Abstract
How to compute oxygenation accurately is very important for understanding patient's condition with breathing problem.
As development of oximeter, it's easier to obtain oxygen saturation with noninvasive way.
Although oximeters are widely used in hospital but not home because the price of the oximeter is a little bit high.
Some parts of elderly or patients are taken care of at home by nurses ,
even a nurse hardly monitors the patient's condition during the night,
so it could happen that patient is hypoxic for a long time but the nurse doesn't realize it.
In this case, if the finger is worn by a probe connected to oximeter. Once hypoxia happens, the oximeter will alarms and inform us so that we can send the patient to the hospital in time!!
Because the reasons we said, we try to design a device for home care that can monitor oxygen saturation all the time.
In order to be used at home, our device requires small size .
We attempt to monitor oxygenation with a simple way that differs from the method of pulse oximeter.
And we hope our device be more sensitive than the regular pulse oximeter, then it will alarm earlier when hypoxia happens.
Our thesis includes optical method, structure of the device, experiments , device testing.
First, we will introduce the principle of pulse oximeter and our method, then explain how does the device work.
We will do some experiments to verify the device and design a flow chart of detecting hypoxia in real time.
Finally, we will have some discussions and conclusions.
