Invasive v. non-invasive measurement of arterial pressure. Comparison of two automatic methods and simultaneously measured direct intra-arterial pressure.
Two indirect arterial pressure monitors, the Finapres and the Accutorr, were investigated and compared with the direct measurement of intra-arterial pressure. Pressures in patients in a variety of circulatory states were measured and analysed in relation to two types of random error: first, the "intra-individual standard error" (within one session of measurement) and second, the "inter-individu...
متن کاملLevel of agreement between Nexfin non-invasive arterial pressure with invasive arterial pressure measurements in children.
BACKGROUND We compared Nexfin non-invasive arterial pressure measurements using a novel small finger cuff with intra-arterial pressure in the paediatric setting in order to establish the level of agreement between both methods. METHODS The study included 41 children aged 2-16 yr admitted for surgery or paediatric intensive care with an intra-arterial catheter as part of standard monitoring. V...
متن کاملAccuracy of non - invasive intracranial pressure measurement
Non-invasive measurement of intracranial pressure (ICP) reduces the complications and cost for both patient and health care systems. Improvement of non-invasive methods has led to development of systems for reproducing continuous, real-time non-invasive ICP signals. So far, non-invasive methods have been tailored for the patients with head trauma. We have used Schmidt’s auto-adaptive method to ...
متن کاملAdaptive Non-invasive Blood Pressure Measurement
In this paper oscillometric method is used to develop an adaptive non-invasive blood pressure measurement system. To overcome the drawback of conventional oscillometric method an algorithm is developed. During the time of deflation and inflation process the step size of pressure pumped and released using pump and valve respectively is varied adaptively by continuously monitoring the feedback wh...
متن کاملInvestigation of the agreement of a continuous non-invasive arterial pressure device in comparison with invasive radial artery measurement.
BACKGROUND Arterial pressure (AP) monitoring should be accurate, easy to use, free of risks, and ideally continuous. The continuous non-invasive arterial pressure (CNAP) device is non-invasive and provides continuous pressure readings. This study was performed to compare the agreement of CNAP and invasive AP monitoring. METHODS Ninety patients undergoing surgery under general anaesthesia were...
