Arterial Pressure Variation
Quick Guide
Healthcare Re-imagined
GE is dedicated to helping you transform healthcare
delivery by driving critical breakthroughs in biology
and technology. Our expertise in medical imaging
and information technologies, medical diagnostics,
patient monitoring systems, drug discovery, and
biopharmaceutical manufacturing technologies is
enabling healthcare professionals around the world
to discover new ways to predict, diagnose and treat
disease earlier. We call this model of care “Early
Health.” The goal: to help clinicians detect disease
earlier, access more information and intervene
earlier with more targeted treatments, so they can
help their patients live their lives to the fullest.
Re-think, Re-discover, Re-invent, Re-imagine.
What is arterial pressure variation?
Positive pressure ventilation causes blood pressure
changes in the chest cavity: inspiratory phase increases
the pressure and expiratory phase decreases it.
The magnitude of these changes is dependent on the
fluid status of the patient. In hypovolemic patients
these swings are higher in amplitude compared to
normovolemic or hypervolemic patients. This is a well
known phenomenon.
The arterial pressure variation algorithm looks for
respiratory changes in the arterial blood pressure.
It only uses the arterial blood pressure analysis and
does not use any other parameter to recognize the
respiratory cycle.
Arterial pressure variation can be used to assess fluid
responsiveness continuously and without
extra procedures

Availability of the arterial pressure variation monitoring is
subject to the software version of the GE patient monitor.
In the S/5 product line L-ANE07(A) or L-ICU07(A) or newer
is required.
