Chapter 25, “Structure and Function of the Pulmonary System”
This chapter provides information relating to the structure and function of the pulmonary system to illustrate normal pulmonary function. It focuses on gas transport to build the foundation for examining alterations of pulmonary function.
Chapter 26, “Alterations of Pulmonary Function”
This chapter examines clinical manifestations of pulmonary alterations and disorders of the chest wall and pleura. It covers the pathophysiology, clinical manifestations, evaluation, and treatment of obstructive lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis, and emphysema.
Chapter 27, “Alterations of Pulmonary Function in Children”
This chapter focuses on alterations of pulmonary function that affect children. These alterations include disorders of the upper and lower airways.

Chapter 9, “Pulmonary Disease”
This chapter begins with an overview of normal structure and function of the lungs to provide a foundation for examining various lung diseases such as asthma and chronic obstructive pulmonary disease (COPD).

This article provides information relating to the epidemiology, genetic features, clinical presentation, and diagnosis of sarcoidosis. It also examines how several body systems are impacted by organ involvement.
Consider the following three scenarios:
Ms. Teel brings in her 7-month-old infant for evaluation. She is afraid that the baby might have respiratory syncytial virus (RSV) because she seems to be coughing a lot, and Ms. Teel heard that RSV is a common condition for infants. A detailed patient history reveals that the infant has been coughing consistently for several months. It’s never seemed all that bad. Ms. Teel thought it was just a normal thing, but then she read about RSV. Closer evaluation indicates that the infant coughs mostly at night; and, in fact, most nights the baby coughs to some extent. Additionally, Ms. Teel confirms that the infant seems to cough more when she cries. Physical examination reveals an apparently healthy age- and weight-appropriate, 7-month-old infant with breath sounds that are clear to auscultation. The infant’s medical history is significant only for eczema that was actually quite bad a few months back. Otherwise, the only remarkable history is an allergic reaction to amoxicillin that she experienced 3 months ago when she had an ear infection.
Kevin is a 6-year-old boy who is brought in for evaluation by his parents. The parents are concerned that he has a really deep cough that he just can’t seem to get over. The history reveals that he was in his usual state of good health until approximately 1 week ago when he developed a profound cough. His parents say that it is deep and sounds like he is barking. He coughs so hard that sometimes he actually vomits. The cough is productive for mucus, but there is no blood in it. Kevin has had a low-grade temperature but nothing really high. His parents do not have a thermometer and don’t know for sure how high it got. His past medical history is negative. He has never had childhood asthma or RSV. His mother says that they moved around a lot in his first 2 years and she is not sure that his immunizations are up to date. She does not have a current vaccination record.
Maria is a 36-year-old who presents for evaluation of a cough. She is normally a healthy young lady with no significant medical history. She takes no medications and does not smoke. She reports that she was in her usual state of good health until approximately 3 weeks ago when she developed a “really bad cold.” The cold is characterized by a profound, deep, mucus-producing cough. She denies any rhinorrhea or rhinitis—the primary problem is the cough. She develops these coughing fits that are prolonged, very deep, and productive of a lot of green sputum. She hasn’t had any fever but does have a scratchy throat. Maria has tried over-the-counter cough medicines but has not had much relief. The cough keeps her awake at night and sometimes gets so bad that she gags and dry heaves.
Review the three scenarios, as well as Chapter 26 and Chapter 27 in the Huether and McCance text.
Select one of the scenarios and consider the respiratory disorder and underlying alteration associated with the type of cough described.
Identify the pathophysiology of the alteration that you associated with the cough.
Select two of the following factors: genetics, gender, ethnicity, age, or behavior. Reflect on how the factors you selected might impact the disorder.
Post a description of the disorder and underlying respiratory alteration associated with the type of cough in your selected scenario. Then, explain the pathophysiology of the respiratory alteration. Finally, explain how the factors you selected might impact the disorder.
