MECHANICAL VENTILATION ASSESMENT TEST 2024-2025 EXAM COMPLETE
QUESTIONS AND CORRECT DETAILED ANSWERS
Mechanical Ventilation
Ans: A machine used to provide adequate ventilation and oxygenation to a patient
who is unable to adequately ventilate or oxygenate
Quiz Goals of Mechanical Ventilation
Ans: Improve ventilation,Improve oxygenation,Decrease the work of breathing
(support/rest respiratory muscles),Correct life threatening blood gas and acid-base
abnormalities,Ultimate goal=wean patient off!
Quiz Why do we mechanically ventilate a patient?
Ans: Patient is unable to maintain an acceptable PO2,Patient is unable to maintain
an acceptable PCO2,Work of breathing is excessive,Patient is fatigued,Patient is not
breathing due to neurologic impairment i.e. MS, MG, Guillian Barre, CVA,Patient is
not breathing due to drug effects i.e. narcotics, overdose, anesthesia
Quiz Ventilators DO NOT:
Ans: Cure diseased lungs,Complete gas exchange,Oxygenate tissue
Quiz Ventilators DO:
Ans: Support ventilation while the underlying cause is explored and hopefully
resolved,Administer necessary oxygen levels while therapy is undertaken,
Quiz ventilation
Ans: - the act of inspiring and exhaling
Quiz Respiration
, Ans: Respiration - gas exchange at the alveolar capillary level and at the cellular
level
Quiz Noninvasive Positive-pressure Ventilation:Purpose:
Ans: Keep Alveoli Open,Improve gas Exchange without invasive ventilation
Quiz types of positive pressure vent
Ans: BiPAP (bilevel positive airway pressure), CPAP (continuous positive airway
pressure)
Quiz Requirements to Mechanically Ventilate
Ans: A cuffed endotracheal tube,A cuffed tracheotomy tube,
Quiz Difference mechanical ventilation vs. spontaneous breathing
Ans:
Quiz Mechanical ventilation
Ans: Positive pressure=pushes air into the lungs, diaphragm pushed
down,Expiration occurs spontaneously
Quiz Spontaneous breathing
Ans: Vacuum created by diaphragm dropping creating negative pressure pulling air
into the lungs,Expiration occurs passively
Quiz Cardiovascular response to controlled ventilation
Ans: Hypotension, Fluid retention
Quiz - During inspiration lungs are expanded by positive pressure
Ans:
Quiz - As lungs expand, intrathoracic pressure increases and inhibits blood return to
the heart
Ans: Decreased venous return (preload) leads to decreased cardiac output which
leads to decreased BP,Decreased cardiac output leads to decreased blood flow to
the kidneys then the RAA system is activated and fluid is retained
Quiz Positive Pressure Ventilator Cycles
Ans:
Quiz Pressure cycled -
