Secondly, we used the FloTrac/Vigileo system for CO measurements, an uncalibrated monitoring device based on the arterial pulse contour analysis without the need for external calibration.
Based on the influence of cycling intra-thoracic pressure on arterial pulse pressure or stroke volume, dynamic indicators such as arterial pulse pressure variation (PPV) or stroke volume variation (SVV) have been widely used as reliable predictors of fluid responsiveness [6 8].
Aim: Our aim was to investigate the acute and 24-hour (h) effects of high-intensity interval training (HIIT) and moderate continuous training (MCT) on arterial pulse wave reflection, an established marker of arterial stiffness and cardiovascular risk.
Monnet and colleagues have also described the effects of a tele-expiratory occlusion on arterial pulse pressure to predict the effects of volume expansion on CO [ 84].
One can estimate LV stroke volume based on the arterial pressure pulse contour.
Pulse contour analysis devices are based in the arterial pulse wave analysis and have the advantage of utilizing a preexisting arterial line, and most of them do not require external calibration.
Stepwise ventilator adjustments were made to FiO2, positive end-expiratory pressure, and respiratory rate based on continuous pulse oximetry and regularly performed arterial blood gases.
We hypothesized that using a treatment algorithm based on pulse pressure variation, cardiac index trending by radial artery pulse contour analysis, and mean arterial pressure in a study group (SG), would result in reduced complications, reduced length of hospital stay and quicker return of bowel movement postoperatively in abdominal surgical patients, when compared to a control group (CG).
Recently, several devices have been designed to assess cardiac function based on pulse contour analysis of an arterial waveform (Table 3).
