Disturbances in Circulation Flashcards
(28 cards)
Too much blood; a lesion in which excess blood may be drawn into an area
Hyperemia
Hyperemia usually occurs at this site of the circulation.
Arterial site
It usually occur at the arterial site of the circulation.
Hyperemia
Two type of Hyperemia
a. Active Hyperemia (arterial)
b. Passive Hyperemia (venous)
Passive Hyperemia is also known as
Congestion
Physiologic Hyperemia factors to consider:
a. Post-prandial gastric
b. Blushing
c. Stimulation of erectile tissue
Pathologic (abnormal) Hyperemia factors to consider:
a. Duration (chronic)
b. Extent (general, location)
c. Mechanism (active, passive)
Patterns of Hyperemia
- Acute local active
- Acute local passive
- Chronic local passive
- Chronic general passive
Acute local active
inflammatory
Acute local passive
obstruction
Chronic local passive
obstruction
Cardio-pulmonary problem
Chronic general passive
Example of Chronic General Passive
Congestive heart failure (also called heart failure) or CHF
A long term condition wherein heart can’t pump blood well enough to give your body enough blood supply; as a result, blood and fluids collect in the lungs and leak over time
Congestive Heart Failure (CHF)
Main causes of Congestive Heart Disease (CHF)
Coronary artery diseases
Two types of Congestive Heart Disease (CHF)
Left Sided Heart Failure
Right Sided Heart Failure
The left ventricle is not pumping blood normally away from the lungs.
Left Sided Heart Failure
The heart right ventricle is too weak to pump blood towards the lungs.
Right Sided Heart Failure
Right Sided Heart Failure result in what?
• Swelling of the heart & lungs (all over the body)
• Shortness of breath
Left ventricle of the heart no longer pumps enough around the body, then blood builds up in the pulmonary veins or the blood vessels that carry the blood away from the lungs.
Left Sided Heart Failure
Right ventricle is too weak to pump blood towards the lungs
Right Sided Heart Failure
Example of Left Sided Heart Failure
• shortness of breath
• coughing
the oxygenated blood in the circulatory system
Arterial blood
It carry the oxygen
Hemoglobin
