Blood Pressure Flashcards
(22 cards)
Reasons for hypotension
Cuts or amputated limbs, drugs or hormones
How does high intakes of salts increase blood pressure
Retains water. causing greater fluid volume lead to blood greater volume
What can Increase blood pressure levels
Diet and lifestyle
How does plaque increased blood pressure?
Formed by the fatty deposits from digested foods; lines the walls of the arteries and make the radius smaller, increasing the blood pressure
Arteries must have
Elastic expandible walls
The term diastolic pressure or diastole refers to
The blood pressure when the heart is at rest
The term systolic pressure or Systole refers to
The pressure when the ventricles contract
Example of hypotension blood pressure
110/70
Hypertension
High blood pressure
Hypotension
Low blood pressure
Blood pressure is….
Not constant
Proper kidney function can only be maintained if there is….
Sufficient pressure for filtration
What Blood pressure reading is quite normal?
120/80
What monitors blood pressure changes that need to be made ?
The hypothalamus (part of the brain)
120/80
120- systolic Reading as ventricles contract
80-diastolic reading as the heart relaxes
What volume of blood do the ventricles pump each time they contract?
Approximately 70 mL
During hypotension, blood….
Does not reach all organs
Reasons for high blood pressure-
Stress, plaques, high salt intake, smoking, stimulants, lack of exercise, diet (amount and type) working too hard, age, sex, race
How does a body or just blood pressure?
Monitored by the hypothalamus part of the brain, the blood can dilate (widen) arterials thus slowing by pressure in them or constrict (barrow) them to raise blood pressure
Pulse
As blood is pumped through the arteries, the arterial walls swell and then recoil. The swelling can be felt in any artery that runs close to the surface
Where is blood pressure normally measured?
Along the brachial artery of the arm
Blood pressure
The force of blood against a blood vessel walls
