ObjectiveTo evaluate the reliability, by comparison with established techniques, of a new method to assess cardiac output, called pressure recording analytical method (PRAM), deriving from the analysis of the arterial pressure profile in the time domain the arterial-pressure-blood flow relationship. DesignCriterion standard. SettingHemodynamics laboratory at an university medical center. PatientsTwenty-two hemodynamically stable cardiac patients scheduled for diagnostic right and left heart… Expand
Pressure recording analytical method (PRAM) for measurement of cardiac output during various haemodynamic states.
TLDR
In a porcine model, PRAM is a reliable tool to detect changes in cardiac output in pigs and has ability as a basic research tool and is demonstrated accuracy during various haemodynamic states. Expand
Cardiac output monitoring by pressure recording analytical method in cardiac surgery.
TLDR
Under the studied conditions, good agreement between PRAM data and ThD measurements is demonstrated, and this new method has shown to be accurate for real-time monitoring of cardiac output in cardiac surgery. Expand
Systemic arterial waveform analysis and assessment of blood flow during extracorporeal circulation
TLDR
PRAM provided accurate, continuous quantification of peripheral blood flow during each phase of cardiac surgery, including ECC, and allowed early recognition of patients with low CO during weaning from the pump. Expand
Cardiac index validation using the pressure recording analytic method in unstable patients.
TLDR
This study showed that PRAM, a minimally invasive method for cardiac index assessment, is clinically useful even in unstable patients such as those receiving intra-aortic balloon pump and/or ongoing high doses of a inotropic drugs because of a low cardiac output syndrome but without atrial fibrillation. Expand
Less invasive determination of cardiac output from the arterial pressure by aortic diameter-calibrated pulse contour.
TLDR
After diameter-calibration, the improved modelflow pulse contour method reliably estimates cardiac output without the need of a calibration with thermodilution, leading to a less invasive cardiac output monitoring method. Expand
Cardiac index assessment by the pressure recording analytic method in unstable patients with atrial fibrillation.
TLDR
It was concluded that PRAM did not compare well with thermodilution in unstable patients with atrial fibrillation and should not be considered as a standalone method for cardiac index measurement in hemodynamically unstable patients. Expand
Assessment of cardiac output in children: A comparison between the pressure recording analytical method and Doppler echocardiography*
TLDR
In the range of ages evaluated, PRAM provides reliable estimates of cardiac output when compared with noninvasive techniques. Expand
Lack of agreement between pulmonary arterial thermodilution cardiac output and the pressure recording analytical method in postoperative cardiac surgery patients.
TLDR
The results question the reliability of the PRAM technology for the determination of CO in postoperative cardiac surgery patients. Expand
Continuous cardiac output monitoring with an uncalibrated pulse contour method in patients supported with mechanical pulsatile assist device.
TLDR
Good agreements were demonstrated between PRAM-CO, ThD-CCO and LVAD-CO and may be a complementary tool in the hemodynamic assessment of patients supported with a VAD. Expand
Cardiac output estimation by pulse wave analysis using the pressure recording analytical method and intermittent pulmonary artery thermodilution
TLDR
Using the system's electronic waveform filter PRAM-CO shows good agreement and trending ability compared with PATD-CO in adults after off-pump coronary artery bypass surgery, using Bland-Altman analysis. Expand

Clinical assessment of cardiac output.
TLDR
Of the available methods to determine cardiac output, thermodilution is the most practical, although it has its difficulties and care has to be exercised in its use. Expand
Noninvasive cardiac output measurement by arterial pulse analysis compared with inert gas rebreathing.
TLDR
Noninvasive cardiac output (CO) measured by arterial pulse analysis was compared with that measured by inert gas rebreathing in six healthy male volunteers to show a substantial increase in CO that was mainly related to an increase in heart rate. Expand
Continuous stroke volume monitoring by modelling flow from non-invasive measurement of arterial pressure in humans under orthostatic stress.
TLDR
Due to orthostasis, changes in the aortic transmural pressure may lead to an offset in MFSV from IAP, however, Modelflow correctly calculated aortsic flow from non-invasively determined finger pressure during orthostatic stress. Expand
Continuous cardiac output monitoring by pulse contour during cardiac surgery.
TLDR
It is concluded that the corrected pulse contour method estimates cardiac output accurately, even when heart rate, blood pressure, and total peripheral resistance change substantially. Expand
Non-invasive cardiac output assessment during moderate exercise: pulse contour compared with CO2 rebreathing.
TLDR
The results suggest that Modelflow 2.1 is not an accurate method for estimating CO from non-invasive blood pressure data collected by Portapres during exercise at up to 60% of the individual POpeak corresponding with daily life activity. Expand
Continuous, less invasive, hemodynamic monitoring in intensive care after cardiac surgery.
TLDR
It is concluded that COart correlates well with COpa and can be used to calibrate COpc and COpc agree with thermodilution-based CO and SVR without recalibration for 24 hours. Expand

Evaluation of pulse contour methods in calculating stroke volume from pulmonary artery pressure curve (comparison with aortic pressure curve).
TLDR
The employment of pulmonary arterial pressure curves in assessing stroke volume may be more useful clinically since its recording can be carried out more safely than recordings of aortic pressure curves. Expand
Beat-to-beat estimation of peripheral resistance and arterial compliance during pressure transients.
TLDR
It is indicated that peripheral resistance and total arterial compliance can be estimated in vivo on a beat-to-beat basis, even during hemodynamic transients. Expand
Computation of aortic flow from pressure in humans using a nonlinear, three-element model.
TLDR
Aortic flow pulsations from arterial pressure was computed by simulating a nonlinear, time-varying three-element model of aortic input impedance by observing quantitative changes in cardiac output that occurred either during changes in the state of the patient or subsequent to vasoactive drugs.
