Rechargeable batteries take their first use in a pulse oximeter

Batteries are truly the main component of portable computing that has allowed for medical devices to become so portable. Essentially the reason for this is that portability is a major factor that many individuals crave in the medical device field. We are a people always on the go and we like to go wherever we want at whatever time we want. The only way to do this is to have devices that are completely portable that can allow you to monitor your health on the go like a pulse oximeter. Well, disposable batteries were able to help in this regard in that they allowed for the devices to become completely mobile and you had no worry as to whether you really needed wires or any other types of cables. The problem was that the second that they ran out of the power you had to dispose of them in the trash. This proved to be an environmentally unfriendly act and there needed to be an innovation that would help with this. Well what happened next was that the use of rechargeable batteries began to be incorporated in the pulse oximeter device. This had two very important effects on the actually dynamics of using the device. First, it was much more environmentally friendly than the disposable varieties. Essentially you didn’t have to throw it away everytime that it ran out. This mean that there would be much less waste in our landfills and less impact on the earth. The other benefit is actually of a financial nature. When you throw away the power source you have to keep going back to buy one. However, if it is rechargeable you can just keep charging it back up again and reusing. This meant less cost for the individual as they didn’t need to keep buying new ones and can actually use the old one over and over again for better financial gain. A pulse oximeter works quite effectively to measure the pulse rate as well as the blood oxygen saturation of an individual The device is only a fraction of the size of a typical cell phone and thus it is extremely portable. It also is very accurate and instantly gives a reading of the oxygen saturation as well as pulse rate within seconds. By inserting your finger inside the portable device an infrared light passes through you finger. Hemoglobin absorbs light at different frequencies and as such the infrared light that goes through the finger bounces back to the oximeter device computer with a number that represents the oxygen levels of the body. This number means the world to people who live with conditions that require accurate monitoring of the oxygen levels in the body. Oximeter devices continue to break ground not only in the hospital setting but also the home setting as well. No longer do individuals need to be at their physician’s office or a hospital in order to take advantage of such a device to monitor their health. The newest generations of devices are not only extremely small and portable but they also are extremely affordable. So individuals living with various health conditions that are necessary to measure their oxygen levels can now use the device in the comfort of their home without ever having to worry about not monitoring their health on a continuous basis. The portability also allows them to take the device wherever they desire to go.
