Is comparison of changes in cardiac output, assessed by different methods, better than only comparing cardiac output to the reference method?

Cardiac output by Portapres.
Portapres derives continuous estimates of cardiac output from the peripheral pulse and has the potential to be an extremely valuable physiological and clinical tool. We assessed Portapres estimates of cardiac output in healthy subjects at rest, during maximal treadmill exercise ( n = 8) and during decreases caused by orthostatic stress ( n = 8). Comparison with a rebreathing method indicated th...
متن کاملCardiac Output Assessed by Invasive and Minimally Invasive Techniques
Cardiac output (CO) measurement has long been considered essential to the assessment and guidance of therapeutic decisions in critically ill patients and for patients undergoing certain high-risk surgeries. Despite controversies, complications and inherent errors in measurement, pulmonary artery catheter (PAC) continuous and intermittent bolus techniques of CO measurement continue to be the gol...
متن کاملComparison of Cardiac Output Determinedby the Ballistocardiograph
a study of the latter method. In the form of an apparatus first developed in this country by Starr and his colleagues (2), the ballistocardiograph was designed to measure cardiac output. In normal resting subjects a reasonably satisfactory agreement with cardiac output measured by other techniques was obtained (3, 4). However, the validity of the ballistic record as a measure of cardiac output ...
متن کاملComparison between two methods of measuring cardiac output: misleading analyses?
Intraoperative awareness and the isolated forearm technique Sir,—The correspondence columns of The Times newspaper (April 8, 18, 1995) is not the forum to air the obviously diverging views on the use of the isolated forearm technique (IFT) to detect intraoperative awakening and the significance of this level of consciousness to anaesthetic practice. We were astounded to read that the IFT " has ...
متن کاملCardiac output during CPR: a comparison of two methods.
Simultaneous Fick and saline dilution methods were compared for measuring cardiac output during experimental cardiac arrest and resuscitation in anesthetized dogs. During cardiopulmonary resuscitation (CPR) cardiac output averaged 53 ± 30 ml/min-kg (42% of prearrest values). Values obtained using the Fick vs. saline methods were highly correlated (r = 0.96), and were not statistically different...
