"normal" is relative
The 7th joint national commission still says 120/80 with a "pre-hypertensive" range that's a bit higher. "normal" bps are variable, so how checked is important.
Put arm cuff (not wrist or finger) on, sit quietly for few minutes, no food, alcohol
. Auto-inflated cuffs better. Manual readings may yield spuriously low bps if released too rapidly. Consider 24h monitor if still high.
