ACMA01H3 Lecture Notes - Functional Residual Capacity, Lung Volumes, Multiple Organ Dysfunction Syndrome
1. What risk factors are implicated in the development of post-operative atelectasis?
2. What are the five basic pathophysiologic mechanisms that cause hypoxemic respiratory failure?
3. Adult respiratory distress syndrome is characterized by:
a. Narrowing of the alveolar-arterial O2 gradient
b. Supplemental oxygen usually able to maintain systemic oxygen saturation (arterial PaO2
over 65mmHg)
c. Intrapulmonary shunting
d. Increased pulmonary compliance
e. Increased functional residual capacity
4. Classically , the order of organ system loss in patients with multi-organ failure is
a. Lung, liver, gastrointestinal (GI), kidney
b. Liver, lung, GI, kidney
c. GI, kidney, liver, lung
d. Kidney, GI, lung, liver
e. Kidney , lung, liver, GI
5. The effects of upper abdominal surgery on respiratory physiology include the following except:
a. Tonic and phasic contraction of abdominal expiratory muscles
b. Reflex inhibition of phrenic nerve activity resulting in decreases diaphragmatic function
c. Increased utilization of neck and intercostal inspiratory muscles
d. Increase in lung volume: residual volume, total lung capacity and functional residual
capacity
e. Hypoventilation secondary to residual general anesthesia effect, sedative therapy and
pain
