resulting alarm delay this diagram shows the area for short mode, with two examples of hypoxia. progressive hypoxia scenario : spo2 value ( a ) - the values drop steadily and after 10 seconds a value leaves the shaded area. an alarm is indicated immediately. recovery scenario : spo2 value ( b ) - the values stay within the shaded area for 24 seconds, deviating from the alarm limit by 1 % or 2 %, before rising again above the alarm limit. no alarm is indicated because the spo2 values never leave the shaded area below the alarm limit. on the basis of the two examples, you can see that the delay depends on how much the value exceeds the limit, and for how long. changes in the spo2 value can be major, but very short, or minor and for longer time as long as they stay within the shaded area there will be no alarm indicated. 97 9 monitoring spo2 alarm limit 1 % 2 % 3 % - deviation from 4 % violated alarm 5 % - limit 6 % 7 % - 8 % 9 % - 10 % - 10s os 20s 50s 40s 30s resulting alarm delay this diagram shows the area for medium mode, with two examples of hypoxia. progressive hypoxia scenario : spo2 value ( c ) - the values drop steadily and after 11 seconds a value leaves the shaded area. an alarm is indicated immediately. recovery scenario : spo2 value ( d ) - the values stay within the shaded area for 48 seconds, deviating from the alarm limit by 1 % or 2 %, before rising again above the alarm limit. no alarm is indicated because the spo2 values never leave the shaded area below the alarm limit. alarm limit 1 % 2 % - 3 % deviation from 4 % violated alarm 5 % - limit 6 % - 7 % - 8 % 9 % 10 @topic:17

2 theory of operation ) persistent data storage system service some applications require storage of data over longer periods of time. they can use the persistent data storage system service. dependent on the application requirements, this service can store data either in battery backed - up ( buffered ) memory or in flash memory. the buffered memory will lose its contents if the monitor is without power ( not connected to mains ) for an extended period of time. the flash memory does not lose its contents. the trend application for example stores vital signs data in a combination of flash memory and buffered memory, while the system conflguration information ( profiles ) is kept purely in flash memory. display and user interface service applications can use high level commands to display monitoring data or status and command windows on the internal lcd panel. these commands are interpreted by the display manager application. this application controls the dedicated video hardware. user input is acquired from a variety of input devices, for example the touchscreen or other standard input devices ( keyboard, mouse ). the system software makes sure that the user input is directed to the application which has the operating focus. data output the monitoring system is very flexible and customizable regarding its data output devices. built - in devices ( for example lan, video ) provide the basic output capabilities. these capabilities can be enhanced by adding additional i / o boards, as required in the specific end - user setup. the additional i / o boards typically provide data to externally attached devices, for example to rs232 based data collection devices. the monitor can identify i / o boards by means of a serial eeprom device that stores type and version information. the operating system detects the i / o boards and automatically connects them with the associated ( interface driver ) application. for some multi - purpose boards it is necessary to configure the board for a particular purpose first ( for example the mib / rs @topic:10
