- Pt has LOC, then administer neuromuscular blocking agent
PROTECTION AND POSITIONING:
- Apply pressure over cricoid cartilage (minimizes likelihood of
vomiting and aspiration
PLACEMENT WITH PROOF
- Each attempt NOT to exceed 30 seconds, max of 3 attempts. Ventilate
pt 30-60 seconds between attempts.
- After intubation, inflate the cuff
- Confirm tube placement w/exhaled CO2 detector.
POSTINTUBATION MANAGEMENT:
- Secure ET tube
- Set ventilator settings
- Obtain Chest x-ray
- Continue to medicate
- Recheck VS and pulse oxtimetry

UPDATE
What is a Combitube? - ANSWER--A dual-lumen, dual-cuff airway that
can be placed blindly into the esophagus to establish an airway. If
inadvertently 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? - ANSWER--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 - ANSWER--Percutaneous transtracheal
ventilation. (temporary)
What is Surgical Cricothyrotomy? - ANSWER--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
