Textbook Question
Chapter 21, Problem 12RQ
In mouth-to-mouth artificial respiration, the rescuer blows air from his or her own respiratory system into that of the victim. Which of the following statements are correct?
(1) Expansion of the victim’s lungs is brought about by blowing air in at higher than atmospheric pressure (positive-pressure breathing).
(2) During inflation of the lungs, the intrapleural pressure increases.
(3) This technique will not work if the victim has a hole in the chest wall, even if the lungs are intact.
(4) Expiration during this procedure depends on the elasticity of the alveolar and thoracic walls.
(a) all of these, (b) 1, 2, 4, (c) 1, 2, 3, (d) 1, 4.

He had similar symptoms approximately 1 year ago with a chronic obstructive pulmonary disease (COPD) exacerbation requiring hospitalization. (a) What is obstructive lung disease? How does it affect the oxygen and carbon dioxide content in the arterial blood? (b) Describe how the obstructive lung disease can be diagnosed by the spirometer.

How can it affect pulmonary function?arrow_forwardThe reason the elasticity and surface tension of the lungs do not cause the lungs to collapse between exhalation and inhalation is because the intrapulmonary pressure is higher than the atmospheric pressure the intrapleural pressure is less than the intrapulmonary pressure the intrapulmonary pressure is less than the atmospheric pressure the intrapleural pressure is greater than the atmospheric pressure more than one of the abovearrow_forward
