Blood Pressure clinical trials

Study on Pressure Values Measured on Three Alternative Sites of the Lower Limbs Compared to the Arm

Non-invasive measurement of blood pressure is an instrument governed nursing routine care. The use of an automated oscillometric cuff is a common technique and validated if this is done on the arm with a suitable cuff, positioned opposite the brachial artery and up to the right atrium (the brachial site) . If cons-indication to use the brachial site, measurements are frequently performed at the ankle, calf or thigh. Among the blood pressure values measured on the 3 sites of the lower limb (thigh, calf or ankle), it may be a specific property of which the observed values are closest to the reference values (brachial). The objective of this study is to measure the non-invasive blood pressure values at three sites of the lower limb, to compare the reference value to determine which alternative site should be preferred when the reference measurement is not feasible . We want to determine the alternative site to obtain values as close as the measured values of the reference site. The three study sites are the thigh, calf and ankle. The reference site recommended for monitoring non-invasive blood pressureis the arm. It is also assessing the impact of certain parameters on the primary endpoint: - Physiological parameters: gender, weight, height, age, systolic blood pressure reference, listed measures. - A parameter related to measurement: discomfort felt when the blood pressure outlet. - Exposure setting: smoking.
