Abstract

These days most of the Blood Pressure (BP) measuring devices are having inflatable cuff that is needed to be occluded on the patient's arm for measuring blood pressure. This technique is not suitable in cases where continuous measurement of BP is required. Therefore, this work is aimed at designing of non-invasive and continuously monitors the blood pressure by using Pulse Transit Time (PTT) technique. For taking out PTT both of the signals are extracted from the body of the patient with the help of bio sensors i.e. Electrocardiogram (ECG) sensor and Photoplethysmogram (PPG) sensor. PTT was measured by taking the peak to peak time difference of ECG signal and PPG signal and this PTT is indirectly correlated with blood pressure, based on which Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) is calculated.
