NUR 326 Perfusion and Clotting

NUR 326 Perfusion and Clotting
1. Central Perfusion
-Generated by cardiac output
-Outcome of electrical and mechanical factors
-Requires adequate cardiac function, blood pressure, and blood volume
2. Central perfusion
Impairment of ... occurs when cardiac output is inadequate.
3. Cardiac output
Reduction of.....results in a reduction of oxygenated blood reaching the body tissues (systemic
effect).
-If severe, associated with shock
-If untreated, leads to ischemia, cell injury, and cell death
4. Stroke volume
Cardiac output = ..... X heart rate
5. Local (tissue) perfusion
Volume of blood that flows through target tissue (re- sults from hydrostatic pressure)
-Facilitates delivery of 02, fluid, and nutrients to the cells.
6. Tissue perfusion
Impairment of .... is associated with loss of vessel potency or permeability, or inadequate
central perfusion.
-Results in impairment of blood flow to the affected body tissue (localized effect)
-Leads to ischemia, and ultimately, cell death if not corrected.
7. Tissue perfusion
Alterations in .... can occur due to
-Poor central perfusion (cardiac output from MI, shock, or acute blood loss)
-Mechanisms within organ such as
blocked blood vesselsupplying tissue or excessive edema
