Cricothyrotomy and transtracheal jet ventilation.
The escape of gas under highpressure caused the edges of the glottis to flutter, allowing recognition of the glottisand thereby assisting in intubation.

Percutaneous transtracheal jet ventilation. The pediatric airway has a smallerdiameter with greater resistance to gas flow according to the formula RN 1O lumenradius ,4 where R is airway resistance. Comparison of cricotiroisotomia pediatric and adult airway anatomy. Mace, MD, and J. Management of the difficult and failed airway. A ventilation bag setup is not recommended for adults because of difficulty intechnically providing an adequate tidal volume while allowing cricotrioidotomia time for exha-lation.
However, the exact age pincion which a needlecricothyrotomy rather than a surgical cricothyrotomy is indicated is a matter of debate. The syringe should be as-pirated when the needle is advanced.

An evaluation of cannula and oxygen sourcesfor pediatric jet ventilation. PEDIATRIC VERSUS ADULTCompared with the adult anatomy, the pediatric airway has a smaller in absolute sizeand proportionally cricothyroid membrane, greater overlap between the thyroid car-tilage and cricoid cartilage with less accessibility to the narrower slit-like cricothyroidmembrane, and smaller comparatively underdeveloped funnel or conical-shapedairway verses the larger, more cylindric-shaped adult airway.

The role of surgical cricothyrotomy revisited. Placing the catheter in thesubcutaneous tissue can cause massive subcutaneous emphysema, and thereforesome clinicians suggest performing a test of oxygen with a resuscitation bag ora low psi before administering the full 50 psi in an adult or 25 to 35 psi in a pediatricpatient to determine if the catheter is incorrectly placed and limit the amount of sub-cutaneous emphysema.
Before the catheter is secured, the hub should be held flushagainst the skin to avoid any air leaks.
