FloTrac system validated algorithm

Offers specific monitoring of a broader range of changing patient conditions

The FloTrac system algorithm is based on the principle that aortic pulse pressure (PP) is proportional to stroke volume (SV) and inversely related to aortic compliance. The algorithm compensates for the effects of compliance on PP based on age, gender, and body surface area (BSA).

The FloTrac system generation 4.0 has evolved based on a broad and expanding patient database that allows for ongoing system performance improvements. This expanded database in moderate- to high-risk surgical patients has informed the algorithm to recognize and adjust for more patient conditions.

Through continuous beat detection and analysis, the FloTrac system algorithm allows for the ongoing use of Stroke Volume Variation as a reliable indicator of preload responsiveness. The FloTrac system algorithm enables the display and use of SVV in patients with multiple premature atrial or ventricular contractions and allows you to guide volume resuscitation despite most arrhythmias.5,6,7

Estimation of Stroke Volume Variation by the SVVxtra algorithm is based on detection of abnormal beats, interpolation of remaining beats, restoration of missing beats, and calculation of Stroke Volume Variation5

Clinical application

The minimally-invasive FloTrac system offers continuous clinical decision support to enable proactive clinical decisions.

The FloTrac system provides access to pressure and flow parameters to help you evaluate hemodynamic instability including hypotension and guide appropriate treatment.

Recent studies show associations between intraoperative hypotension and increased risk of acute kidney injury (AKI) and myocardial injury- the leading cause of post-operative mortality within 30 days after surgery.

Advanced hemodynamic monitoring parameters CO, SV, SVV, SVR, and MAP provided by the FloTrac system can help you determine the cause of instability.

If the underlying cause of hemodynamic instability is related to flow generation, continuous parameters provided by the FloTrac system can help you determine appropriate fluid therapy.

Continuous assessment of pressure and flow parameters offers decision support to help manage the duration and severity of intraoperative hypotension episodes.

Frank-Starling relationship between preload and stroke volume

Frank-Starling relationship between preload and stroke volume (SV)

When managing perfusion, stroke volume can be optimized using the patient’s own Frank-Starling curve – a plot of SV vs. preload. The patient’s location on the curve can be determined by measuring changes in SV in response to change in preload using a fluid bolus challenge or passive leg raise (PLR).

Dynamic, flow-based parameters are more informative than conventional parameters in determining fluid responsiveness and may help guide individualized volume administration in patients and help you avoid excessive and insufficient volume administration.1-2

Additionally, stroke volume variation (SVV) has been proven to be a highly sensitive and specific indicator for preload responsiveness when managing volume. As a dynamic parameter, SVV has been shown to be an accurate predictor of fluid responsiveness in loading conditions induced by mechanical ventilation.3-4

Continuous assessment of your patient’s physiological needs

The minimally-invasive FloTrac system allows continuous assessment of your patient’s hemodynamic status, to help you detect sepsis and determine the appropriate fluid therapy.8,9

The FloTrac sensor can be used to measure flow-based parameters continuously prior to, during, and after the fluid administration portion of the 6-hour CMS bundle.

For A-line patients, the FloTrac sensor measures flow-based parameters continuously before and after a passive leg raise or fluid challenge.
