#  
# This is an example of a cancelled standard blood pressure measurement. with an Observation/component/dataAbsentReason valued due to cancellation.
#
# Blood Pressure is a regarded as a single observation, and
# presented that way in plain text: 120/80. Also, it is usually
# interpreted as a single value, though intepretation can also
# be offered to the parts individually
#
# Technically, though, a blood pressure is a pair of component
# observations. LOINC code 85354-9 notes say:
#   This term is intended as a section header for various
#   blood pressure measurements (e.g. systolic, diastolic).
#   LOINC discourages the reporting of two numbers, such as
#   systolic and diastolic blood pressure (e.g. 120/80),
#   in one observation. They should be reported as two
#   separate variables, systolic (LOINC 8480-6) and
#   diastolic (LOINC 8462-4)
#
# This example shows the standard way to represent a meaurement that cause the expected values to be empty
# single resource, with a narrative in the standard form, and two
# component observations for the actual values with Observation/component/dataAbsentReason valued due to cancellation
