Haven't looked at the CAA algorithm, here's what I use
Agreement and harmony breaking out all over the place, Gingernut ! Must be the influence of the festive season !
NICE defines hypertension as BP consistently over 140/90, which is
exactly the level specified in the CAA's algorithm ! (ie the level below which all is considered to be well ). In the CAA scheme of things there is then a "needs further consideration" interval, up to 160/95. If either figure is above those, then grounding ensues (albeit maybe only temporarily).
