A Explanation of Patient Orientation (Normative)
ThisAnnexwasformerlylocatedinAnnexE“ExplanationofPatientOrientation(Normative)”inPS3.3inthe2003andearlierrevisions
of the Standard.
This Annex provides an explanation of how to use the patient orientation data elements.
Head (H)
Right (R)
Posterior (P)
Anterior (A)
Left (L)
Foot (F)
The standard anatomic position is standing erect with the palms facing anterior. This position is used to define a label for the direction of the fingers and toes (toward the Feet (F) while the direction of the wrist and ankle is towards the Head (H). This labeling is retained despite changes in the position of the extremities. For bilaterally symmetric body parts, a laterality indicator (R or L) should be used.

For the hands, the direction labels are based on the standard |

anatomic position. For the left hand illustrated for example, |
|
LEFT will always be in the direction of the thumb, irrespective |

of position changes. |

As for the hand, the direction labels are based on the foot in the standard anatomic position. For the right foot, for example, RIGHT will be in the direction of the 5th toe. This assignment will remain constant through movement or positioning of the extremity. This is also true of the HEAD and FOOT directions.

As for the hand, the direction labels are based on the foot in the standard anatomic position. For the right foot, for example, RIGHT will be in the direction of the 5th toe. This assignment will remain constant through movement or positioning of the extremity. This is also true of the HEAD and FOOT directions.
