Airway Ultrasound — Flashcards

Flashcard 1: Which condition is characterized by a capnograph trace showing either a flat line or small CO2 peaks that rapidly decrease in height immediately following intubation?

Answer: Esophageal intubation

Extra: In esophageal intubation, the capnograph typically shows a flat line (no CO2). If CO2 was forced into the stomach during bag-mask ventilation, small waveforms may be seen initially, but these will rapidly decrease in height and disappear within a few breaths.

Flashcard 2: A _____mm endotracheal tube and laryngoscopy blade of size _____ are used to intubate a preterm infant

Answer: 3; 0

Flashcard 3: For cervicothoracic or stellate block, the most commonly used approach is the _____ technique.

Answer: paratracheal

Flashcard 4: Which condition is characterized by a 'shark-fin' appearance on a capnography waveform?

Answer: Bronchospasm (e.g., Asthma, COPD)

Flashcard 5: _____ with direct visualization is the first choice for definitive airway management in caustic ingestion

Answer: Oral intubation

Flashcard 6: _____ is a technique of external laryngeal manipulation of the airway during intubation for better visualization of the larynx.

Answer: BURP
