Advanced Airway

"Describe the rationale for performing endotracheal intubation."

"Endotracheal intubation provides assistance to a patient in maintaining a patent airway, bypasses anatomic obstructions to clear airflow, and allows for direct suctioning of the lower airways."

"Identify the indications for endotracheal intubation."

"Indications include loss of ability to maintain a patent airway, risk of inadequate ventilation, airway edema, decreasing level of consciousness, and respiratory failure."

"Explain the contraindications for endotracheal intubation."

"Contraindications include laryngeal disruption, which involves structural damage or tearing of the larynx due to trauma."

"Describe common complications associated with endotracheal intubation."

"Common complications include oropharyngeal structural damage, laryngeal structural damage, and perforations of the esophagus or trachea."

"How does endotracheal intubation assist in airway management?"

"It assists by providing a direct means to maintain a patent airway and allows for suctioning of secretions and foreign materials."

"Define oropharyngeal structural damage in the context of intubation."

"Oropharyngeal structural damage refers to traumatic injury to the lips, teeth, tongue, and tonsillar pillars during the insertion of the laryngoscope."

"What is laryngeal structural damage and how can it occur during intubation?"

"Laryngeal structural damage involves injury to the epiglottis, laryngeal cartilages, airway mucosa, and vocal cords, often resulting from improper intubation techniques."

"How can perforations occur during endotracheal intubation?"

"Perforations can occur due to misdirected passage of the tube or stylet, leading to injury of the esophagus or trachea."

"Describe the potential complications associated with nervous and vascular injury during intubation."

"Vocal cord paralysis and bleeding are potential complications that can arise from nervous and vascular injury during intubation."

"Explain the significance of secondary traumatic injuries in the context of intubation."

"Secondary traumatic injuries such as cervical spine injuries and ocular injuries can occur, especially if proper immobilization is not maintained when trauma is suspected."

"Define the anatomical structures involved in endotracheal intubation."

"The anatomical structures include the mouth/oral cavity, pharynx (nasopharynx, oropharynx, hypopharynx), larynx (epiglottis, laryngeal cartilages, vocal cords), and trachea."

"How does the positioning of a patient affect the intubation process?"

"The patient is placed flat/supine with the head in the 'sniffing' position to align the oral, pharyngeal, and laryngeal axes for optimal visualization of the vocal cords."

"Describe the cervical spine exception during intubation."

"If a cervical spine injury is suspected, the sniffing position is avoided, and the patient is maintained in an appropriate cervical immobilization system."

"Explain the purpose of airway assessment prior to intubation."

"Airway assessment is conducted to evaluate anatomical visibility using the modified Mallampati classification, which helps determine the ease of intubation."

"Define the modified Mallampati classification and its relevance to intubation."

"The modified Mallampati classification assesses airway visibility: Class I shows soft palate, uvula, and pillars visible; Class II shows soft palate and uvula visible, indicating potential intubation difficulty."

"Describe the role of the larynx in the intubation process."

"The larynx contains the epiglottis, laryngeal cartilages, and vocal cords, which must be manipulated during orotracheal intubation to expose the airway."

"Explain the importance of careful movement of the tongue during orotracheal intubation."

"Careful movement of the tongue is crucial to elevate the epiglottis and directly expose the larynx and vocal cords, facilitating successful intubation."

"What anatomical structures are included in the oral cavity relevant to intubation?"

"The oral cavity includes the lips, teeth, tongue, hard palate, soft palate, uvula, gums, tonsils, and tonsillar pillars."

"Describe the visibility of the soft palate and uvula in Class III of the Mallampati classification."

"In Class III, the soft palate and base of the uvula are visible."

"Explain the proper use of a laryngoscope during endotracheal intubation."

"The laryngoscope is held in the left hand, inserted from right to left into the mouth to sweep the tongue and visualize the vocal cords."

"Define the components of a tracheal tube (Endotracheal Tube / ETT)."

"The ETT features a flexible tube with an inflatable cuff balloon at the distal end, a 15-mm adapter at the proximal end, a pilot balloon, and a distal Murphy eye."

"How is a stylet used in the context of endotracheal intubation?"

"The stylet, a malleable metal or plastic rod, is inserted into the tracheal tube to provide structural rigidity and shape, facilitating passage toward the laryngeal inlet."

"What is the purpose of a 10-mL syringe in endotracheal intubation?"

"The syringe is attached to the pilot balloon valve to inflate the distal cuff bulb with air after tube placement, sealing the trachea."

"Describe the role of lubrication in the endotracheal intubation process."

"Lubrication is applied to the tube and stylet to reduce friction and minimize tissue trauma during placement."

"Explain the importance of suction equipment during endotracheal intubation."

"Suction equipment is kept close by to clear secretions, blood, or vomit from the pharynx, maintaining a clear view of the vocal cords."

"How does a carbon dioxide detector assist in confirming endotracheal tube placement?"

"The carbon dioxide detector, either colorimetric or continuous capnography, is attached to the tube adapter to detect exhaled carbon dioxide, verifying proper placement."

"What is the function of a stethoscope in the context of confirming endotracheal intubation?"

"The stethoscope is placed on the chest to auscultate bilateral breath sounds and confirm equal air movement in both lung fields."

"Identify the types of laryngoscope blades used in endotracheal intubation."

"The types of laryngoscope blades include Macintosh (curved) and Miller (straight) blades, as well as video laryngoscopes."

"Describe the proper use of a Bag-Valve-Mask (BVM) with an oxygen source."

"The BVM should be connected to a 100% oxygen source to pre-oxygenate the patient prior to intubation and to deliver manual ventilations after tube placement."

"Explain the importance of cuff inflation after endotracheal intubation."

"Immediately inflate the tube cuff with a syringe to ensure a proper seal and facilitate effective manual ventilation using a BVM."

"How should a physical assessment be conducted after endotracheal intubation?"

"Perform an immediate physical assessment by inspecting for symmetrical chest expansion and observing chest rise and fall."

"Define the auscultation process for verifying endotracheal tube placement."

"Auscultate over the bilateral chest to verify breath sounds; absence of air movement over one lung may indicate a right mainstem intubation."

"What does visual moisture indicate in the context of endotracheal intubation?"

"Visual moisture, or tube fogging, indicates that the airway is moist and functioning properly."

"How is carbon dioxide confirmation achieved after intubation?"

"Apply an end-tidal CO2 colorimetric monitor and continuously track CO2 levels using capnography to confirm proper tube placement."

"Explain the importance of securing the tracheal tube after intubation."

"Securing the tracheal tube firmly prevents displacement and ensures continued ventilation."

"Describe the process for definitive radiographic confirmation of tube placement."

"Obtain a Chest X-ray (CXR) to confirm the exact depth and placement of the endotracheal tube."

"What ongoing monitoring is required after endotracheal intubation?"

"Continuously monitor cardiac rhythm, respiratory status, and vital signs, and reassure the patient if they are awake and able to understand."

"List adjunct airway tools and monitoring equipment used in patient care."

"Adjunct airway tools include oropharyngeal, nasopharyngeal, or supraglottic (LMA) airways, along with IV access, resuscitative medications, and continuous vital sign monitoring equipment."
