1. Tej ntshav siab
Cov neeg laus ib txwm muaj ntshav siab nyob ruaj khov thaum so, nrog ib txwm systolic ntshav siab ntawm 90 ～ 139mmHg, diastolic ntshav siab ntawm 60 ～ 89mmHg, thiab cov mem tes siab ntawm 30 ～ 40mmHg. Qhov txiaj ntsig ntawm ntshav siab rau menyuam yaus ntawm cov hnub nyoog sib txawv yog systolic ntshav siab (mmHg) = hnub nyoog × 2 + 80; diastolic ntshav siab = systolic ntshav siab × 2/3.
2. Mob ntshav siab
(1) Tshaj Tawm: Ntawm qhov tseeb tias tsis muaj cov tshuaj antihypertensive siv nyob rau hauv sphygmomanometer, systolic ntshav siab ≥140mmHg thiab / lossis diastolic ntshav siab ≥90mmHg rau cov neeg laus tshaj 18 xyoo.
(2) Hypotension: ntshav siab yog qis dua 90 / 60mmHg.
