Frequently Asked Questions

What is normal blood pressure?

Normal blood pressure is below 120/80 mmHg. Elevated is 120-129 systolic with diastolic under 80. Hypertension Stage 1 is 130-139/80-89, and Stage 2 is 140+/90+.

How can I lower my blood pressure naturally?

Reduce sodium intake, maintain healthy weight, exercise regularly (150 min/week), limit alcohol, manage stress, and get adequate sleep. The DASH diet is particularly effective.

What is a universal blood donor?

O-negative is the universal donor — it can be given to patients of any blood type. This makes it critical in emergencies when there is no time to test the recipient's type.

What is a universal blood recipient?

AB-positive is the universal recipient — individuals with AB+ blood can receive red blood cells from any blood type. However, for plasma, AB is the universal donor.
