if the purge does not sufficiently clear the flow tubing lines, the flow sensor should be replaced • with each purge cycle, a zero calibration is automatically performed 228 manual purging 15 monitoring airway flow, volume and pressure adult mode the system automatically purges the sensor tubing every ten minutes or less, depending on system conditions. in adult mode, the system will purge both sides of the line, one at a time, during each purge cycle. the higher the pressure, the more frequent the purging. this action anticipates increased moisture migration into the sensor tubing due to the increase in circuit pressure. neonatal and pediatric modes the automatic purge cycles used in the neonatal or pediatric mode is fixed at every three minutes regardless of circuit pressure. only one side of the sensor tubing will be purged during each purge cycle. unlike the adult purge mode, the neonatal or pediatric purge mode does not use the full force of the internal pump, but rather pressurizes an internal reservoir which is used for the purge. this minimizes the pressure delivered to the ventilator circuit, but does deliver a sufficient pressure to purge the sensor tubing. manual purging occasionally, purging may be required in between the automatic purge cycles. the manual purge may be used as often as needed. check the orientation of the flow sensor if repeated manual purge cycles become necessary. to manually purge, press the purge button on the module ( marked by rs on international versions of the module ) or select purge in the setup spirometry window to initiate a combined purge and zero cycle. gas compensation temperature and the proportions of individual gases influence the flow measurement. if values seem inaccurately high or low, check that the monitor is using the appropriate gas compensation. gas compensation can be done using either manually entered gas concentrations or gas concentrations from the gas analyzer. note if you unintent @topic:17

data flow from the host monitor to an x2 ( for example to feed data to a recorder module ). philips clinical network the monitoring system may be connected to the philips clinical network, for example to provide central monitoring capabilities or other network services. this connection may be through a normal wired connection. after configuration, the monitoring system sends the digitized patient signals including wave data, numerical data and status information onto the network. control data representing user interactions can be exchanged between the monitoring system and a central station bi - directionally. for plug and play operation, the monitoring system uses the standard bootp protocol to automatically acquire a network address. 21 how does the support tool work with the monitor the support tool is a windows application typically installed on the laptop of a customer engineer or a biomedical engineer working in the customer ’ s own service department. the purpose of the support tool is to upgrade, configure and diagnose all monitoring components in the system over the network. the service protocol developed for this purpose uses a raw access to the devices without the need for ip addresses etc. over a standard customer network installation, so that even defective devices can be upgraded as long as the few kbytes of initial boot code are working. the boot code itself can also be upgraded using the same protocol. the tool allows access to internal service information and to serial numbers. it can be remote - controlled, for example via a dial - up connection from a response center, provided the proper infrastructure 1s in place. for details see the instructions for use for the support tool. monitor software block diagram the figure below shows the functional block diagram for the monitoring system. a legend explaining terms and diagram elements follows. the information below varies depending on the purchased monitor options. philips clinical visual audio input devices network indicators indicators | | ecg sync pa lun ; interfaces functional block diagram 22 monitor theory of operation 2 theory of operation block diagram @topic:10
