NCM 203 NURSING CARE MANAGEMENT: THE RESPIRATORY SYSTEM Respiratory System Its primary function is delivery of oxygen to the lungs and removal of carbon dioxide from the lungs. 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. 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. 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. 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. 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. 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. 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. Signs & Symptoms 1. 2. 3. 4. 5. 6.

Can result from severe left ventrical failure, rapid administration of I.v. fluids, inhalation of noxious gases, or opiate or barbiturate overdose. Adult Respiratory Distress Syndrome A life-threatening condition characterized by severe dyspnea, hypoxemia, and diffuse pulmonary edema. Usually follows major assault on multiple body systems or severe lung trauma. Bronchiectasis A chronic dilation of the bronchi. Main causes of this disorder are pulmonary TB infection, chronic upper respiratory tract infections, and complications of other respiratory disorders of childhood, particularly cystic fibrosis. Neoplasms of the Respiratory Tract Benign neoplasms. Lung cancer. Cancer of the larynx. Epistaxis A hemorrhage of the nares or nostrils. May be unilateral (most common) or bilateral. Blood loss can be minimal to severe. Smoking Cigarette smoking is indicated as a major causative factor in the development of respiratory disorders, such as lung cancer, cancer of the larynx, emphysema, and chronic bronchitis.
