parameters in the OR
used in a clinician-directed PGDT
protocol are key to optimal volume
monitoring solutions that can be utilized perioperatively from the OR to the ICU.
Edwards’ hemodynamic monitoring solutions provide
advanced hemodynamic parameters shown to be more
informative in determining fluid responsiveness than
conventional pressure-based parameters, such as mean
arterial pressure (MAP) and central venous pressure (CVP). 1,2
Each of Edwards’ monitoring solutions offers continuous
dynamic and flow-based information which may be used in
Perioperative Goal-Directed Therapy (PGDT) to
consistently maintain your moderate to high-risk surgery
patients in the optimal volume range. 3
A clinician-directed treatment protocol, which
defines and treats to a goal, using advanced
hemodynamic parameters, with the objective
of consistently maintaining patients in the
optimal volume range during surgery.
Based on the complexity of each procedure, and patient risk factors, choose your preferred dynamic and
flow-based parameters and the appropriate Edwards’ hemodynamic monitoring solution to suit your
clinical approach and your moderate to high-risk surgical patients’ needs.
Edwards delivers an array of product support, tools and educational resources to help you advance patient care by extending
the benefits of reduced variability in volume administration to a broader range of patients, and more moderate
to high-risk surgical procedures.
30+ randomized controlled trials and 14+ meta-analyses have demonstrated clinical benefits of hemodynamic optimization utilizing a PGDT protocol and advanced parameters over standard volume management, including reducing post-surgical complications across a wide range of moderate to high-risk surgical populations. 4-7
Additionally, an extensive body of clinical evidence shows that goal-directed hemodynamic optimization of high-risk patients, initiated in the OR and continued in the ICU, not only improves short-term outcomes, but also increases long-term survival. 8-27

preload and stroke volume (SV)
Optimal volume management is possible when dynamic and
flow-based parameters are used within a protocol such as
Perioperative Goal-Directed Therapy (PGDT). 3,28-30
Managing volume administration is not the same as
consistently maintaining your patient in the optimal volume
in guiding volume administration.
Deviations from hemodynamic stability may increase with more invasive procedures
and/or more severe clinical conditions. Continuous access to advanced hemodynamic
parameters offers immediate insight into patient physiologic status, giving you the clarity to
make more informed volume administration decisions to help you consistently maintain your
patients in the optimal volume range.3,8,23,25,26,38-42
Conventional volume management, based on standard
monitoring including central venous pressure (CVP) , is
Clinical studies have shown CVP is not able to predict fluid
responsiveness1 and that changes in blood pressure cannot
be used to track changes in stroke volume (SV) or in cardiac
output (CO) induced by volume expansion. 2
Stroke Volume Variation (SVV) has demonstrated a higher
sensitivity and specificity in the assessment of circulating
blood volume when compared to conventional indicators of
volume status (HR, MAP, CVP) . 16,20,32
Stroke Volume Optimization (SV) 11,16-19,21-26
Stroke volume measurement with the ClearSight and FloTrac
systems enables an individualized approach for administering
fluid until SV reaches a plateau on the Frank-Starling curve, to
prevent hypovolemia and excessive fluid administration.
Stroke Volume Variation Optimization (SVV) 25
For control-ventilated patients, SVV has proved to be a highly
sensitive and specific indicator for pre-load responsiveness,
serving as an accurate marker of patient status on the
Oxygen Delivery Optimization (DO 2 with CCO) 23
Continuous cardiac output (CCO) measured by the ClearSight
and FloTrac systems can be used (in combination with SaO 2
and hemoglobin) to monitor and optimize DO 2 with fluid
(including red blood cells) and inotropic agents.
|SV protocol studies||Abdominal||Bowel||Cardiac||Cystectomy||General||Hip||Trauma||Vascular|
Currently, literature supports the use of SVV only on patients who are 100% mechanically (control mode) ventilated with tidal volumes of more than 8cc/kg and fixed respiratory rates.
Spontaneous Breathing 35,36
Currently, literature does not support the use of SVV with patients who are spontaneously breathing due to the irregular nature of rate and tidal volumes.
Arrhythmias can dramatically affect SVV values. Thus, the utility of SVV as a guide for volume resuscitation is greatest in absence of arrhythmias.
Increasing levels of positive end expiratory pressure (PEEP) may cause an increase in SVV, the effects of which may be corrected by additional volume resuscitation if warranted.
Vascular Tone 35,36
The effects of vasodilatation therapy may increase SVV and should be considered before treatment with additional volume.
