Edwards EV1000

Appendix G: Glossary
Alarms
Audible and visual indicators that notify operator that a
measured patient parameter is outside the alarm limits.
Alarm Limits
Maximum and minimum values for monitored patient
parameters.
Blood Pressure (BP)
Blood pressure measured from the ClearSight Finger Cuff.
Body Surface Area (BSA)
The calculated surface area of a human body.
Button
A screen image that, when touched, initiates an action or
provides access to a menu.
Cardiac Index (CI)
Cardiac output adjusted for body size.
Cardiac Output (CO)
Volume of blood ejected per minute from the heart into the
systemic circulation measured in liters per minute.
Central Venous Oxygen Saturation (ScvO
2
)
Percentage of hemoglobin saturated with oxygen in the
venous blood as measured in the superior vena cava (SVC).
Displayed as ScvO
2
.
Central Venous Pressure (CVP)
The average pressure in the superior vena cava measured
from the TruWave sensor.
Databox
A central input of multiple physiologic minimally invasive
signal sources which communicates with the EV1000
Monitor. The Databox can only be operated separately from
the Pump-Unit.
Default Settings
Initial operating conditions assumed by the system.
Estimated Oxygen Consumption (VO
2
e)
An expression of the estimated rate at which oxygen is used
by tissues, usually given in mL/min of oxygen consumed in 1
hour by 1 milligram dry weight of tissue. Calculated with
ScvO
2
.
Diastolic Pressure (DIA)
Diastolic pressure measured from the reconstructed brachial
arterial waveform.
Hemoglobin (HGB)
Oxygen carrying component of red blood cells. Volume of red
blood cells measured in grams per deciliter.
Heart Reference Sensor (HRS)
A system used for compensation of hydrostatic pressure due
to differences in height between the finger and heart.
Icon
An image that represents a specific screen, window, file, or
program.
Intervention
Steps taken to change a patient’s condition.
Mean Arterial Pressure (MAP)
Average systemic arterial blood pressure.
Mixed Venous Oxygen Saturation (SvO
2
)
Percentage of hemoglobin saturated with oxygen in the
venous blood as measured in the pulmonary artery. Displayed
as SvO
2
.
Oxygen Consumption (VO
2
)
An expression of the rate at which oxygen is used by tissues,
usually given in mL/min of oxygen consumed in 1 hour by 1
milligram dry weight of tissue. Calculated with SvO
2
.
Oxygen Delivery (DO
2
)
Amount of oxygen in milliliters per minute (mL/min)
delivered to the tissues.
Oxygen Delivery Index (DO
2
I)
Amount of oxygen in milliliters per minute (mL/min/m
2
)
delivered to the tissues, adjusted for body size.
Oximetry (Oxygen Saturation, ScvO
2
/SvO
2
)
Percentage of hemoglobin saturated with oxygen in the
blood.
Phlebostatic Axis
Reference axis in the patient that passes through the patient’s
right atrium in any anatomical plane.
Physiocal
A physiological calibration procedure used to obtain accurate
blood pressure readings from the artery of the finger.
