Technical Definitions
This manual contains different technical terms. Note the following
definitions:
• Incubator temperature—The air temperature at a point 4" (10 cm)
above and centered over the mattress surface.
• Control temperature—The temperature controller’s set point
selected by the user.
• Average incubator temperature—The average of the maximum
and minimum incubator temperatures achieved during temperature
equilibrium.
• Incubator temperature equilibrium—The condition reached when
the average incubator temperature does not vary more than 1 °C
over a period of one hour. These measurements are taken at the
control temperatures of 90 °F (32 °C) and 97 °F (36 °C).
Technical Definitions
Chapter 1: Introduction
1
• Temperature uniformity—The amount by which the average
temperature of each of four points 4" (10 cm) above the mattress
surface differs from the average incubator temperature at incubator
temperature equilibrium.
• Temperature rise time—The time required for the incubator
temperature to rise 20 °F (11 °C), when the air control temperature
is at least 22 °F (12 °C) above the ambient temperature.
• Temperature overshoot—The amount by which incubator
temperature exceeds average incubator temperature at incubator
temperature equilibrium as a result of an increase in control
temperature. Additionally, the incubator temperature equilibrium
shall be restored within 15 min as a result of an increase in control
temperature value.
• Temperature correlation: Incubator temperature versus control
temperature—The amount the air temperature indicator at incubator
temperature equilibrium differs from the control temperature.
• Temperature correlation: Temperature indicator versus control
temperature—The amount the air temperature indicator in air mode
at incubator temperature equilibrium differs from the control
temperature.
• Measurement points—Measurements are taken at five points in a
plane parallel to and 4" (10 cm) above the mattress surface: One
point (A) is 4" (10 cm) above the center of the mattress, and the

Introduction
Overview
The Model C2000 Isolette® Infant Incubator provides a therapeutic
environment for the care for low birth-weight neonates. The Model
C2000 Isolette® Infant Incubator provides the following features:
Introduction
Chapter 1: Introduction
1
• Data trending—The unit graphically trends critical data, such as air
temperature, skin temperature, heater power, oxygen, and humidity,
for intervals of 12 to 24 hours, and up to seven days for weight
changes.
• Thermal performance—The unit’s thermal management capabilities
provide a patented dual-air curtain that reduces radiant heat loss
from the infant by warming the surface of the inner hood.
• Bi-directional airflow—Bi-directional airflow minimizes temperature
fluctuations within the incubator when the access doors are opened.
A microprocessor controller quickly and accurately regulates
temperature, humidity, and oxygen levels within the incubator.
• Low operating sound levels—The unit’s low operating sound levels
ensure a developmentally-supportive environment for infants.
• Centralized care for multiple births—The unit allows for co-bedding,
enabling the caregiver to monitor and care for multiple births. The
incubator mattress provides the needed space to care for two
infants and enough room for both to grow comfortably.
• Integrated x-ray cassette tray—Located beneath the mattress, the xray cassette tray slides out smoothly to avoid disturbing the baby.
• Infant access—By using the front and side access, two clinicians
can simultaneously care for an infant while he or she remains in the
incubator, reducing handling and adverse stimulation.
• Servo-controlled oxygen—Oxygen delivery is simplified by selecting
and controlling whole hood oxygen concentrations from 21% to
65%. Calibration can be performed in room air or in 100% oxygen.
The process can be done while the caregiver monitors the infant,
without interfering with the thermal environment.
• Servo-controlled humidity—The front-loading humidity reservoir
requires filling only once every 24 hours. The caregiver can set the
desired relative humidity, minimizing the infant’s evaporative heat
loss.

High and Low Air and Skin Temperature Alarms
Alarms
Chapter 2: Troubleshooting Procedures
The high and low air or skin temperature alarms activate if the skin or
air temperature fluctuates from the set temperature as follows:
2
• Skin temperature—± 1.0 °C
• Air temperature—+1.5 °C, -2.5 °C
NOTE:
The skin temperature limits may also be set to ±0.5 °C. Refer to
“Installation and Set-up” on page 6-13.
A temperature below the air or skin set temperature is indicated by the
message Low Air Temperature or Low Skin Temperature in the
message center, an audible alarm, flashing indicators, and a low
temperature reading. A temperature above the air or skin set
temperature is indicated by the message High Air Temperature or
High Skin Temperature in the message center, an audible tone,
flashing indicators, and a high temperature reading.
The high and low air or skin temperature alarms are self-resetting; that
is, if the alarm condition is corrected, the alarm automatically silences
and the Alarm indicators turn off. To silence the audible portion of the
High and Low Air or Skin Temperature alarms, press the
Silence/Reset key; the activation of other audible and visual alarms are
not affected by use of the 15-minute audible alarm silence. When the
alarm silences, the Alarm indicators remain on until the alarm condition
is corrected. If the alarm condition is not corrected within 15 minutes,
the alarm sounds.
In addition, if the air or skin set temperature changes (either high or low)
after the incubator is in operation, the High Temperature and Low
Temperature alarms automatically silence for a specific amount of time
after the operator raises or lowers the air or skin set temperature from
the current temperature. As a general rule, the greater the change from
the current incubator temperature, the longer the alarm remains silent.
If the incubator fails to reach the new set temperature after the specified
time, the alarm sounds.
Alternately, before changing the current air or skin set temperature, the
operator may press the Silence/Reset key to place the unit in
