What is a Combitube? - CORRECT ANSWERS A dual-lumen, dual-cuff airway

placed into trachea, it can be used as a temporary ET tube. There are only two
sizes: small adult and larger adult.
What is a Laryngeal Mask Airway? - CORRECT ANSWERS Looks like an ET
tube but is equipped with an inflatable, elliptical, silicone rubber collar at the distal
end. It is designed to cover the supraglottic area.
ILMA, does not require laryngoscopy and visualization of the chords.
What is Needle Cricothyrotomy - CORRECT ANSWERS Percutaneous
transtracheal ventilation. (temporary)
Complications include:
- inadequate ventilation causing hypoxia
- hematoma formation
- esophageal perforation
- aspiration
- thyroid perforation
- subcutaneous emphysema
What is Surgical Cricothyrotomy? - CORRECT ANSWERS Making an incision
in cricothyroid membrane and placing a cuffed endo or trach tube into trachea. This
is indicated when other methods of airway management have failed and pt cannot
be adequately ventilated and oxygenated.
Complications include:
- Aspiration
- Hemorrhage or hematoma formation or both
- Lac to trachea or esophagus
