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 alarm criteria and other default settings. See the service manual for a description of this screen and how it may be accessed. 1-9
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. 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.
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. 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. 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.
w 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.
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.
Scale: Available if the in-bed scale is installed. Select the Scale icon (balance scale) to bring up the scale menu screen. Select Weigh 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. Select Done/Exit to return to the option icon screen.
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”.
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.

General Information Baby Hot - Check Probe 1
Active whenever the unit is in the baby mode, the Baby Hot alarm activates when the temperature measured by the probe on the baby skin is 1.0°C above the baby temperature you set previously (this can be adjusted to 0.5°C using the Setup/ Customize screen). Monitor the patient carefully and check the attachment of the probe on the baby’s skin. The audio alarm is suspended for a ten minute period when you push the alarm silence button. This alarm can also be activated in the Air mode. See setup screen.
Baby Cold - Check Probe 1
Active whenever the unit is in the baby mode, the Baby Cold alarm activates when the temperature measured by the probe on the baby skin is 1.0°C below the baby temperature you set previously (this can be adjusted to 0.5°C using the Setup/ Customize screen). Monitor the patient carefully and check the attachment of the probe on the baby’s skin. The audio alarm is suspended for a ten minute period when you push the alarm silence button. This alarm can also be activated in the Air mode. See setup screen.
Air Temperature Greater Than... 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.
Air Temperature >38 C
Active only when 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. This alarm may occur when you have just lowered the air set temperature, or when you have changed from baby to air control mode. Monitor the unit closely to assure the air temperature decreases.
General Information Air Temperature > 40 C In the air mode, when the air temperature is set above 37°C by using the >37°C key, the Air Temp >40°C alarm activates when temperatures greater than 40°C are read by the compartment probe.
In the baby mode, the Air Temp >40°C alarm activates whenever temperatures greater than 40°C are read by the compartment probe. Check for external heat sources on the baby (sunlight, phototherapy lamp, etc.)
Disconnected Baby Probe 1
Active in both modes, the Disconnected Baby Probe alarm activates when the baby skin probe jack is unplugged at the jack panel. Check that jack is fully inserted. Check that the Man Temp Alarm has not been set in error.
