1. Blood pressure: 120/80 mmHg. This is the normal blood pressure range, indicating that the measurement results are standard blood pressure.

2. Blood pressure: 135/95 mmHg. This indicates that both systolic and diastolic blood pressure are slightly high, and attention should be paid to maintaining a healthy lifestyle.

3. Blood pressure: 150/100 mmHg. This indicates that both systolic and diastolic blood pressure are high, and measures should be taken to control blood pressure, such as adjusting diet, increasing exercise, or using antihypertensive drugs. Changes in blood pressure should be monitored regularly.
