Optional, AEMT
2
Course Objectives Describe Sellick’s maneuver and the use of cricoid pressure during intubation. Describe the necessary equipment needed to perform orotracheal intubation. Describe the indications, advantages, disadvantages, and complications of orotracheal intubation. Describe the visual landmarks for direct laryngoscopy.
3
Course Objectives Describe steps to perform orotracheal intubation. Describe the methods of assessing, confirming, and securing correct placement of an orotracheal tube. Describe the technique for extubation.
4
Sellick’s Maneuver Helps prevent regurgitation and reduces gastric distention. Locate the cricoid cartilage by palpating the thyroid cartilage and the feel the depression just below it (cricothyroid membrane). Using your thumb and index finger of one hand, apply pressure to the anterior and lateral aspects of the cricoid cartilage just next to the midline. See picture on next slide.

14
Endotracheal Tube 5.0 mm-9.0 mm (cuffed) Distal end has a beveled tip for smooth movement through airway passages. Length ranges from 12cm- 32cm. Typical size for an average adult male is 7.5-8.5 mm Typical size for an average adult female is 7.0-8.0 mm

20
Oraltracheal Intubation Indicators Respiratory or cardiac arrest Unconsciousness Risk of aspiration Obstruction due to foreign bodies, trauma, burns, or anaphylaxis Respiratory extremis due to disease Pneumothorax, hemothorax, hemopneumothorax with respiratory difficulty
21
Advantages of Oraltracheal Intubation Isolates trachea and permits complete control of airway Impedes gastric distention Eliminates need to maintain a mask seal Offers direct route for suctioning Permits administration of some medications
22
Disadvantages of Endotracheal Intubation Requires considerable training and experience Requires specialized equipment Requires direct visualization of vocal cords Bypasses upper airway’s functions of warming, filtering, and humidifying the inhaled air
23
Complications of Oraltracheal Intubation Equipment malfunction Teeth breakage and soft tissue lacerations Hypoxia Esophageal intubation Endobronchial intubation Tension pneumothorax
24
Visual Landmarks
25
Hyperventilate the patient
26
Prepare and Test Equipment
27
Apply Sellick’s maneuver and insert laryngoscope
28
Visualize glottis through laryngoscopy
29
Inflate cuff, ventilate, and auscultate
30
Confirm placement with an ETCO 2 detector
31
Secure tube
32
Reconfirm tube placement
33
Field Extubation Prepare intubation equipment and suction Confirm patient responsiveness Suction the patient’s oropharynx Deflate the cuff Remove the tube upon cough or expiration Provide supplemental oxygen as needed Reassess the adequacy of the patient’s ventilation and oxygenation
34
Summary Sellick’s manuever Necessary equipment to perform orotracheal intubation Indications, advantages, disadvantages, and complications of orotracheal intubation Visual landmarks Steps to perform orotracheal intubation Methods of assessing, confirming, and securing correct placement of an orotracheal tube Technique for extubation
