Data element attributes
Collection and usage attributes
|Guide for use:||For recording the systolic reading, use phase I Korotkoff (the first appearance of sound). If Blood pressure - systolic is not collected or not able to be collected, code 999.|
Measurement protocol for resting blood pressure:
The systolic blood pressure is one component of a routine blood pressure measurement (i.e. systolic/diastolic) and reflects the maximum pressure to which the arteries are exposed.
The pressure head is the height difference a pressure can raise a fluid's equilibrium level above the surface subjected to pressure. (Blood pressure is usually measured as a head of Mercury, and this is the unit of measure nominated for this metadata item.)
The current (2002) definition of hypertension is based on the level of blood pressure above which treatment is recommended, and this depends on the presence of other risk factors, e.g. age, diabetes etc. (NHF 1999 Guide to Management of Hypertension).
