**Observation Body Position**: Sitting position (finding)

**status**: Final

**category**: Vital Signs

**code**: Hemoglobin [Mass/volume] in Venous blood

**subject**: [Jim Chalmers Male, DoB: 1974-12-25 ( Social Security number (use: usual, period: 2001-05-06 --> (ongoing)))](Patient-example.md)

**encounter**: [Encounter: identifier = http://example.org/encounters#ENC-20130404-appendicitis; status = finished; class = inpatient encounter (v3 Code System ActCode#IMP); type = Initial hospital inpatient or observation care, per day, for the evaluation and management of a patient, which requires a medically appropriate history and/or examination and high level of medical decision making. When using total time on the date of the encounter for code selection, 75 minutes must be met or exceeded.; period = 2013-04-04 18:00:00-0400 --> 2013-04-06 11:00:00-0400](Encounter-example.md)
