Quiz 4 Flashcards
The reduction in alveolar minute ventilation leading to an insufficient elimination of CO2 from the body is known as…
hypoventilation
The insufficient amount of oxygen in arterial blood that results in reduced oxygen concentration is known as…
hypoxemia
The clinical situation where there is below normal arterial blood pressure is known as…
hypotension
The clinical situation where there is a body temperature that is below normal is known as…
hypothermia
Which of the following PaCO2 levels would be considered also known Hypercapnia?
50 mm Hg
Which of the following are contributors to hypoventilation?
anesthetic agents
increased mechanical dead space
exhausted CO2 absorbent
How can hypoventilation be prevented?
Providing an anesthetic patient 1 – 2 positive pressure ventilations / minute.
Which of the following is the most common cause of Hypoxemia?
V/Q mismatch
V/Q mismatch is defined as…
ventilation of a lung area without sufficient perfusion of the lung area.
Which of the following would be a cause of V/Q mismatch?
Long term lateral recumbency of a canine anesthesia patient
Atelectasis
Bronchial intubation
Severe hypoventilation, which can lead to hypoxemia, is of most concern during which period of anesthesia?
Recovery
Which of the following is / are a method(s) for preventing Hypoxemia?
Intubating and placing an anesthetic patient on 100% oxygen regardless of inhalation anesthetic use.
Treating Hypoxemia can be difficult. Of the following, which option would be recommended?
Positive pressure ventilation, holding the inspiratory pressure of 15 – 20 cm of H2O for 3-5 seconds.
A MAP that is less than 60 mm Hg in an anesthetized cat is an indication of…
Hypotension
Excessive Inspiratory Pressure (Inspiratory positive pressure ventilation – IPPV) can lead to…
increased pressure on the vena cava resulting in decreased blood returning to the heart (preload)
rupture of alveoli
pneumothorax and hypoxia
