  10. 10. LOWER RESPIRATORY TRACT <br />LUNGS <br />Located in in the pleural cavity in the thorax <br />above the clavicles to the diaphragm - the diaphragm (the major muscle of respiration)<br />The bronchi are lined with cilia which propel mucus up & away from the lower airway to the trachea where it can be expectorated or swallowed <br />RIGHT LUNG <br />larger than the left<br />divided into 3 lobes: the upper, middle & lower lobes <br />LEFT LUNG <br />narrower than the right lung to accommodate the heart ; <br />divided into 2 lobes <br />LUDY MAE B. NALZARO, RN, MN<br />9<br />
  11. 11. Innervation of the respiratory structures is accomplished by the PHRENIC NERVE (C3), VAGUS NERVE & THORACIC NERVES <br />PARIETAL PLEURA - lines the inside of the thoracic cavity including the upper surface of the diaphragm <br />VISCERAL PLEURA - covers the pulmonary surfaces <br />Pleural cavity contains serous fluid<br />A thin fluid (surfactant) layer produced by the cells lining the pleura, lubricates the visceral & parietal pleura, allowing them to glide smoothly and painlessly during respiration <br />LUDY MAE B. NALZARO, RN, MN<br />10<br />
  12. 12. Lung Volumes<br />Ave total capacity of 5900mL (19 y.o. man)<br />A person cannot exhale all the air from the lungs<br />1200mL of air remains in the lungs even after forceful expiration<br />RESIDUAL VOLUME<br />Prevents collapse of the lung structure during expiration<br />Volume of air that moves in and out with each breath<br />TIDAL VOLUME<br />Usually 500ml<br />The amount of air inhaled during deep breathing (beyond tidal volume)<br />INSPIRATORY RESERVE VOLUME<br />Amount of air exhaled forcibly<br />EXPIRATORY RESERVE VOLUME<br />LUDY MAE B.

  19. 19. LOWER RESPIRATORY TRACT <br />BRONCHIOLES <br />Contain no cartilage & depend on the elastic recoil of the lung for patency <br />Terminal bronchioles contain no cilia & don’t participate in gas exchange <br />From nose to terminal bronchioles no gas exchange happens and are considered anatomic dead space<br />ALVEOLAR DUCTS & ALVEOLI <br />used to indicate all structures distal to the terminal bronchiole <br />Alveolar ducts branch from the respiratory bronchioles <br />Alveolar sacs which arise from the ducts contain clusters of alveoli which are basic units of gas exchange <br />Cells in the walls of the alveoli secrete surfactant <br />reduces the surface tension in the alveoli <br />without surfactant the alveoli would collapse <br />LUDY MAE B. NALZARO, RN, MN<br />14<br />
  20. 20.
  21. 21. Ventilation<br />Movement of air in and out of the lungs<br />3 forces:<br />Compliance<br />Refers to ease of the lungs to expand and indicates the relationship between the volume and pressure of the lungs<br />Normal: Lungs are elastic so they recoil<br />Diseases the cause fibrosis of the lungs results in “stiff lungs” with long compliance<br />Requires high inspiratory pressure to achieve the set volume of gas<br />Emphysema that damage the elastic structure of the alveolar wall result in ”floppy lungs” with great compliance but poor recoil<br />LUDY MAE B. NALZARO, RN, MN<br />16<br />
  22. 22. Surface tension<br />Surfactant in the alveolar lining lowers surface tension and increases compliance and aids in ventilation and oxygenation<br />Deficiency of surfactant (premature infants) results to stiff lungs = RDS<br />Muscular effort of inspiratory muscles<br />Contraction of the diaphragm and external intercostal muscles enlarges the size of the thorax<br />LUDY MAE B. NALZARO, RN, MN<br />17<br />
  23. 23. Role of Pulmonary Surfactant<br />Surfactant decreases surface tension which: <br /><ul><li>increases pulmonary compliance (reducing the effort needed to expand the lungs)
  24. 24. reduces tendency for alveoli to collapse </li></ul>LUDY MAE B. NALZARO, RN, MN<br />18<br />

  270. 270. Tracheostomy care is delivered at least q 8 hrs; or more often as needed
  271. 271. Tracheostomy dressings are pre-cut to fit around trach and protect neck and skin from secretions</li></li></ul><li>Air Warming and Humidification<br /><ul><li>The tracheostomy tube bypasses the nose and mouth, which normally humidify, warm, and filter the air.
  272. 272. Air must be humidified.
  273. 273. Maintain proper temperature.
  274. 274. Ensure adequate hydration.</li></li></ul><li>Tracheostomy Suctioning<br /><ul><li>Suctioning maintains a patent airway and promotes gas exchange.
  275. 275. Assess need for suctioning from the client who cannot cough adequately.
  276. 276. Suctioning is done through the nose or the mouth.
  277. 277. Suctioning can cause:
  278. 278. Hypoxia (see causes to follow)
  279. 279. Tissue (mucosal) trauma
  280. 280. Infection
  281. 281. Vagal stimulation and bronchospasm
  282. 282. Cardiac dysrhythmias from hypoxia caused by suctioning</li></li></ul><li>Things to Remember about Suctioning<br /><ul><li>80 – 120 mmHg suction
  283. 283. Less is better
  284. 284. Hyperoxygenate before suctioning
  285. 285. Instill NS only if secretions are dry or to induce cough
  286. 286. Insert tube until resistance, then withdraw 1-2 cm
  287. 287. Must be past end of artificial airway
  288. 288. Less than 10 seconds
  289. 289. Twist catheter as it is withdrawn
  290. 290. Any suctioning causes mucosal damage </li></li></ul><li>Causes of Hypoxia in Clients with Tracheostomy<br /><ul><li>Ineffective oxygenation before, during, and after suctioning
  291. 291. Use of a catheter that is too large for the artificial airway
  292. 292. Prolonged suctioning time
  293. 293. Excessive suction pressure
  294. 294. Too frequent suctioning</li></li></ul><li>Weaning from a Tracheostomy Tube<br /><ul><li>Weaning is a gradual decrease in the tube size and ultimate removal of the tube.
  295. 295. Cuff is deflated as soon as the client can manage secretions and does not need assisted ventilation.
  296. 296. Change from a cuffed to an uncuffed tube.
  297. 297. Size of tube is decreased by capping; use a smaller fenestrated tube.
  298. 298. Tracheostomy button has a potential danger of getting dislodged.</li></li></ul><li>Mechanical Ventilation<br />Positive or negative pressure breathing device to maintain ventilation or oxygenation<br />Indications<br />Negative pressure<br />“Iron lung,” chest cuirass<br />Positive pressure<br />Pressure-cycled<br />Time-cycled<br />Volume-cycled<br />

  302. 302. NURSING PRIORITY <br />GOAL: To promote adequate respiratory function<br />Adequate O2 supply from the environment. <br />Man requires 21% of O2 from the environment in order to survive. <br />Deep breathing and coughing exercises. <br />To promote maximum lung expansion and to loosen mucous secretions. <br />Positioning. <br />The semi-fowler’s or high fowlers position promotes maximum lung expansion. <br />LUDY MAE B. NALZARO, RN, MN<br />212<br />
  303. 303. NURSING PRIORITY <br />Patent airway. <br />To promote gaseous exchange from the person and the environment. <br />Causes of airway obstruction: <br />mucus secretions<br />edema of airways<br />spasms of airways<br />foreign bodies. <br />Airway obstruction is characterized by noisy breathing. <br />Adequate hydration.<br />To maintain moisture of the mucus membrane lining the respiratory tract. This is necessary to prevent irritation and infection. <br />LUDY MAE B. NALZARO, RN, MN<br />213<br />
  304. 304. NURSING PRIORITY <br />Avoid environmental pollutants, alcohol and smoking. <br />These factors inhibit mucociliary function. <br />Chest physiotherapy (CPT)- percussion, vibration, and postural drainage (PVD). These procedures are dependent nursing function. <br />LUDY MAE B. NALZARO, RN, MN<br />214<br />
  305. 305. NURSING PRIORITY <br />Postural drainage <br />is expulsion of secretions various segments by gravity. <br />involves placing the client in different positions so that the area of the lung congestion will be in vertical position with the bronchus. This facilitates drainage by gravity. <br />LUDY MAE B. NALZARO, RN, MN<br />215<br />
  306. 306. NURSING PRIORITY <br />Steam inhalation <br />Purposes: <br />To liquefy mucous secretions <br />To warm and humidify air <br />To relieve edema of airways <br />To soothe irritated airways <br />To administer medications <br />LUDY MAE B. NALZARO, RN, MN<br />216<br />
  307. 307. NURSING PRIORITY <br />Coughing<br />single most effective measure to control respiratory secretions upward. <br />Deep breathing<br />expands the alveoli and mobilizes secretions. <br />Pursed lip breathing<br />Allows a gradual decline of pressure hence preventing lung collapse <br />LUDY MAE B. NALZARO, RN, MN<br />217<br />
