DESING OF A HYPOXIA DEVICE DETECTOR WITH WIRELESS ALERT

In the present work, the development of a non-invasive pulse oximeter is proposed, which will send a warning message in possible case of hypoxia.  The oximeter will generate a red light and an infrared light, both lights will be reflected on the skin and captured by a photodiode, that signal will be processed in a microcontroller for calculating the oxygen saturation in the blood (SPO2). That will happen by making a comparative between the light absorbed by oxyhemoglobin and deoxyhemoglobin. In such a way that if SPO2 is below the normal medical parameters, the device will be able to send an alert to another similar device by wireless communication. This device has been proposed to be used by people with cardiopulmonary problems, people who are under anesthesia, as well as people who work in places at high altitudes, such as mountain climbers.
