1 SAN JOSE STATE UNIVERSITY School of Nursing Nursing 155 Artificial Airways and Mechanical Ventilation KEY Introduction This module is divided into four sections: Learning Resources, Independent Learning Activities, Skills Lab Activities, and Critical Thinking Activities. Most of the activities in this module may be completed at a time and place convenient for you, independently, with a partner, or in a study group. It is recommended that you complete each section of the module in the order in which it is listed. Learning Resources comprise a list of the resources available to you that pertain to the content of this module. It is not required that you review all the resources listed: choose those that best help you to complete the activities in the module, and that best suit your learning style. You may use other, credible sources of information as well; check with your instructor if you have questions about the usefulness of resources you locate. Keep in mind that you will most likely need to use multiple sources to find all the information you need. Independent Learning Activities should be completed before going into the Skills Lab to do the Lab Activities; they cover the theoretical information you need to know about the subject of this module. These activities are not turned in or graded. They are for your learning benefit. You can validate your answers with the answer key in the NLRC. Show your instructor your completed activities and your instructor will sign the first page. Show the NLRC helper your instructor’s signature to gain access to the key. MODULE KEYS MAY NOT BE COPIED OR REMOVED FROM THE NLRC Skills Lab Learning Activities must be completed in the lab. Practice multiple times to gain proficiency; you will be expected to perform the skills competently in your clinical courses during subsequent semesters. Critical Thinking Activities require that you apply the information you have learned. It is unlikely that you will find the answers to these questions in your Learning Resources. Feel free to discuss your answers with your Lab instructor. Exams: Any content in this module may be tested in any of several ways: written quiz or exam, lab exhibit, or practical demonstration.

Distinguish between pharyngeal and tracheal airways and their indications for use. 3. Describe the purpose of inflating a tracheal cuff. 4. Determine when a tracheal cuff should be deflated. 5. State maximum tracheal cuff pressure. 6. Discuss why it is important to check tracheal cuff pressures on tracheal airways. 7. Describe three important nursing interventions for the patient with an oropharyngeal or nasopharyngeal airway. 8. Describe five important assessments for the patient with an endotracheal tube. 9. Distinguish among nursing interventions for each of the four types of artificial airways. 10. List two reasons a patient may require mechanical ventilation. 11. List two complications related to the presence of tracheostomy. 12. list three benefits of tracheostomy as compared to ETT. 13. List three different alarms on a ventilator and the significance of each. 14. Identify two different modes of oxygen delivery for a patient with a tracheostomy. 15. Identify the purpose and procedure for sterile suctioning. 16. Identify the three types of airways through which the nurse can perform pulmonary suction. 17. State the maximum amount of time one can use to suction a patient from catheter passage to its removal. N155: Artificial Airway Key 4 Learning Activities 1. List two reasons a patient may require an artificial airway. a. Maintain an open airway in an unconscious patient or a patient with a diminished gag reflex b. Patient requiring frequent nasopharyngeal suctioning c.Aassist in ventilating a patient with absent or inadequate respirations 2. Complete the following table by briefly describing the anatomical locations and indications for use of two pharyngeal airways and two tracheal airways. Pharyngeal Airways Tracheal Airways 1._ Oropharyngeal 1. Endotracheal tube Anatomical location: Central portion of the pharynx Anatomical location: Trachea, via oral cavity. End of tube should sit 5 to 7 cm above carina in mainstem bronchus. Used for patient requiring mechanical ventilation. Indications for use: To maintain patent airway by keeping tongue from obstructing; used for unconscious pt w/absent or diminished gag reflex. 2. nasopharyngeal airway Indications for use: Respiratory arrest, surgery, cardiac arrest, trauma Anatomical location: Through nasal cavity to posterior pharynx 2. tracheostomy tube Anatomical location: Trachea, surgically inserted via anterior neck Indications for use: Indications for use: Same as oropharyngeal airway, but inserted via nares. Also used for patient requiring frequent suctioning. Long term mechanical ventilation (>21 days). 3. What is the purpose of inflating a tracheal cuff? Prevent air leak 4. What is the maximum tracheal cuff pressure? < 20 mmHg or < 25 cm H20 5. Why is it important to check cuff pressures on tracheal airways? Overinflation can cause necrosis of tracheal tissue N155: Artificial Airway Key 5 6. When is it appropriate to deflate a tracheal cuff? When a patient is being weaned from the ventilator, or when a tracheostomy is going to be plugged with a tracheostomy button or passey-muir valve, or the tracheostomy may be plugged for brief periods when the patient is learning to manage their own airway. In addition, the cuff may be deflated when the patient is learning to take food and fluid by mouth; keeping the cuff inflated may make swallowing more difficult. 7. What are three important nursing interventions for the patient with an oropharyngeal or nasopharyngeal airway? a. frequent oral care b. suction oral cavity and lungs as needed c. assessment of mucosa; prevent breakdown 8. What are five important assessments for the patient with an endotracheal tube? a. Breath sounds and respiratory rate b. Quality and quantity of secretions c. Temperature d. Condition of oral or nasal mucosa e. Ensure tube is taped securely and has not moved 9. Match the following nursing interventions with the type of airway each pertains to. More than one airway may apply per intervention. Airway Intervention a. Oropharyngeal ___d___ cleaning the inner cannula b. Nasopharyngeal __a,b,c,d_ sterile suctioning of lungs c. Endotracheal __a,b,c,d_ nonsterile oral suctioning d. Tracheostomy __a,b,c,d_ assess breath sounds __a,b,c,d assess quality and quantity of secretions ___a,b,c_ assess mucosa for breakdown ___d___ change dressing at insertion site N155: Artificial Airway Key 6 10. List two reasons a patient may require mechanical ventilation. a. Respiratory failure b. Shock c. Cardiac arrest d. Surgery e. Trauma f. Neuromuscular disorders 11. List two complications related to the presence of tracheostomy. a. Bleeding } most common b. Infection } most common c. Tube displacement d. Obstruction e. Cuff leakage f. Tracheal erosion g. Tracheoesophageal fistula h. Death 12. List three benefits of tracheostomy as compared to ETT. a. increases patient comfort b. spares further direct laryngeal injury c. improves patient’s ability to communicate d. facilitates oral intake of food, thus providing psychological benefit e. provides more secure airway and thus may facilitate ICU discharge f. decrease airway resistance and thus may aid weaning in patients with marginal lung function 13. List three different alarms on a ventilator and the significance of each. a. High respiratory rate significance: Client may have increased metabolic demand for oxygen; pain or anxiety. Need to assess client, calm and reassure her, evaluate ABG’s N155: Artificial Airway Key 7 b. Low inspiratory pressure significance: Tubing may be unattached, there may be a leak around tube, or tube may be displaced into pharynx or esophagus. Need to check if tubing attached and assess placement of tube c. High pressure limit significance: Possible airway obstruction, client fighting ventilator, or tubing kinked. Clear obstruction, unkink tubing or reassure/sedate client. 14. Identify two modes of oxygen delivery for a patient with a tracheostomy a. ventilator b. mist collar 15. Identify the three types of airways through which the nurse can perform pulmonary suction. a. nasopharyngeal b. endotracheal c. tracheostomy 16. What is the maximum amount of time one can use to suction a patient from catheter passage to its removal? 15 seconds N155: Artificial Airway Key
