What factors contribute to the work of breathing - ANSWER ✔✔The
effort required to expand and contract the lungs.
Inspiration and expiration
Surfactant
Atelectasis
Compliance and airway resistance
The amount of energy expended on breathing depends on? -
ANSWER ✔✔1-the rate and depth of breathing, the ease with which
the lungs can be expanded (compliance)
,2-airway resistance.
Inspiration - ANSWER ✔✔an active process, stimulated by chemical
receptors in the aorta.
Expiration - ANSWER ✔✔passive process that depends on the
elastic recoil properties of the lungs, requiring little or no muscle work
Surfactant - ANSWER ✔✔a chemical produced in the lungs to
maintain the surface tension of the alveoli and keep them from
collapsing
Atelectasis - ANSWER ✔✔a collapse of the alveoli that prevents
normal exchange of oxygen and carbon dioxide.
What can cause atelectasis? - ANSWER ✔✔1-lungs collapse-can be
caused by puncture of lungs
2-asthma that irrigates airways,
3-pneumonia,
4-tb,
4-pneomothorax,
5-hemothorax,
6-surgery due to anesthesias
,7-premature birth before 34 weeks
What are the Accessory muscles - ANSWER ✔✔-overuse of the
diaphragm can increase lung volume during inspiration
-Traps
-sternocleidomastoid
-intern/external intercostals
Respiratory compliance - ANSWER ✔✔normal elasticity during
breathing
decreased compliance - ANSWER ✔✔occurs in asthma and other
respiratory issues, you don't have the same elasticity
Impact of increased airway resistance and decreased lung compliance -
ANSWER ✔✔-sob
-reduced perfusion
-ineffective gas exchange
-increase RR
-increase in respiratory metabolism due to decreased oxygen levels
Decreased perfusion leads to: - ANSWER ✔✔Brain-Stroke
Kidney-renal failure

, Liver-failure
Heart-MI
Prolonged use of the accessory muscles - ANSWER ✔✔does not
promote effective ventilation and causes fatigue.
Accessory muscles of respiration can - ANSWER ✔✔increase lung
volume during inspiration
During assessment of accessory muscles check for - ANSWER
✔✔observe for elevation of the patient's clavicles during inspiration
Elevation of clavicle indicates? - ANSWER ✔✔ventilatory fatigue
air hunger
decreased lung expansion.
Tidal volume is - ANSWER ✔✔the amount of air exhaled following a
normal inspiration.
Residual volume - ANSWER ✔✔the amount of air left in the alveoli
after a full expiration
Forced vital capacity - ANSWER ✔✔the maximum amount of air that
can be removed from the lungs during forced expiration.
