Handling vital-signs
FHIR defines vital-signs as:
Clinical observations measure the body's basic functions such as blood pressure, heart rate, respiratory rate, height, weight, body mass index, head circumference, pulse oximetry, temperature, and body surface area.
While the provider should make every effort to ensure they are providing accurate information, there are certain conventions that are preferred within GP practice which are shown hin the table below.
Note: It is preferred that the value displayed to the user is rounded up if displaying to a decimal place that is less than the recorded value.
Conventions
All units of measure use the Value set: UCUM for vital-signs.
