When using a video laryngoscope (e.g., GlideScope), the provider achieves an excellent view of the glottis but cannot pass the tube. What is the MOST common reason?
Answer: Tube is not directed anteriorly to match the blade's curve
Video laryngoscopy provides a hyperangulated view requiring the tube to be directed anteriorly along the blade's curve; failure to angle the tube appropriately is the most common cause of tube delivery failure.
A patient with suspected C-spine injury requires intubation. Which technique is PREFERRED to minimize cervical spine movement?
Answer: Video laryngoscopy with manual in-line stabilization
Video laryngoscopy with manual in-line stabilization is preferred as it achieves intubation with less cervical spine movement than direct laryngoscopy while maintaining spinal precautions.
The King LT airway is inserted with the patient's head in neutral position. After inflation of both cuffs, you ventilate but feel high resistance and see poor chest rise. What is the MOST likely problem?
Answer: The tube is advanced too deep, obstructing the laryngeal opening
If the King LT is inserted too deeply, the distal tip can pass beyond the glottis into the trachea or occlude the laryngeal inlet, causing high resistance and poor ventilation.
Which tidal volume setting is recommended for lung-protective ventilation in an intubated adult patient?
Answer: 6-8 mL/kg of ideal body weight
Lung-protective ventilation uses 6-8 mL/kg of ideal body weight to minimize volutrauma and barotrauma, particularly in ARDS and acute lung injury.
A patient with severe asthma is intubated. Ventilator peak airway pressures are 60 cmH2O and rising. Which ventilator adjustment is MOST appropriate?
Answer: Decrease respiratory rate and increase expiratory time
In obstructive disease, decreasing the respiratory rate and allowing more time for exhalation prevents auto-PEEP and reduces the risk of breath stacking and barotrauma.
Which of the following is an absolute contraindication to nasotracheal intubation?
Answer: Suspected basilar skull fracture
Basilar skull fracture is an absolute contraindication to nasotracheal intubation because the tube can be inadvertently passed into the cranial vault through the fractured cribriform plate.
You are managing a pediatric patient with croup and increasing stridor. After high-humidity oxygen and nebulized epinephrine, the child's condition worsens. What is the NEXT intervention?
Answer: Immediate orotracheal intubation with a tube 0.5-1 mm smaller than calculated
When medical management of croup fails, intubation with a tube 0.5-1 mm smaller than age-calculated size accommodates subglottic edema and reduces post-intubation complications.
