- Systolic Blood Pressure (SBP)

Blood pressure when the heart contracts.
When this value is 135 or more is called "High Blood Pressure".
Unit: mmHg

- Diastolic Blood Pressure (DBP)

Blood pressure when the heart expands.
When this value is 85 or more is called "High Blood Pressure".
Unit: mmHg

- Pulse (P)

Periodic beat that is transmitted to the artery every time the heart contracts and blood is pushed out.
When this value is less than 60 is called "Bradycardia", 101 or more is called "Tachycardia".
Unit: bpm

- Mean Blood Pressure (MBP)

An indicator to judge the risk of arteriosclerosis of a blood vessel distant from the heart.
It is desirable to keep this value within 100.
Unit: mmHg
Formula: (SBP+DBP+DBP)/3

- Pulse Pressure (PP)

An indicator to judge the risk of arteriosclerosis of a blood vessel near the heart.
It is desirable to keep this value within 40-60.
Unit: mmHg
Formula: SBP-DBP

- Morning Blood Pressure

Blood pressure measured within 1 hour after getting up.

- Evening Blood Pressure

Blood pressure measured before going to bed.

- ME Difference (Morning-Evening Difference, ME Diff)

An indicator to judge the risk of stroke or heart disease by the difference between morning and evening blood pressure.
It is desirable to keep this value below 15.
Unit: mmHg
Formula: (SBP of Morning BP)-(SBP of Evening BP)

- ME Average (Morning-Evening Average, ME Ave)

An indicator to judge the risk of stroke or heart disease by the difference (average) between morning and evening blood pressure.
It is desirable to keep this value below 135.
Unit: mmHg
Formula: ((SBP of Morning BP)+(SBP of Evening BP))/2
