Q

When might standing blood pressure be used?

A

Take after standing for one minute, then against after standing for three minutes
Normally expect to decrease originally then stabilise or increase towards original
- taken for concerns over orthostatic hypertension, elevated blood pressure when standing may indicate an increased risk of heart attack.

A

Mark on systolic and diastolic - join with a line
