Project on Pulse Oximeter

For patients at risk of respiratory failure, it is important to monitor the blood oxygen saturation of such individuals to ensure proper perfusion of blood in their system. Preferably this information should be received on a continuous basis. Both of these objectives can be reached via the non−invasive method of pulse oximetry. This is currently used in hospital/clinical settings, however uses wires which in effect bound an individual to an area. The purpose is to create a clinical diagnostic system which takes a few physiologically relevant signals and transmits them wirelessly to a base station.  This project specifically deals with the design of a wireless pulse oximeter for this system. By using the principle of differential light absorption and the assumption that the transmission of light through the arterial bed is influenced only by the relative concentrations of oxygenated and reduced hemoglobin and their  absorption coefficients at the two wavelengths, light intensity will decrease logarithmically according to Beer−Lambert’s law.The theory behind our device, hardware design and the experimental results of the system are presented.

    Pulse oximeter is one of the devices that deserve our attention.

    Pulse oximeter is a device to determine how many percent of oxygen does your body has and If I'm not wrong below 93 is not normal and need to support an oxygen machine. Thanks for sharing it was really a nice and informative bllog.

    My Auntie has been confined for three days due to difficulty in breathing and one day I saw the nurse using this device and ask her what's that for and she told me that this is to check or monitor the level of oxygen on her body. Just sharing=)

    Great share Lexmark, This device is really important, I've also read that this can monitor the abrupt decrease of oxygen. Thanks for sharing.

    Thanks , I have recently been looking for info approximately this
    subject for a long time and yours is the best I have found out
    so far. However, what concerning the bottom line? Are you positive in regards to the supply?
