Cardiac Illness Flashcards
1
Q
Varicose Veins
A
- Individuals who have spent long periods of time standing or sitting may damage the
valves in the veins of the lower legs - skeletal muscles in the lower body do not move or contract enough to allow the blood to return to the heart.
- If the valves are not functioning properly, there is
a greater accumulation of blood in the veins - the veins stretch but do not rebound,
creating a bulging - circulation to the brain is decreased, which may cause fainting
- may increase risk of blood clotting
2
Q
Anemia
A
- indicates low hemoglobin levels which leads to low oxygen levels
- Commonly caused by bleeding from an external injury or from internal bleeding (ulcers in the stomach)
- Can result from a variety of diseases, but usually is caused by a deficiency of iron in the diet
- Postoperative Anemia is known risk after surgery
3
Q
Coronary Artery Disease
A
- buildup of plaque along the sides or inside artery walls
- Excess of fat, cholesterol, calcium, and other substances forms the plaque
- Loss of elasticity and hardening of the arteries
- Reduces or blocks flow of blood, preventing the fluid from being able to be pumped around the body
4
Q
Hypertension
A
- High blood pressures
- makes heart pump more blood
- volume of the circulatory system does not increase, the pressure within the
system increases. - Kidney disease= more fluid to
be retained in the blood= increase in the volume of blood= blood pressue
-
5
Q
atrifcial blood
A
- tryng to be artifical blood because a supply of blood may not always be safe
- focusing on the transport function of blood
- two works in progress:
-hemoglobin-based oxygen
carriers (uses cow or human blood, but could have a toxic effect on kidneys)
perfluorocarbon emulsions (synethic)
6
Q
CBC
A
Complete blood count
A hemocytometer is used to estimate # of ethrocytes, leuckocytes and platelets in a volume of blood
