Operating modes
The Care Plus has two operating modes: the air control (or manual) mode, which
adjusts heater output to achieve a target air temperature; and the patient control
(or servo) mode, which adjusts the incubator temperature to achieve a target infant
skin temperature. In both modes, the target temperature appears in the Control
Temperature display on the front of the controller and can be adjusted using the
temperature switches (
?
and
M
).
To distinguish between control temperatures in the different modes, this manual uses
the term “air control temperature” for the control temperature in the air control mode
and the term “patient control temperature” for the control temperature in the patient
control mode.
Note: This section briefly mentions displays, controls, and alarms that play a
significant role in the air control and patient control modes. For further information,
refer to the appropriate section “Controls and displays” or “Alarms.”
The air control (manual) mode
The air control mode compares the air temperature to the air control temperature to
determine if the heater should be switched on or off. If the air temperature is too high,
the heater switches off. If the air temperature is too low, the heater switches on.
Air control temperature
The air control mode lets you enter air control range temperatures from 20 to 37°C
(68.0 to 98.6°F) using the temperature switches (
?
and
M
). Pressing the Override
switch when the air control temperature is 37°C (98.6°F) lets you increase the air
control temperature to 39.0°C (102.2°F).
Control temperature alarm
The control temperature alarm triggers if the air temperature exceeds a normal range
air control temperature by more than 1.5°C (2.7°F) or if the air temperature falls more
than 3.0°C (5.4°F) below the air control temperature. For air control temperatures
above 37°C, the control temperature alarm triggers if the air temperature exceeds the
air control temperature by more than 1.0°C (1.8°F).
To avoid unnecessary alarms, the control temperature alarm does not trigger during
the first 30 minutes after power is switched on and for 15 minutes after you change
the air control temperature or enter the air control mode from the patient control
mode. During this period, normal incubator alarm routines verify proper operation and
switch off the heater if the air temperature exceeds certain default safety limits: 38°C
(100.4°F) for control temperatures below 37°C (98.6°F) and 40°C (104.0°F) for control
temperatures above 37°C.
