Monitor is a MacOS Automated Anaesthetic Record Keeping system (AARK). It allows you to plot data downloaded from anaesthetic monitors, as well as enter data for drugs, fluids, procedures, urine output, blood loss, positioning, cardiac rhythm and other events. Unlike most other AARKs, Monitor stores all transmitted data at full resolution, which is usually between 2 and 10 seconds. You can automatically save data as a pdf file to a remote server, as well as print out an anaesthetic record. Records can be customised, and it is possible to have different records for different functions in an institution. NOTE you will need to readjust your preferences after installing 2.1, as the prefs files are not completely compatible with 2.0
