Modern medicine and healthcare rely heavily on engineering to deliver improved prevention, diagnosis and treatment of illness. The proposed system uses a photo-plethysmography (PPG) technique. PPG sensors optically detects the blood volume changes in the microvascular bed of the tissue. The data which is obtained non-invasively through fingertip is first processed via analog filters and the output is sent to the microcontroller to estimate Heart Rate. The output from the filter is also sent to the computer through a microcontroller interface to be processed using MATLAB to estimate the Hemoglobin concentration Level. The estimated parameters are sent to the concerned person or to the doctor through GSM for real-time monitoring of the patient in critical situations.
