Pitfalls in haemodynamic monitoring based on the arterial pressure waveform
The accuracy of the arterial pressure-based cardiac output FloTrac-Vigileo system remains unacceptably low during haemodynamic instability. Data show that the measurement of cardiac output (CO) is strongly influenced by changes in factors that affect arterial blood pressure (ABP) - for example, vascular tone and compliance and the arterial site - independently of true changes in CO. Although in...
متن کاملPulse waveform analysis and arterial wall properties.
Risk factors for cardiovascular disease mediate their effects by altering the structure, properties, and function of wall and endothelial components of arterial blood vessels.1 The ability to detect and monitor change in the physical properties of arteries, representative of the cumulative and integrated influence of hemodynamic, metabolic, and inflammatory stimuli in impairing arterial wall in...
متن کاملSecond derivative of the finger arterial pressure waveform: an insight into dynamics of the peripheral arterial pressure pulse.
The study investigated second derivative of the finger arterial pressure waveform (SDFAP) in 120 healthy middle-aged subjects and in 24 subjects with essential hypertension. SDFAP consists of 5 sequential waves 'a'-'e'. Their normalized magnitudes (B/A, C/A, D/A, and E/A) were calculated. In multivariate regression analysis, B/A and C/A correlated only with age. D/A independently correlated wit...
متن کاملA System for Continuous Estimating and Monitoring Cardiac Output via Arterial Waveform Analysis
Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...
متن کاملAssociation of longer QT interval with arterial waveform and lower pulse pressure amplification: the Nagahama Study.
BACKGROUND Central systolic blood pressure (cSBP) has been postulated to correlate closely with cardiovascular risk. Identifying factors associated with cSBP is therefore important. Prolonged QT interval is known to be associated with cardiovascular outcomes and might also be associated with the arterial waveform and cSBP. We investigated the possible associations between electrocardiogram wave...
