Pressure Points
Points at the body surface where the pulse may be felt
Blood Pressure
The pressure the blood exerts against the inner walls of the blood vessels, it is the only force that keeps blood circulating continuously even between heartbeats
Arterial Pulse
Pressure wave of blood that can only be felt in the arteries.
Systolic Pressure
The pressure in the arteries at the peak of ventricular contraction
Diastolic Pressure
The pressure when the ventricles are relaxing.
How is blood pressure measured?
Millimeters of mercury (mm/Hg)
Peripheral Resistance
The amount of friction the blood encounters as it flows through the blood vessels
Vasocontriction
Narrowing of the blood, the major action of the sympathetic nervous system
What major role do the kidneys play in the cardiovascular system?
Regulate blood pressure by altering blood volume
What are the 5 effects on blood pressure?
1. Neural Factors: Autonomic Nervous System, 2. Renal Factors:Kidneys,. 3. Temperature, 4. Chemicals, 5. Diet
How does temperature affect blood pressure?
Cold has a vasoconstricting effect while heat has a vasodilating effect
How does chemicals effect blood pressure?
Drugs, Alcohol, Nicotine can increase blood pressure causing vasocontriction
How does diet effect blood pressure?
Foods low in salt and sodium can help to prevent hypertention
What is the normal systolic blood pressure?
110-140 mm Hg
What is the normal diastolic blood pressure
70-80 mm Hg
Hypotension
Low blood pressure with a systolic below 100 mm Hg
Orthostatic Hypotension
Temporary Low Pressure from suddenly changing positions
Hypertension
High Blood Pressure that is 140/90 of higher
What is the percentage of people with primary or essential hypertension?
90%
