23 Communication with the Device Troubleshooting While TRENDset searches for a device, the following system messages can appear: System message No Connection to Therapy Device. The COM Port x is invalid or is used by another application. No connection to therapy device at the COM Port x. Cause A wrong COM-Port was selected. The COM-Port is either unavailable or blocked by another application. The device is not turned on. The serial cable is not properly connected with the computer or the device. The device is connected with another COM-Port. No device is connected. 23

24 Communication with the Device Read Device Data Select Communication > Read Device Data. You will have the option of three sub-menus: Read Device Memory Read Device Parameters Read Patient Data (if supported) Read Device Memory Select Communication > Read Device Data > Read Device Memory. The device memory consists, depending on device type, of a therapy memory and a compliance memory. The therapy memory contains all therapy data. In the compliance memory, only data on the use of the device are saved. You find the therapy data in the function areas Therapy Calendar, Data and Events as well as their statistical evaluation are found in Statistics. The use of the device will displayed in the Therapy Calendar. In these function areas you will find the imported therapy data. 24

25 Communication with the Device Reading the Device Parameters Select Communication > Read Device Data > Read Device Paramaters. The device parameters are displayed in the function areas Patient Data, Device Settings as well as Times and Counters. In these function areas you will find the imported device parameters. Reading Patient Data Select Communication > Read Device Data > Read Patient data. Patient data are imported and displayed in the function area Patient data. In this function area you will find the imported patient data. 25

26 Communication with the Device Delete Device Data Select Communication > Delete Device Data. You will have the option of four sub-menus: Delete Patient Data Delete Device Memory and Send Factory Settings Delete Device Memory Delete Factory Settings NOTE: The menu item Delete Device Data will only be displayed when a device is recognized and TRENDset is in Online status. Delete Patient Data Select Communication > Delete Device Data > Delete Patient Data. Delete Device Memory and Send Factory Settings Select Communication > Delete Device Data > Delete Device Memory and Send Factory Settings. This function is to be used if you wish to restore the factory settings on the device and delete the device s memory. WARNING! The deletion process lasts depending on device type up to 60 sec. The device may not be disconnected from the computer or the power supply during this time. 26

27 Communication with the Device Delete Device Memory Select Communication > Delete Device Data > Delete Device Memory. The entire therapy memory, with all pressure and flow values and the related events, will be deleted along with the compliance memory with the data on device use. NOTE: Before each action, you will be asked if the command should actually be executed. Send Factory Settings Select Communication > Delete Device Data > Send Factory Settings. All parameters and properties of the device will be restored to their factory-standard values. Additionally, all patient data will be deleted. 27

28 Communication with the Device Use of the DATA box The DATA box can store additional data such as oxygen partial pressure and pulse frequency. These data are shown as a curve diagram in the function area Data and Events. The data can be read from an SD-Card on your computer and evaluated. You will need a card reader device on your computer for this. NOTE: Before an SD-Card can be used for the DATA box, it must be formatted with TRENDset. DATA box 28

29 Communication with the Device Read SD-Card Select DATAbox > Read SD-Card. The dialogue box Read SD-Card will display the patient data that are saved on the SD-Card. Multiple patient data can be saved on an SD-Card. Activate a check box. Click on OK. The patient data are imported and displayed in TRENDset. TRENDset will switch to DATA box status. You can now change parameters in the function areas Device Settings or Patient Data and save on the SD-Card via Send. To load the files into the device, connect the DATA box to the device and then plug the SD-Card into the DATA box. 29

30 Communication with the Device Format SD-Card Before an SD-Card can be used with a DATA box, it must be formatted with TRENDset. It is irrelevant whether this is a new or used SD-Card. Not only the data storage medium is formatted, but DATA box-compatible properties are written onto the card. Select DATAbox > Format SD-Card. The dialogue box Format SD-Card will open and will list all removable disks for your computer. Select the data storage device by activating the check box. To prevent accidental erasures of files on the other removable disks, it will check whether there are still files on the selected drive. If yes, you will be prompted to deleted these files manually. NOTE: The SD-Card will not be accepted by the DATA box unless it is formatted with TRENDset. 30

31 Communication with the Device Save Data from SD-Cards All of a patient s data can be saved on the hard drive. Read the data from the SD-Card (DATAbox > Read SD-Card). Then save the file (File > Save/Save as). Files from the SD-Card will be stored with the extension.csa. Unlike other TRENDset-files (*.csw) files from an SD-Card have the extension.csa. These file are saved in the sub-directory DATAboxArchive. Open Data from SD-Cards Select File > Open or in the symbol bar. Before a new file is opened TRENDset checks whether all open files have been saved. As soon as a file is opened, TRENDset switches to the DATA box archive status. In this status you cannot store any patient data or change parameters on the SD-Card. NOTE: Files from the SD-Card (*.csa ) contain patient data that were saved by a DATA box. These files are often much larger than files with the extension.csw. 31

32 Communication with the Device Information about TRENDset Select? > About. The version number of TRENDset will be displayed along with information about the manufacturer. Using Help Select? > Help TRENDset. The Help file will open in PDF-Format. Help opens immediately if you press F1. NOTE: Help opens with Acrobat Reader.

In a leakage, i.e. if the mask slips out of face, the flow will increase. The relative volume of breath is calculated from the breath-flow. Average oxygen saturation Patient s current pulse A central apnea is indicated if, in addition to a limitation of airflow, no or little change in breath-flow or a simultaneous airway constriction is detected for more than 5 sec. An obstructive apnea is indicated if in addition to a limitation of airflow, little or no change in airflow is detected for at least 5 s and at the same time, airway constriction lying over a threshold value is detected. A mixed apnea is indicated if the apnea consists of a central and an obstruction portion and there is no normal breathing between the two portions. A hypopnea is indicated if an airflow limitation lasts for at least 5 sec. An airway constriction is indicated if the resistance of the upper airway stays above a threshold value for at least 3 sec. A snoring phase is indicated if snoring noises stay above a threshold value for at least 2 sec. 60
