General Information
CI.31.151
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.
CI.31.152
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.
1-10
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.
6600-0354-000 102
CI.31.148
CAUTION
CI.31.147
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.
