Many patients who suffer from sleep apnea do not get proper diagnosis due to the discomfort and complicacy of the current diagnosis systems. The main focus of the project is to provide a solution for this problem by designing a home sleep apnea test. A patient's blood oxygen saturation level goes down during the apnea attack and this phenomenon can be detected using a pulse oximeter. Therefore a simple pulse oximeter is designed to provide data for the software that detects the risk of OSA. The software designed cannot detect sleep apnea with absolute certainty, but can provide with accurate risk warning for a patient who might be suffering. The output of the designed system is given by a software designed using MATLAB. Certain limitations exist in the development process and those are considered negligible for the scope of the project. However the solution of the limitations and alternate approach of the assumptions are discussed in details.
