Question
Match the various pressures to the appropriate respiratory event (assume thoracic cavity is intact i.e. no holes) Atmospheric Pressure mmH Intrapulmonic Pressure (mmHg) Intrapleural Pressure +(mmHg) 760 760 760 760 64 758 760 760 758 756 757 760 35. For Row A. a. normal inhalation c. no air movement b. normal exhalation d. hard exhale e. pneumothorax 36. For Row B a. normal inhalation c. no air movement b. normal exhalation d. hard exhale e. pneumothorax 37 For Row C a. normal inhalation b. normal exhalation d. hard exhale c. no air movement e. pneumothorax 37 for Row D. a. normal inhalation b. normal exhalation c. no air movement d. hard exhale e. pneumothoraxExplanation / Answer
35. B normal exhalation - air will flow outaide as intrapullmonary pressure is higher than atmospheric pressure.
36. A. Normal inspiration -air will flow into lung as atmospheric pressure is more than intrapullmonary pressure.
37. C. No air movement - as both atmospheric and intrapullmonary pressure is equal.
38. E. Pneumothorax - as intrapleural pressure has become equal to atmospheric pressure (loss of negative intrapleural pressure).
