Heart disease and stroke are among the world’s leading causes of death and disability. The higher stress level, inactive lifestyle, unawareness about risk factors such as overweight, high cholesterol level, hypertension, diabetes etc. results in increasing risk of cardiovascular diseases. Heart patients have to follow different tests for diagnosis as well as for treatment. The presented techniques such as ECG are expensive, invasive and can be applied only under clinical observation. Development of noninvasive, accurate physiological parameter monitor which can be used at personal as well as clinical level is among the main fields in biomedical engineering. The popularity of smart phones is increasing at a very tremendous rate. A mobile phone can serve as an accurate monitor for several physiological variables, based on its ability to record and analyze the varying color signals of a fingertip placed in contact with its optical sensor. In this paper, we have used smartphone camera for collecting the PPG videos. At the same time pulse rate and oxygen saturation level is measured using standard pulse oxymeter. The patient is asked to breathe by metronome breathing technique. ICA algorithm is used for removing the motion artifact. As per the study and observations, the use of Smart phones for the estimation of the heart rate, respiration rate and oxygen saturation level is conceivable.
Keywords- PPG (photoplenthesmography), HR (heart rate), RR (respiration rate), SpO2 (oxygen saturation level), MA (motion artifact), physiological parameter monitor, pulse
