When using the SN data type, what kind of values can be expressed?

The SN data type is designed to represent a "Structured Numeric" value, which includes not only simple numeric values but also qualified ranges of values. This means that the SN data type can express a number within a specific context that adds additional meaning to the numerical representation. For example, it can represent a range of values such as "100-120 mmHg" for blood pressure measurements, thus allowing for a more nuanced and detailed representation of numerical data in health-related situations.

The capacity to include qualified ranges is particularly important in healthcare, where understanding ranges can be critical for clinical decision-making. It allows practitioners to communicate a range of acceptable values, rather than a single discrete number, thereby providing a more comprehensive view of a patient's condition or a measurement. This feature of the SN data type enhances interoperability and the sharing of detailed clinical information among healthcare systems and professionals.
