Abstract: To provide accurate reconstructable records of the events and therapy administered during a cardiac arrest, flow sheets are attached to the top of a timing clipboard. Each row of the flow sheet matrix indicates a different event and the columns indicate the time of events. The clipboard illuminates columns at intervals in the range of fifteen seconds to five minutes in a timed sequence across the flow sheet by energizing electroluminescent trips underneath the flow sheet to permit the nurse to indicate the events in the column corresponding to the time of the event. Other sensed data is recorded on a tape with timing signals for later reconstruction. When all of the columns have been covered, an alarm is sounded so that a new flow sheet may be attached. The page of the flow sheet is indicated on the clipboard for translation onto the flow sheet.
