Nursing 208 Oxygenation || 100% Verified Answers.
Major function of lungs correct answers Gas Exchange
Oxygenating blood and removing CO2
Gas Exchange Will Depend on correct answers Having open airways
ability to expand lungs
gas diffusion from Alvli into blood stream, and from blood stream into cells
functioning cardio vascular system
How many lobes do the lungs have correct answers 3 on right and 2 on left
Space between chest walls and lungs correct answers Plural Space
First Step in Oxygenation correct answers (1) Ventilation (The process of moving gases into and
out of the lungs)
Second Step in Oxygenation correct answers (2) Perfusion (The ability of the cardiovascular
system to pump oxygenated blood to the tissues and return deoxygenated blood to the lungs)
Third Step in Oxygenation correct answers Diffusion (Exchange of respiratory gases in the
alveoli and capillaries)
Factor that will affect oxygenation correct answers Having working respiratory system
Alveolar Gas Exchange correct answers back and forth traffic of O2 and CO2 across the
respiratory membrane
O2 from inhaling is diffused through alvelor and C02 from the body diffuses back to be exhaled
,Factors affecting Ventilation correct answers * Clear airways
* Intact CNS
* Intact thoracic cavity that fully expands and contracts
* Intact alveoli
- Adequate pulmonary compliance and recoil (lung tissues functing)
Compliance correct answers ability for lungs to expand and contract, change volume depending
on amount of recoil and surface tension
Recoil correct answers ability for lung to retain shape
Surface Tension correct answers the result of our liquid interchange at each alveolus, with
surfactant it reduces tension allowing the lung to inflate easier
Surfactant correct answers chemical produced in the lungs to maintain the surface tension of the
alveoli and keep them from collapsing
Muscular effort correct answers contraction of diaphragm and intercostal muscles
Transport of O2 and CO2 correct answers O2 attaches to the hemoglobin on RBC, bring O2
around body and picks up C02 to be diffused out and exhaled
Poor Oxygen Transport correct answers too few RBC and too few Hemoglobin
Causes of Transport/ Anemia Issues correct answers malnutrition, low iron, bleeding out, cancer,
chemo, medications, sickle cell
External factors Affecting Oxygenation correct answers Pollution
, Occupational Factors: jobs
Altitude
Heat and cold
Life Style Factors Affecting Oxygenation correct answers Mobility
Emtions and stress
Nutrition: low iron or overweight ( claughed Arties )
Smoking
Drugs/ Alcohol
Developmental Factors Affecting Oxygenation correct answers Youngs: not as efficient, easily
sick
Older Adults: System deterating
Health Status Factors Affecting Oxygenation correct answers Decreased O2 carrying capacity,
not enough Hemoglobin or red blood cells (anemia)
Health Status Factors Affecting Oxygenation correct answers Decreased in inspired O2, not
breathing in enough, (can't expand lungs enough, pain, etc)
Health Status Factors Affecting Oxygenation correct answers Hypovolemia: a decreased volume
of circulating blood in the body. Blood becomes too thick so the arties get clogged
Health Status Factors Affecting Oxygenation correct answers Increased metabolic rates due to
fever
Health Status Factors Affecting Oxygenation correct answers Surgery
Health Status Factors Affecting Oxygenation correct answers Chest wall movement:
