Anemia results from blood loss may be caused by either ?
Acute or chronic problems
Acute blood loss occurs as a result of sudden?
Hemorrhage
The sources of chronic blood loss are similar to those as ?
Example?
Iron deficiency anemia
Slow bleeding stomach ulcer
What are causes of acute blood loss? (3)
Trauma
Complications of surgery
Conditions or disease that disrupt vascular integrity
What are the major 2 concerns in conditions or disease that disrupt vascular integrity?
Sudden reduction in the total blood vascular volume can lead to
- Hypovolemic shock
- Body compensated by increasing plasma volume but RBC remain low
While the body will maintain its blood volume by increasing the plasma volume. This will help preserver circulating fluid volume
However the number of red blood cell available to carry 02 will?
Significant decrease
Clinical manifestations for acute blood loss are related to?
Body’s attempts to maintain adequate circulating volume and meet O2 requiments
What is more important
Clinical signs & symptoms
Or
Laboratory valves?
