W2 - Basic Endotracheal Intubation Flashcards
Identify the following structures:
- Epiglottis
- Aryepiglottic fold
- Cuneiform tubercles
- Corniculate tubercles
- Interarytenoid incisure
- Vocal cords
- Ventricular Folds
What is the laryngeal position in the neck?
Between the pharynx and the trachea
When are the vocal cords in the midline position?
When phonation is occuring or during effort closure
When are the vocal cords in the paramedian position?
During rest or at the end of expiration
When are the voal corde in the intermediate position?
During inspiration and depending on the depth of the breath
When are the vocal cords in the lateral position?
Diring maximum inspiration (a very deep breath)
What is the correct patient positional height and what are the two safety reasons for that height?
- The patient should be at the endoscopist’s waist level
- This height puts the endoscopist’s arm in the horizontal position, minimizing the energy consumption
- This height increases the enfoscopist’s visual depth of field (stand up straight!)
What three axies must be aligned to create a straight visual line to the vocal cords?
Laryngeal, Pharyngeal, and Oral
What are the three maneuvers to bring the laryngeal, pharyngeal, and oral axes in line?
Folded sheets under the head, atlanto-occipital extension (tilting the head back), and using the laryngoscope
What is the most common error leading to failure to obtain a direct view of the glottis?
Failure to use the folded sheets correctly
What are the five methods of confirming intibation?
- Feel the compliance of the anesthesis resevoir bag
- Observe the chest rise and fall
- Observe condensation in the face mask
- Observe the capnogram
- Auscultate the chest
What is the most highly reliable method of confirming ETT placement?
Capnography
What is auscultating the chest most useful for?
Determining that both lungs are being properly ventilated
