What is the formula for pulse pressure?
Pulse Pressure = Systolic Pressure – Diastolic Pressure
What is the formula for MAP (Mean Arterial Pressure)?
MAP = Diastolic Pressure + 1/3 × Pulse Pressure
A person has a blood pressure of 140/90 mmHg. What is their pulse pressure?
50 mmHg (140 – 90)
A person has a blood pressure of 140/90 mmHg. What is their MAP?
106.7 mmHg (90 + 50/3)
A person has a blood pressure of 100/65 mmHg. What is their MAP?
76.7 mmHg (65 + 35/3)What does a high pulse pressure indicate?
What does a high pulse pressure indicate?
Greater force of heart contraction; may suggest stiff arteries or cardiovascular stress.
Why is MAP important?
It reflects average arterial pressure and is critical for organ perfusion.
What is a normal MAP range for adequate perfusion?
Typically 70–100 mmHg
What happens if MAP drops below 60 mmHg?
Risk of inadequate blood flow to vital organs.
