- Question 6 In patients with pulmonary fibrosis, alveolar thickness is increased (due to tissue necrosis), and the alveolar area is reduced. Explain how increased alveolar thickness and the decreased area would affect the diffusion of oxygen from lung alveoli into capillary blood. (Use Fick’s equation to explain how oxygen diffusion will be affected when alveolar thickness increases and area decreases).Question 37 Which of the following findings of a respiratory assessment would be found in an infant but NOT a child? Question 37 options: Intercostal recession Supraclavicular recession Nasal flare See-saw breathingQuestion 60 You embark on a hiking trip on Mt.
