Coniotomy

A cricothyrotomy is a medical procedure where an opening is created through the cricothyroid membrane to establish a patent airway during emergency airway management. Cricothyrotomy is primarily performed as the last step in airway management algorithms in cases where an airway cannot be established by other means of nasal or oral tracheal intubation. These situations, often referred to as "cannot intubate, cannot ventilate" (CICV) or "cannot intubate, cannot oxygenate" (CICO), are commonly seen as a result of airway obstruction, angioedema, trauma, burns, or abnormal anatomy.
