Concept of Perfusion - ANSWERS Essential function of cardiovascular and
pulmonary systems to provide a continuous supply of oxygenated blood to every
cell in the body
Essential organ for perfusion - ANSWERS The heart : Generates sufficient
cardiac output to transport blood throughout patent blood vessels for distribution
in the tissues throughout the body
impaired perfusion - ANSWERS Represents wide range of physiologic
processes and conditions
Optimal -> Impaired -> Absent
What does impaired perfusion cause? - ANSWERS Tissue damage:
Ischemia
Necrosis
Central perfusion - ANSWERS Generated by cardiac output
Propels blood to all organs and their tissues
,Impaired Central Perfusion - ANSWERS Clinical manifestation are systemic
when impaired
Causes impaired tissue perfusion
Tissue Perfusion - ANSWERS Volume of blood that flows through tissues
Supplied by flood flow from arteries to capillaries
Amount of blood needed for tissue perfusion - ANSWERS Amount of blood
required by organs vary
Ex. Brain needs more than skeletal system
Impaired Central perfusion - Assessment findings: - ANSWERS Hypotension
Tachycardia
Change in mental status
Shortness of breath
S1, S2, S3, S4 or murmurs
Change in heart rhythm
Peripheral edema
Diaphoresis and Anxiety
Impaired Tissue perfusion - Assessment findings: - ANSWERS Lower
extremities:
Pale, cool skin
Less hair on legs
Diminished dorsalis pedal and posterior tibial pulses
,Slowed capillary refill
Kidneys:
Decreased urine output
Brain:
Depends on extent of ischemia and areas affected
Perfusion - Roll of the Nurse - ANSWERS - Promote healthy behaviors to
optimize perfusion
- Identify individuals at risk
- Recognize when individuals are experiencing impaired perfusion
- Respond with appropriate nursing interventions
Perfusion - Non modifiable risk factors - ANSWERS - Age
- Gender
- Genetics - Heredity - Family history
- Race
- Personal health history
Perfusion - modifiable individual risk factors - ANSWERS - Smoking
- Sedentary lifestyle
- Obesity
- Diabetes mellitus
, - Hypertension
Perfusion - Secondary risk factors - ANSWERS - Stress
- Alcohol
- Diet and nutrition
Perfusion Screenings - ANSWERS Blood pressure < 120/80
Chest X-Ray
Serum Cholesterol, Triglycerides, Lipids
ECG
Stress Test
Echocardiography
Normal total cholesterol level - ANSWERS <200 mg/dL
Normal LDL - ANSWERS <100 mg/dL
Normal HDL - ANSWERS >60 mg/dL
Normal triglycerides - ANSWERS <150 mg/dL
ECG (electrocardiogram) - ANSWERS A recording of the electrical
activity/changes of the heart
