Atelectasis and AHA Guidelines on Oxygen Administration

Play an AI-generated podcast conversation about this lesson

What is atelectasis?

Collapse of alveolar air spaces (correct)

Expansion of alveolar air spaces

Constriction of bronchial tubes

Increase in lung capacity

When is supplemental oxygen indicated according to AHA guidelines?

For oxygen saturation levels of 90% or less

In all patients with pneumonia

Only when a patient requests it

For patients with respiratory distress or oxygen saturation of 94% or less (correct)

What is the difference between negative pressure ventilation and positive pressure ventilation?

Negative pressure ventilation is used in patients with hypoxemia, while positive pressure ventilation is used in patients with hypercapnia

Negative pressure ventilation forces air into the lungs while positive pressure ventilation draws air into the lungs

Negative pressure ventilation is used during exhalation, while positive pressure ventilation is used during inhalation

Negative pressure ventilation involves airflow from high pressure to low pressure, while positive pressure ventilation forces air into the lungs (correct)
