NURSING CARE OF THE CLIENT: RESPIRATORY SYSTEM
![Page 2: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/2.jpg)
Respiratory System
Its primary function is delivery of oxygen to the lungs and removal of carbon dioxide from the lungs.
![Page 3: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/3.jpg)
Thoracic Cavity
The inside of the chest cage is called the thoracic cavity.
Contained within the thoracic cavity are the lungs, cone-shaped, porous organs encased in the pleura, a thin, transparent double-layered serous membrane lining the thoracic cavity.
![Page 4: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/4.jpg)
The Physiology of the Lungs The right lung is larger than the left and is
divided into three sections or lobes: upper, middle, and lower.
The left lung is divided into two lobes: upper and lower.
The upper portion of the lungs is the apex; the lower portion is the base.
![Page 5: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/5.jpg)
Conducting Airways
The conducting airways are tubelike structures that provide a passageway for air as it travels to the lungs.
The conducting airways include the nasal passages, mouth, pharynx, larynx, trachea, bronchi, and bronchioles.
![Page 6: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/6.jpg)
Pharynx Larynx Trachea
The conducting airways that connect nasal passages and mouth to the lower parts of the respiratory tract.
The passageway for air entering and leaving the trachea and containing the vocal cords.
Commonly known as the windpipe, this tube is composed of connective tissue mucosa and smooth muscle supported by C-shaped rings of cartilage.
![Page 7: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/7.jpg)
Bronchi, Bronchioles
Two tubes, the right and left primary bronchi, that each pass into its respective lung.
Within the lungs, the bronchi branch off into increasingly smaller diameter tubes until they become the terminal bronchioles.
![Page 8: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/8.jpg)
Respiration
A process of gas exchange necessary to supply cells with oxygen for carrying on metabolism, and to remove carbon dioxide produced as a waste by-product.
Two types of respiration: external and internal.
![Page 9: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/9.jpg)
External & Internal Respiration
The exchange of gases between the inhaled air and the blood in the pulmonary capillaries.
The exchange of gases at the cellular level between tissue cells and blood in systemic capillaries.

Assessment
Auscultation(Listening for Normal and Adventitious Breath Sounds)
Palpation and Percussion
Inspection(client's color, level of consciousness, emotional state)
(Rate, depth, quality, rhythm, effort relating to respiration)
Health History(allergies, occupation, lifestyle, health habits)
![Page 12: Chapter 18 Respiratory System](https://reader036.fdocuments.in/reader036/viewer/2022081414/54ff09444a7959592e8b525b/html5/thumbnails/12.jpg)
Adventitious Breath Sounds
Fine crackles (dry, high-pitched popping…COPD, CHF, pneumonia)
Coarse crackles (moist, low-pitched gurgling…pneumonia, edema, bronchitis)
Sonorous wheezes (low-pitched snoring…asthma, bronchitis, tumor)
Sibilant wheezes (high-pitched, musical … asthma, bronchitis, emphysema, tumor)
Pleural friction rub (creaking, grating… pleurisy, tuberculosis, abscess, pneumonia)
Stridor (crowing…croup, foreign body obstruction, large airway tumor).
