Abstract | ||||
ABSTRACT Now a day Pulse Oximeter is a very important instrument in the surgical or intensive care units, as it’s a very fast and real time indication to the blood oxygen saturation level, which gives an indication of the patient’s status. Its theory of operation mainly depends on the phenomena of difference in the absorption of different wavelengths by body tissues and blood constitutes. The raw Pulse Oximeter (plethysmography) signal undergoes a lot of processing to calculate the desired values of the Blood Oxygen saturation .Many methods are employed either in time domain analysis or through frequency domain analysis. Each Method has its own advantage and disadvantage. By combining all these methods into a hybrid algorithm of processing taking into consideration the limitations and the most important advantages in each method, it is applicable to have an accurate method of calculating the SaO2. | ||||
