General Information Incubator/Warmer operating modes
The Giraffe® OmniBed® combines the features of an incubator and a radiant warmer. When used as an incubator, a fan and heater beneath the bed circulate warm air through the closed infant compartment. The baby can be accessed through portholes or doors. When you require even greater access to the baby, the canopy can be raised and the compartment walls can be lowered. As the canopy raises, doors open to expose a focused radiant heating element inside the canopy that maintains the baby’s temperature like a warmer. The OmniBed allows the full range of clinical procedures without the disruptive intervention of transferring the baby from one care bed to another.
General Information Control Modes
1 10 9
Controls and Displays The controls and displays, located at the top of the uprights at the head of the bed, can be divided into two areas: on the left are the buttons and numeric temperature displays that control the temperature regulation of the infant, on the right are the graphics display screen and control knob that control all the accessory options. Temperatures can be shown in Celsius or Fahrenheit degrees: the default setting is Celsius.

Temperature Regulation At start up, the OmniBed prompts you to select one of the control modes. If the unit was used in the last 2 hours, it will ask if you would like to retain the settings you used previously. If you are using the OmniBed as an incubator (canopy closed)- you select baby or air mode. If you are using the OmniBed as a warmer (canopy open)- you select baby or manual mode. If you start with the canopy open, or open the bed during the first minutes after start up, and you do not select a control mode, the graphics screen will show the “Warm Up Mode” message and the radiant heater will automatically run at 100% power. When ten minutes has elapsed and you still have not selected a control mode, the graphics display will show the “Preheat Zone” message and the radiant heater will then run at the preheat level; the default preheat level setting is 25% power.
The OmniBed has two control modes when used as either an incubator or a warmer. With the compartment closed, the OmniBed controls the inside temperature comparing air temperature readings from the probe on the compartment wall to a setting you enter using the control panel (air mode) or from a probe attached to the baby’s skin (baby mode). With the canopy raised, the OmniBed controls radiant heater output from a heater power percentage setting that you enter using the control panel (manual mode) or by using temperature readings from a probe attached to the baby’s skin (baby mode).

General Information Operating Mode Transition If the canopy is raised while the OmniBed is being operated as an incubator, it automatically switches to operation as a radiant warmer. If it was in the baby mode as an incubator, after the canopy is raised it will continue to operate in the baby mode, using the same baby set temperature you entered earlier. If the canopy is raised while the OmniBed is being operated in the air mode as an incubator, it will operate in the manual mode as a warmer. The radiant heater will activate at the preheat level (the factory set preheat level is 25%; this can be adjusted on the service screen), and the OmniBed will prompt you to select a heater power percentage. If the canopy is lowered while the OmniBed is being operated as a radiant warmer, it automatically switches to operation as an incubator. If it was in the baby mode as a warmer, after the canopy is lowered it will continue to operate in the baby mode, using the same baby set temperature you entered earlier. If the canopy is lowered while the OmniBed is being operated in the manual mode as an warmer, it will operate in the air mode as an incubator. The compartment heater and fan will start at the last air set temperature saved since power-off, or at the preheat temperature of 33°C, and the OmniBed will prompt you to select an air set temperature.

The “Man Temp Alarm” can be used in either the warmer Manual mode or the incubator Air mode. However, to select a set temperature you must first select the Baby mode, input the set point, then select the Manual or Air modes. This optional alarm provides you audiovisual notification in the Air control mode if the skin probe temperature drifts outside the range you select. For example, if you select 0.5°C on the setup screen, and then set 36.5°C as the skin temperature threshold in the Baby mode before switching to the Air mode, the alarm will sound if the baby’s skin temperature falls below 36°C or rises above 37°C while in the Air mode. If this alarm is not required, or if the skin temperature probe is not being used, “Man Temp Alarm” should always be set to “Off” on the setup screen. Select “Patient Alarm” to choose between 2 settings: choose “.5” ” to set the alarm to activate when a 0.5°C difference is read between a set temperature and the baby probe temperature, or choose “1.0” to set the alarm to activate when a 1.0°C difference is read between a set temperature and the baby probe temperature.”1.0” is the default setting. The “Patient Alarm” is used in either the incubator or warmer Baby modes. Select “Canopy Pedal” to disable or enable foot pedals that raise the canopy. When the pedal is disabled, the canopy can still be raised or lowered with the buttons on either side at the head of the bed. Select “Set Clock” to change the time setting in hours, minutes and seconds on a 24 hour clock. Note: Early versions of the software have no “Set Clock” menu option on the set up screen. On these units the time must be set using the service screen. See the service manual on accessing the service screen. Select “Elevate” to disable or enable the foot pedals that raise or lower the bed height. Note: If the canopy or bed elevate pedals have been disabled on the service screen they cannot be enabled using the setup screen. Select “Baby Info” to bring up the Baby Info screen. By turning the knob until the desired character appears and then pushing the knob, you can enter up to a 9-character name. Blanks and periods can also be selected. Selecting “ ” allows you to go back and change the previous character. Selecting “ ” enters the letters you have selected for names that are less than 9 characters long. By selecting the month, day and year numbers, you can enter the baby’s birth date. These settings will be saved for 2 hours after power down. Select Done/Exit to return to the option icon screen. Note: A service screen allows you to change preheat % power, alarm criteria, disable the canopy control pedal and other default settings. See the service manual for a description of this screen and how it may be accessed. Servo Control Oxygen System is a fully integrated option available on the Giraffe® OmniBed® During operation noise levels in the infant compartment are imperceptible. Remote oxygen sensors mount inside the unit underneath the bed. 1-9
Note: Calibration is required only if the Servo Control Oxygen System is activated. The Giraffe Servo Control Oxygen System uses fuel cell type sensors that generate specific voltages depending on the oxygen concentrations that are present. The microprocessor stores this measurement and compares it with the setting you enter using the display, opening and closing the valves that allow supply oxygen into the baby compartment. Fluctuations in fuel cell temperature and humidity are compensated for by the microprocessor. The temperature of the oxygen sensor housing under the bed is always slightly higher than the baby compartment, so condensation that would affect accuracy will not occur.
Oxygen concentration is set using the OmniBed’s or Incubator’s display. Calibration, prompted once a day by the display, requires only a single push of a button. The Servo Control Oxygen System allows the administration of oxygen with virtually no intrusion to either you or the baby.
The Servo control system should be calibrated before each patient and at least once during every 24 hours. The system must be connected to an oxygen source during calibration. The display will prompt you when the system requires calibration. Calibration is initiated from the Set Up (wrench icon) screen by selecting Cal Oxygen. Once you start it, calibration is automatic and takes less than five minutes. A bar graph indicates progress toward completing calibration. If for any reason you wish to discontinue calibration before it is completed, turning the control knob in either direction will cause the word Cancel to appear on the calibration screen. Pushing in the control knob will discontinue calibration. The servo-control system must be calibrated at the same atmospheric pressure in which it is to be used. Operation at atmospheric pressures other than that present during calibration may result in readings outside the stated accuracy for the unit. Scale: Available if the in-bed scale is installed. Select the Scale icon (balance scale) to bring up the scale menu screen. Select Weigh
Select the O2 icon to bring up the Servo Control Oxygen System screen. The actual concentration of oxygen, from the sensor underneath the compartment, is displayed in large numerals. The set percentage of oxygen by volume, ranging from 21 to 65%, is shown in smaller numerals. Adjust the set percentage to the desired level by pushing the knob to select the setting. Turn the knob to increase or decrease percentage then push the knob to enter the new setting. Exit the menu. The actual and set oxygen concentrations will remain displayed.
Note: A FiO2 > 26% message indicates a leak or higher oxygen levels from other equipment. For more information see Option Alarms later in this chapter.
Servo-Humidity: Select the Humidity icon to bring up the humidity menu screen. The actual relative humidity measured inside the infant compartment is displayed in large numerals. The set relative humidity is shown in smaller numerals. Adjust the relative humidity percentage to the desired level by pushing the knob to highlight the setting. Turn the knob to increase or decrease the humidity setting then push the knob to enter the new setting. Exit the menu. The actual and set relative humidity will remain displayed. To deactivate the humidifier, set the humidity level to “off”.
to start the weighing procedure. An audio prompt sounds and the screen will prompt you to lift the baby from the bed surface while the scale zeros. It then tells you to replace the baby on the bed and calculates the infant’s weight. Select Trend to plot a series of weights on a graph. Select Modify to change to smaller increments on the Y axis, and so enlarge the differences shown between weights plotted on the graph. The axis will automatically adjust to the nearest 500 gram threshold base. Select Done/Exit to return to the option icon screen.
General Information 1 2
An alarm message appears across the top graphics display screen identifying the various alarm conditions. In addition, the alarm light at the top of the control panel housing activates and an audio alarm sounds.
With the exception of the system failure and power failure alarms, all audio alarms can be silenced by pressing the alarm silence button located above the graphics screen. At the end of the alarm silence period the alarm reactivates if the alarm condition has not been resolved. If two or more alarm conditions occur at the same time, the audio signal for the highest priority alarm will sound while all the alarm messages will alternately appear at the top of the graphics screen. If you select the Help icon during an alarm condition, the description of that particular alarm will automatically appear on the screen.
The audio tone varies with the alarm’s priority: an alternating two tone alarm indicates a critical alarm that triggers automatic heater shutdown; an intermittent single tone alarm is used for other alarms. The alarm light remains on continuously for over temperature and system failure alarms; it blinks for all other alarms.

These alarms warn of abnormally high temperatures read by the compartment probe in all control modes and automatically shut off the heater. They are not self resetting; once the alarms are activated they must be manually reset by pushing the alarm silence button, even if the alarm condition is resolved. Computer independent circuitry continuously measures and compares the compartment temperature with factory set levels. Visual and audible alarms are activated and the heater shuts off if the compartment temperature exceeds these preset levels, independent of the software. The functionality of all other alarms is continually checked by the microprocessor software during normal operation. If a fault occurs in any of this circuitry, an indicator lights and a tone is sounded. Additionally, a computer independent “watchdog” circuit will reset the computer, turn off the heater, and activate the alarms in the event of a microprocessor failure or software error.
Active only when the canopy is closed and the set temperature is below 37°C, the Air Temp >38°C alarm activates in the air mode when temperatures greater than 38°C are read by the compartment probe.

General Information Disconnect Probe 2 for Baby Mode CI.31.184
This alarm activates when either the Giraffe is in the Baby Mode and a probe is inserted in Jack 2 on the probe panel, or when the Giraffe has 2 probes connected and the Baby Mode button is pushed. If the Giraffe is in the Baby Mode and a probe is inserted in Jack 2, the Giraffe will automatically switch to the Air Mode (if the canopy is open, the OmniBed will automatically switch to the Manual mode). To deactivate the alarm, remove probe from Jack 2. Note: the unit will continue to operate in the Air or Manual Mode until the Baby Mode button is pressed. If the Giraffe is in the Air Mode (Manual Mode on the OmniBed) with probes in Jack 1 & 2, and the Baby Mode button is pressed, you can deactivate the alarm by pushing the alarm silence button.
Temperature Out of Calibration
This alarm activates if there is a temperature calibration error while turning on the unit; the unit will now use a default value to control temperature. Pressing the alarm silence will cancel the audio alarm, but the Temperature Out of Calibration message will remain on the display. You can continue to use the OmniBed while a baby occupies the bed, but the unit should be serviced before using it with another patient.
System Failure Do not use the OmniBed if the system failure alarm is activated. Remove the unit from service and refer to qualified personnel for repair.
If an electrical failure is detected, the system failure alarm automatically shuts off the heater and triggers a two tone audio alarm that can not be silenced.
Bad Membrane Switch One of the electronic switches behind the control panel buttons has failed. This alarm can not be silenced. Remove unit from service.
Power Failure If power to the unit is cut off, an audio alarm sounds and a LED lights.
The following alarm messages indicate a repair is required, but the OmniBed can be used in another operating mode, the unit need not be taken immediately out of service.
