condition. the record service can also send data to a recorder. 25 [ 2 theory of operation ] functional block description alarm the alarm service contains logic that prioritizes alarm conditions that are generated either by the measurement servers or by intellivue patient monitoring system software modules. visual alarm signals ( messages ) are displayed at the top of the intellivue patient monitoring system display and alarm sounds are generated by a loudspeaker. alarm conditions may be generated when a physiological parameter exceeds preselected alarm limits or when a physiological parameter or any other software module reports an inoperative status ( technical alarm, for example, the egg leads may have fallen off the patient ). the alarm service manages the alarm inactivation states, for example suspension of alarms, silencing of alarms, and alarm reminder. alarm signals may also be configured as latching ( alarm signals are issued until they are acknowledged by the operator, even when the alarm condition is no longer true ). the alarm service controls the visual alarm signals ( alarm lamps ). trend the trend service stores the sample values of physiological data and status data with a resolution of 12 seconds, 1 minute or 5 minutes for a period of up to 48 hours. the data is kept in battery buffered read / write storage and flash memory devices to be preserved across power failures. the stored data is protected via consistency checks and checksums. when a new patient is admitted, the trend database erases all data of the previous patient. oxycrg the oxycrg ( oxygen cardiorespirogram ) service derives a high - resolution trend graph from the beat - to - beat heart rate, sp02 or tcp02, and respiration physiological data. the oxycrg is specialized for neonatal applications, allowing the operator to identify sudden drops in heart rate ( bradycardia ) and sp02 or tc @topic:8
