Exam 2: Ventilation

What is the term for the breathing condition in which short episodes of rapid, uniform deep breaths are followed by 10-30 seconds of apnea?

Which of the following would shift the volume-pressure curve to the right? ? I. Acute asthma episode II. Pneumothorax III. Pleural effusion IV. Pulmonary edema

In which breathing pattern is an individual only able to breathe comfortably in the upright position?

When the average alveolus is fully distended, what is the approximate surface tension?

What are the boundaries of anatomic dead space?

What is the term for alveolar ventilation without pulmonary capillary perfusion?

What is the term for the molecular cohesive force at a liquid-gas interface?

What is the term for the breathing pattern in which the depth of breathing increases?

When the radius of the bronchial airways decreases during exhalation, what change must occur to maintain a constant gas flow?

Which gas law states that at constant temperature, a volume of gas varies inversely proportional to its pressure?

In the presence of restrictive lung disorders, how do patients typically offset the decreased time constants?

Which flow pattern occurs in airways at high flow rates and high pressure gradients?
