| Blood Pressure Classification | Systolic Blood Pressure (SBP) mmHg |
Diastolic Blood Pressure (DBP) mmHg |
Health Risk Tips |
|---|---|---|---|
| Ideal Normal Blood Pressure | ＜120 | ＜80 | Low vascular load, extremely low cardiovascular risk |
| High Normal (Borderline High) |
120～139 | 80～89 | Sub-health warning, adjust work and rest and diet to prevent hypertension |
| Grade 1 Hypertension (Mild) |
140～159 | 90～99 | Mildly elevated, improve lifestyle, continuous monitoring and review |
| Grade 2 Hypertension (Moderate) |
160～179 | 100～109 | Increased risk of cardiac, renal and vascular damage, medical examination recommended |
| Grade 3 Hypertension (Severe) |
≥180 | ≥110 | High risk! Prone to cerebral infarction, cerebral hemorrhage, heart failure, seek medical attention as soon as possible |
| Low Blood Pressure | ＜90 | ＜60 | Prone to dizziness, fatigue, postural vertigo; physical weakness/dehydration needs conditioning |
Systolic BP ≥140mmHg, Diastolic BP ＜90mmHg → Belongs to hypertension category, typical manifestation of arteriosclerosis in middle-aged and elderly people
1. Photoplethysmography (PPG) blood pressure measurement by bracelet ≠ medical mercury/electronic arm-type sphygmomanometer; the value is only for trend reference and cannot be used as a diagnosis basis;
2. Measurement specifications: Rest quietly for 5 minutes, keep arm at heart level, do not speak; take the average value at the same time period for 3 consecutive days;
3. If Grade 2 or 3 hypertension persists for multiple measurements, be sure to confirm the diagnosis in the cardiology department of a hospital.
