Next, the Treatment Display section is used to access and set all parameters. It is organized into three subsections which are the treatment display screen, the screen access buttons, and the data entry keys. The treatment screen display contains the area for viewing the various treatment screens. The screen access buttons below the display area are used to access the various treatment screens. The data entry keys, at the bottom of the treatment display section, are the the menus used to enter treatment parameter values or make selections inside the treatment screen. The function of the home key is to view current treatment data including treatment time remaining, UF data, arterial, venous, and transmembrane pressures, and dialysate data. The trends key is to view charts that provide graphic views of treatment effectiveness (Kt/V), sodium variation system (SVS) and ultra filtration (UF) profiles, and patient’s blood pressure over time. The dialysate key is to view and select acid/bicarbonate concentrate type, bicarbonate, sodium, electrolyte concentrations, and conductivity settings. Test and options key is to view pressure test, Alarm test, and diasafe test options and results. Besides, it view treatment options for pediatric and single needle patients, high flux dialyzers, patient ID numbers, and dialysate sampling. The heparin key is to view options for administering heparin gradually over the course of the treatment or as a bolus injection. Next, the Kt/V AF key is to view estimate of treatment effectiveness based on the actual dialyzer clearance and view the access flow messages and data. BTM/BVM key is to view arterial and venous blood temperature data with machines equipped with the optional Blood temperature Module and view the relative blood volume data and trends with machines equipped with the optional Blood Volume Module. The Blood Pressure key is to view all pulse and blood pressure test results taken during treatment Blood pressure alarm limits and inflation pressure and frequency of blood pressure tests are set in this screen. 1,2,3 keys are to enter numerical values when setting parameters for such treatment options as ultrafiltration rate, times, goal, and volumes. Up arrow and down arrow keys are to scroll up or down a list of parameter choices or to increase or decrease parameter values and to speed up the rate at which the value changes, press and hold the key down. Confirm key is to save a treatment parameter entry or confirm an action initiated on the touch screen. The confirm key is also a backup, safety feature designed to prevent accidental changes to the intended treatment parameters. Escape key is to void the current entry and return to previously entered parameter value before confirm is pressed.
