Offsetable

An offsetable field can be filtered for a specific period of time, where 0 is the first second of ICU stay.

Offset Types

• After Admission
• After (>=)
• Before (<)
• Between (>= X and < Y)

Offset Value

The offset value can be one of the following:

• A number (time in seconds from ICU admission)
• A number and a time identifier, like "d" (days) or "h" (hours)
  • "3d" will be the first second of the third day
• A field identifier, an "f" followed by field index
  • f2 will be the third field of query
  • (this is used to define a timespan after a offset, like last laboratory before first erythrozyte application)
