1、1OpenSpirometry Draft Software Specification Please send reviews and comments to David Van Sickle () and the OpenSpirometry team ( )Revision historyRevisionDescriptionDate 1.0First draftJune 23, 2009Overview This client software application has three major goals: 1) Acquire, analyze, graph and store
2、 data from a spirometer connected to the computer via USB; 2) Deliver embedded training and instruction to users and technicians; and 3) Ensure quality measurements by evaluating maneuvers in real-time and delivering appropriate coaching and audiovisual incentives. The program will utilize a freely
3、available platform such as Adobe AIR to enable it to be operated on any major operating system. Terminology For the purposes of this document, the following terms will be used: Maneuver the standard procedure that the subject follows to generate the spirometry results Trial the performance of one in
4、dividual forced expiratory maneuver and the associated calculations specific to only that current maneuver Test a set of acceptable trials and the calculations that utilize the set as a wholeRequirements and SpecificationsPlug and Play should detect spirometer is connected Communication with iLite (
5、see Appendix A). The application should be able to read data and to write coefficients when using Calibration mode with the 3-L syringe. During maneuvers, spirometer will output data via USB 2.0.Data will contain temperature, flow and volume data and be sent at known sample rate. This data will be u
6、sed in calculations and displays as described below.During a maneuver, all data should be displayed in real-time.Video playback capability (format) must also be supported.The database will be storing confidential patient data. This data must be password protected whenever data can be linked to speci
7、fic patients. If appropriate, the data should also be encrypted when transmitted over a network.23Graphical User Interface (GUI) *NOTE Items in Blue indicate options we would like to see in that screens menu. *Items in Green are questions that are related to spirometry and will need to be discussed
8、with individuals knowledgable about practicing and recording spirometry tests.Overall Style should utilize friendly, light colors for boxes and displays. The software should have the capacity to be localizable (multilingual).Opening Menu Select User type: Technician or Home User HelpAbout Main Menu
9、options If Technician is selected The technician must enter in their ID number and password for access. Once authorized, the technician should remain logged in until they click to log out. oThe log out option should be available on the Technician Main Menu Testing data must indicate which technician
