1. The accuracy of the Remler M2000, a semiautomatic portable blood pressure recorder, was assessed with the London School of Hygiene (LSH) and Hawkesley random-zero sphygmomanometers used as reference standards. 2. The Remler gave higher recordings than the LSH sphygmomanometer, the mean systolic and diastolic differences being 5.9 mmHg (P < 0.001) and 4.7 mmHg (P < 0.001) respectively. No significant difference was demonstrated between paired Remler and Hawkesley recordings. 3. When simultaneous paired LSH and Hawkesley sphygmomanometer recordings were compared, the LSH gave lower blood pressures: 7.1 mmHg (P < 0.001) for systolic and 3.6 mmHg (P < 0.001) for diastolic recordings. 4. The LSH sphygmomanometer underestimates blood pressure, partly due to a calibration error but also because the selection of end points for this device differs from other methods of blood pressure measurement.

Comparison of blood pressures obtained by femoral and common carotid artery cannulation has shown that in the rat anaesthetized with Nembutal an increase in blood pressure occurs after neck surgery and common carotid artery cannulation.

It is not only a problem for old age anyone. So, blood pressure is the one provides importance information with vital signs about cardiovascular health using oscillometric method. Unfortunately, this method required inflation and following deflation of the cuff. This method only gives instantaneous blood pressure and continuous measurement is not available. It is not available to the patients that required long term monitoring. To overcome this problem, the development of Continuous Non-Invasive Blood Pressure (NIBP) algorithm based on Pulse Transit Time (PTT) using two channel Photoplethysmograph (PPG) is proposed in this study. PPG is a non-invasive device for detecting blood volume changes can be affected by various physiological factors, analysis of the PPG signal can provide sufficient information on the human health condition; more specifically their cardio-vascular related performance. Literatures show that the PTT has linear relationship with blood pressure. Nevertheless, the determination of the model structure, order and real-time implementation to offer a continuous measurement of the PTT still remains challenging tasks in this area. PTT can be as index to monitor cardiovascular disease. In this project, dynamic model based on pulse transit time will be proposed to continuously monitor blood pressure by using PPG signals. Different kind of resolutions in microcontroller combined with PPG sensor will be used as well. MATLAB software is also been applied for PTT calculation based on two PPG sensors. PPG is method for detect blood volume changes with optical source transmitter send from one end and received the signal from another by receiver through body tissue as medium. MATLAB functions as Digital Signal Processing (DSP) for signals received in computer. Linear Regression technique and Fung's algorithm are applied to obtain the best fit line for all the points in order to systolic and diastolic blood pressure measurement. The results showed that the algorithm based on pulse transit time has been developed for the assessment of blood pressure and justify patient’ condition with 86.34% and 88.20% accuracy. Finally, this technique is a simple, user friendly and operator independent PPG system suitable for long term and wearable blood pressure monitor.
