Term that describes a heart that is not pumping adequate amounts of blood? | Congestive heart failure |
Congestive heart failure | Results in blood "backing up" in the body, which produces congestion, or abnormal fluid accumulation, upstream from the failing heart. |
First sign that the heart is starting to fail? | Drop in cardiac output- how much blood the heart is pumping back into the body. |
Outcomes of congestive heart failure (CHF): | Fight-or-flight response causes the heart to increase blood flow & blood pressure by making the heart beat harder & faster. Eventually this weakens the heart & causes further decrease in cardiac output. Cycle continues until heart gives out completely. |
Iron | An essential element. It is used to bind oxygen & carry it to tissues where it is needed in the mitochondria to generate adenosine triphosphate (ATP). W/out it , O2 levels that can be carried by blood is reduced, leading to fatigue & exercise intolerance |
Chronic __________ reduces the level of iron in the body. | blood loss |
Iron deficiency anemia | Ongoing blood loss. W/out adequate levels of iron, the body is not able to make hemoglobin & adequate #s of red blood cells. |
Clinical signs of iron deficiency anemia: | Pale mucous membranes, fatigue, bounding pulses, & galloping heart rhythm. Can result from a puppy/kitten having a flea infestation. |
How is iron deficiency anemia treated? | By stabilizing the patient with blood transfusions, giving oral & injectable iron supplements, & eliminating the cause of the blood loss. |
