What is atelectasis?
Collapse of the alveolar air spaces of the lung due to airway obstruction
When is supplemental oxygen indicated according to AHA guidelines?
For patients with oxygen saturation of 94% or less on room air and no respiratory distress
What is the main difference between negative and positive pressure ventilations?
Negative pressure ventilation draws air into the lungs, while positive pressure ventilation forces air into the lungs

By allowing vomitus to drain from the mouth easily
Test your knowledge on the signs and symptoms of emphysema, a chronic obstructive pulmonary disease characterized by distention of the alveoli and destructive changes in the lung parenchyma. Questions cover topics like shortness of breath with exertion, chronic chest infections, productive cough, barrel-shaped chest, orthopnea, and cor pulmonale.
