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

remaining four points (B) are the centers of four areas formed by lines that divide both the width and length into two parts (see figure 1-7 on page 1-8).

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.
