Respiration is considered to be the most vital phenomenon of life. Problematic breathing, if untreated, may bring disastrous results. Sleep Apnea, being a silent killer, normally stays hidden from being diagnosed and the patient suffers the whole life till silently passing away. This study mainly focuses those patients who are totally unaware of the root cause of their frequent heart problems, restless sleep and anemia etc. For the research, we have utilized common tests like ECG and blood oxygen level and aimed to detect apnea in those patients who are being treated for other related problems but have hidden sleep apnea as one of the major cause of their frequent illness. On the other hand, for those patients who are suspected for sleep apnea, continuous and dynamic analysis of breathing ailment turns out to be a very irritating and expansive process as compared to continuous cardio and blood oxygen level analysis. We are following the path of ECG to mark breathing ailments along with the statistical analysis of different heart features followed by introduction of oxygen level analysis as one of the important factor. For this purpose we are using ECG, nasal breathing and Oxygen level data provided at MIT-BIH. © 2010 IEEE.
