Care Plus Humidier provides an ecient supply of humidied air to help meet your
patient’s thermoregulatory needs by reducing convective and evaporative heat loss.
With a series of operator prompts, quiet operation, and an easily accessible humidier
ll tray, the Care Plus Servo-controlled humidier oers both security and convenience.
It easily integrates into the new or previous versions of the Care Plus. The familiar
control panel, similar in styling and function to the Care Plus Incubator, allows
easyselection of humidity levels.
The Care Plus Servo-controlled Humidier augments the thermal eciency of the Care
Plus incubator to stabilize patient temperature:
• Thecontrollerrespondsimmediatelytohumiditychanges,minimizingthehumidity

compartment reduces evaporative heat loss of the patient and helps to reduce
patient Insensible Water Loss (IWL).
WARNING Before using the Ohio Care Plus Servo-controlled Humidier accessory, read
through this entire manual. As with all medical equipment, attempting to use
this device without a thorough understanding of its operation may result
in patient or user injury. This device should only be operated by personnel
trained in its operation and under the direction of medical personnel familiar
with the risks and benets of this type of device.

Description
The Ohio Care Plus Servo-controlled Humidier uses a heating element in a water
tray under the incubator to provide humidication. An electronic controller adjacent
to the water tray uses a microprocessor to control the heating element. The heating
element produces warm water vapor and opens a valve that releases that vapor into
the incubator patient chamber.
The desired humidity level is entered on a control panel on the front of the humidier.
The controller compares relative humidity readings from a sensor located inside the
patient chamber of the incubator to this set humidity, and regulates the heater and
valve to maintain the desired humidity.

The humidier servo-control
The Care Plus Servo-controlled Humidier adjusts humidity output to achieve a
desired humidity level. The desired humidity level, which appears in the display on the
front of the humidier, can be adjusted using the humidity switches (?and M).
The controller compares the humidity display value to the control humidity setting. A
microprocessor regulates the heater, which adjusts the valve in the opening to provide
the desired humidity level.
Control Humidity Range
After you press the enable button, the controller lets you enter humidity control values
from 40 to 85% RH using the humidity switches ( ?and M).

Controls and Displays
RH Display
The humidity display shows the relative humidity inside the incubator chamber.
Relative humidity levels between 5 and 95% RH are displayed to an accuracy of
± 10% of the actual relative humidity at the center of the bed.
RH Control Setting
The control humidity display shows the control humidity selected by the operator.
When you rst power up the unit, the control display blinks until you enter a set point.
A ten segment lighted bar display shows the selected humidity level in 5% increments
of the 40 to 85% range.
The humidity switches (?and M) raise or lower the set humidity in 5% increments.
Pressing the Enable switch activates the humidity switches for approximately 15
seconds. The enable indicator lights when these switches are active. If the indicator
goes out, you must push it again to use the humidity switches.
The power On/O switch is located on the left side of the humidier controller, next
to the power cord socket. Two circuit fuses, located within the controller, limit the
maximum current drawn by the humidier. If the circuit fuses open, remove the unit
from use and contact qualied service personnel for repair.
Two lighted indicators on the left side of the control panel, Auto Shuto/Add Water and
System Fail, light for operator prompt conditions. In addition to the indicators, each
condition has an audible prompt tone.

Operator prompts
Silencing a prompt
The system failure prompt cannot be silenced. The low water level prompt can be
silenced by sliding out the humidier ll tray.
System fail
A system failure automatically shuts o the heater and triggers a continuous tone when
an electrical failure is detected. During a system failure, the system fail indicator lights
and a tone sounds. The following conditions trigger a system failure:
• Adisconnected,openorshortcircuitinthehumidiersensor.
• Anopencircuitontheheater.
• Acontrollermalfunction
Auto Shuto/Add Water
The Auto Shuto/Add Water prompt automatically shuts o the heater. These
conditions trigger a Auto Shuto/Add water prompt:
• Thewaterlevelislowinthehumidierlltray.Theprompttonecanbesilencedby
sliding out the ll tray, but the indicator stays lit and the RH display ashes. If there
is still no water in the tray when it is replaced, the prompt tone will start sounding
again within a few minutes.
• Thehumidierlltrayisnotfullyinserted.Onlytheindicatorwilllight;notonewill
sound. Power to the heater is disrupted until the tray is fully inserted.
Note: If the Auto Shuto/Add Water prompt sounds and the ll tray is removed and
then replaced without water in it, there is a 30 second delay before the prompt sounds
again.
Note: This is not an instantaneous prompt. There will be a delay of no more than
20 minutes before the prompt sounds even when the ll tray is dry.
