NUR 105 Perfusion
- Heart
Answer hollow muscular organ that most oxygenated blood through arteries to all body tissues
- Arteries
Answer Blood vessels that are strong, tough, and flexible which provide oxygenation and nutrients to body tissue
- Veins
Answer blood vessels that return deoxygenated blood + waste produces it to the heart
- Capillaries
Answer blood vessels that connect arteries + veins
- Perfusion
Answer the flow of blood through arteries and capillaries delivering nutrients
- oxygen to cells and removing cellular waster products
- Optimal perfusion
Answer dependent on normal functioning of both respiratory + cardiovascular system
- Scope of perfusion
Answer 1 / 3
-cardiovascular health is essential for optimal perfusion
-electrical conduction system
- Sufficient stroke volume
Answer the amount of blood ejected from the left ventricle of the heart in one contraction
-seen throughout lifespan
- Optimal perfusion expectations
- skin pink + warm to touch
Answer
- extremities pink + warm to touch
- nail beds pink
- capillary refill <3 seconds
- heart sounds regular rhythm
- heart rate between 60-100 bpm
- peripheral pulse palpable-strong
- no edema
- CSM intact
- no tingling numbness in extremities
- lab within normal limits
- UOP > 30ml/hr
- telemetry - sinus rhythm
- Ischemia
Answer insufficient flow of oxygenated blood to tissues
-may result in hypoxia + subsequent cellular injury + death -reversed if caught in time
- Infarction
Answer 2 / 3
obstruction of blood supply to an organ or tissue
-lead to death of organ/tissue -myocardial infarction
- Anoxia
Answer absence or deficiency of oxygen reaching the tissues
-severe hypoxia-total lack of oxygen in body tissue
- Necrosis
Answer the death of most or all the cells in tissue or an organ due to a lack of blood supply
- Signs + symptoms of impaired perfusion
- Angina
Answer
- Synscope
- Diaphoretic
- Dyspnea, shortness of breath
- Edema
- Palpitations
- Cardiac arrhythmia
- Cyanosis
- Angina
Answer uncomfortable pressure, squeezing, pain that can radiate across the chest, into the arms, jaw, shoulders, upper back
-due to insufficient coronary blood flow not enough oxygen to meet myocardial demand
