12.1 Acumen Hypotension Probability Indicator Software Feature
Acumen Hypotension Probability Indicator (HPI) software, when activated while using a FloTrac IQ sensor
connected to a radial arterial catheter, provides the clinician with the probability of a patient trending towards
a hypotensive event. A hypotensive event is defined as mean arterial pressure (MAP) < 65 mmHg for at least
one minute. The accuracy of the presented measurements are based upon several factors: the arterial line is
reliable (not damped), the connected arterial line pressure sensor is well aligned and properly zeroed, and
patient demographics (age, gender, height, and weight) have been entered into the device.
The Acumen HPI feature is intended for use in patients receiving advanced hemodynamic monitoring. The
additional quantitative information provided by using the Acumen HPI feature is for reference only and no
therapeutic decisions should be made based solely on the HPI parameter.
Precaution. If in the clinician’s judgement, a mean arterial pressure (MAP) value of < 65 mmHg would not
be meaningful for an individual patient, the clinician may choose to disable the HPI feature completely from
the parameter settings menu, or if the information available on the secondary screen is useful, may choose
to silence the P(↓BP) alarm from the Alarms/Targets popup screen.
CAUTION Inaccurate FT-CO measurements can be caused by factors such as:
• Improperly zeroed and/or leveled sensor/transducer
• Over- or under-damped pressure lines
• Excessive variations in blood pressure. Some conditions that cause BP variations
include, but are not limited to:
* Intra-aortic balloon pumps
• Any clinical situation where the arterial pressure is deemed inaccurate or not
representative of aortic pressure, including but not limited to:
* Extreme peripheral vasoconstriction which results in a compromised radial
arterial pressure waveform
* Hyperdynamic conditions as seen in post liver transplant
• Excessive patient movement
• Electrocautery or electrosurgical unit interference
