Abstract
In in this study ultrasonic method was applied for measuring blood pressure (BP). First, a novel method is proposed to measure mean arterial pressure (MAP), diastolic blood pressure (DBP) and systolic blood pressure (SBP) using ultrasonic sensors. The proposed algorithm is implemented by measuring the diameter of the artery and the speed of blood flow based on Doppler physical phenomena so the blood pressure can be calculated. The results of the proposed algorithm for MAP, SBP, and DBP hypertension analyses were evaluated with the results of Association for the Advancement of Medical Instrumentation (AAMI standard) for all three cases and their mean error rate for the worst case was -0.233mmHg and the standard deviation for 422 samples taken from individuals in the worst case was 4.53 mmHg that meets the standard requirements. Also, according to the British Hypertension Society (BHS) standard, a proposed algorithm for estimating blood pressure for all three cases of MAP, DBP, and SBP has Grade A, indicating high accuracy in measuring and using the most effective variables in the diagnosis of hypertension in the human body. The proposed algorithm in BP estimation is non-invasive, cuff-less, no calibration, and only based on using the ultrasonic sensor.

Cardiovascular disease (CVD) is one of the main causes of death in the world
Blood pressure (BP) is one of the most important parameters of the human body where by its measurement, very useful information can be provided for the physician
A new method based on the use of ultrasonic signals for BP measurement is presented, which is a non-invasive and continuous method and does not require calibration
Summary
Cardiovascular disease (CVD) is one of the main causes of death in the world. According to the European Heart Institute reports, 4.1 million people die from the disease each year [1]. Long-term hypertension is one of the most important risk factors for coronary artery disease, stroke, heart failure, atrial fibrillation, peripheral vascular disease, vision loss, chronic kidney disease and dementia [15,16,17]. Its value depends on the functional factors of the cardiovascular system, such as the strength of the cardiac extrusion, the flexibility, and the thickness of the vessel wall [5]. This pressure applied to the vessel wall differs in the two modes of cardiac function and resting phase, which are termed the systolic pressure-maximum pressure (SBP) and the diastolic pressure-minimum pressure (DBP) respectively [6]
