Oximeter Work?
Pulse oximeter is used in measuring the level of oxygen carried by the hemoglobin in the entire body. The reading in the oximeter is an important indicator of lung and heart function. The level may be measured by analyzing a blood sample. But for a much quicker, less invasive process, a reading from the finger tip, earlobes or toes through the pulse oximeter can be used.
For each hemoglobin molecule, four oxygen molecules can be carried. Through pulse oximetry, the percentage of oxygen currently carried by the hemoglobin with maximum level of oxygen hemoglobin is able to carry is compared. The percentage is called the oxygen saturation level. Read more
