HemoSphere Advanced Monitor 1 Introduction

NOTE Cardiac output calculated with the HemoSphere pressure cable may differ from that
calculated with the HemoSphere Swan-Ganz module due to methodological and
algorithmic differences.
Table 1-7 HemoSphere pressure cable key parameters description
Parameter Description Technology
cardiac output (CO) continuous assessment of the volume of
blood pumped by the heart measured in
liters per minute using the existing
arterial pressure waveform and FloTrac
system algorithm
FloTrac or FloTrac IQ sensor
continuous cardiac index
(CI)
continuous cardiac output relative to
body surface area (BSA)
FloTrac or FloTrac IQ sensor
central venous pressure
(CVP)
central venous blood pressure TruWave pressure transducer at
central venous catheter line
diastolic blood pressure
(DIA)
diastolic blood pressure FloTrac sensor, FloTrac IQ sensor, or
TruWave pressure transducer
maximal slope of the
arterial pressure upstroke
(dP/dt)*
measure of the changes in contractility of
the left ventricle*
FloTrac IQ sensor
dynamic elastance
(Ea
dyn
)*
measure of afterload to the left ventricle
by the arterial system (arterial elastance)
relative to the left ventricular elastance*
FloTrac IQ sensor
hypotension probability
[P(↓BP)]*
probability that the patient may be
trending toward a hypotensive event
(MAP<65 mmHg), displayed as a
percentage*
FloTrac IQ sensor
mean arterial pressure
(MAP)
averaged systemic blood pressure over
one cardiac cycle
FloTrac sensor, FloTrac IQ sensor, or
TruWave pressure transducer
mean pulmonary artery
pressure (MPAP)

pressure over one cardiac cycle
TruWave sensor at pulmonary artery
catheter line
pulse rate (PR) number of arterial blood pressure pulses
per minute
FloTrac sensor, FloTrac IQ sensor, or
Truwave pressure transducer
stroke volume (SV) volume of blood pumped with each heart
beat
FloTrac or FloTrac IQ sensor
stroke volume index (SVI) stroke volume relative to body surface
area (BSA)
FloTrac or FloTrac IQ sensor
systemic vascular
resistance (SVR)
a derived measure of impedance to blood
flow from left ventricle (afterload)
FloTrac or FloTrac IQ sensor
systemic vascular
resistance index (SVRI)
systemic vascular resistance relative to
body surface area (BSA)
FloTrac or FloTrac IQ sensor
stroke volume variation
(SVV)
the percent difference between SVmin,
max and mean
FloTrac or FloTrac IQ sensor
systolic pressure (SYS) systolic blood pressure FloTrac sensor, FloTrac IQ sensor, or
Truwave pressure transducer
*HPI parameters are available when using a FloTrac IQ sensor and if the HPI feature is activated. Activation is only available
in certain areas. Please contact your local Edwards representative for more information on enabling this advanced feature.
