The education and training goals in airway point-of-care ultrasound (POCUS) following an Indication, Acquisition, Interpretation, and Medical decision-making framework

Education/training goals in airway POCUSOptimal learning tool
Indications and background knowledge
(may be pre-existing)
Basic physics of ultrasound
Anatomy/sonoanatomy of the Airway
Indications of airway POCUS:
Aid in the location of:
  • The cricothyroid membrane

  • The cricoid cartilage

  • The tracheal rings

Confirmation of:
  • Orogastric or nasogastric tube placement

  • Correct endotracheal tube placement

Image acquisitionErgonomics
Transducer selection
Scan in transverse and sagittal planes
Patient positioned with the neck extended
Identify relevant anatomy
  • Thyroid cartilage

  • Vocal cords

  • Cricothyroid membrane

  • Cricoid cartilage

  • Hyoid

  • Tracheal rings

  • Esophagus

  • Thyroid gland

  • Surrounding vasculature

Hands on training
Image interpretationLocate and identify cricothyroid membrane Locate and identify cricoid cartilage
Locate and identify tracheal rings
Confirmation of the esophageal location of orogastric or nasogastric tube
Confirmation of intratracheal and excluding esophageal tracheal tube placement
Hands on training
Medical decision-makingImage the cricothyroid membrane in longitudinal and transverse planes and mark the skin for the correct location of emergent cricothyrotomy
Determine and mark the skin for the correct location of cricoid force (pressure)
Determine the safe utilization of an orogastric or nasogastric tube for gastric decompression or feeding
Determine the safe utilization of a tracheal tube for ventilation
