VSUSCHFL | Unscheduled Flag | Char | (NY) | Record Qualifier | Indicates whether the timing of the performed test or observation was unscheduled. If a test or observation was performed based upon a schedule defined in the protocol, this flag should be null. Expected values are Y or null. | Perm |
VISITDY | Planned Study Day of Collection | Num |
| Timing | Planned day of the vital signs measurement. Should be an integer. | Perm |
VSDTC | Date/Time of Measurement | Char | ISO 8601 datetime or interval | Timing | Date/Time of the vital sign measurement, in ISO 8601 format. For indicating measurement over a period, DTC should be populated with the start date/time of collection. | Exp |
VSENDTC | End Date/Time of Measurement | Char | ISO 8601 datetime or interval | Timing | Date/Time of the end of the vital sign measurement, in ISO 8601 format. Should be populated for continuous period only. | Perm |
VSDY | Study Day of Vital Signs Measurement | Num |

VSELTM | Planned Elapsed Time from Time Point Ref | Char | ISO 8601 duration duration | Timing | Planned elapsed time (in ISO 8601 format) relative to a planned fixed reference (VSTPTREF). This variable is useful where there are repetitive measures. Not a clock time or a date time variable. Represented as a duration in ISO 8601 format.
