| Question | Answer |
| Laryngoscope | Handle
*Always held in the left hand
*Batteries for light |
| Types of Blades | Curved/McIntosh Blade
Straight/Miller Blade |
| Curved/ McIntosh | fits into the vallecula, indirectly raises epiglottis (Adult)
can't see vocal cords Advance Blade |
| Straight/Miller | fits directly under the epiglottis (Preferred for Infant) |
| Laryngoscope Troubleshoot: | If light doesn't work
* Tighten bulb
* Check handle attachment
* Change blade
* Change batteries |
| Blade Sizes | Adult: Size 3
Pediatric Size: 2
Term Infant: Size 1
Pre-Term: Size 0 |
| Stylet | Used to aid in ORAL intubation
Shapes the tube for easier insertion
End is to be recessed 1 cm above ET Tube |
| Magill Forceps | Used to aid in nasal intubation
Inserted in mouth to lift tube into trachea |
| Endotracheal Tubes
Tube Sizes Pre/Full Term Infants: | Preterm Infant 2.5- 3.0
Full-term Infant 3.0-3.5 |
| Endotracheal Tubes
Tube Sizes Adult: Male | wt in kg\ 10
8.0-9.0 |
| Endotracheal Tubes
Tube Sizes Adult: Female | 7.0-8.0 |
| Tube Markings | Oral Intubation: 21-25 cm mark at lip
Nasal Intubation: 26-29 cm mark at nare |
| Cuff Types | * High Pressure Low Volume, Low Compliance
* Low Pressure, High Volume, High Compliance, Floppy Cuff
* Cuff pressure should not exceed 20mmHg in order to allow circulation to the tracheal mucosa |
| Monitoring Cuff Pressure | Measured with a 3 way stopcock, syringe, pressure manometer
Cufflator: used to eliminate syringe, and manometer and stopcock cuff pressure should not exceed 25cmH20
If cuff reads 0 check connections |
| Endotracheal Tubes | Double- Lumen, Esophageal Tracheal Combitube, Laryngeal Mask Airway, Hi-Lo Evac Tubes |
| Double Lumen (Carlen's Tube)(DLT) | ET Tube with 2 independent lumens of different lengths
longer Tube: inserted in either the left or right main stem
shorter Tube: placed in the trachea above the carina |
| Double Lumen (Carlen's Tube)(DLT)2 | Each Lumen can ventilate one lung separately
or they can be connected via wye and share ventilation source |
| Indications for double lumen ETT | * Independent lung ventilation
* Lung Abscess Unilateral lung disease
* Pneumonectomy, Lobectomy, Esophageal Resection, Aortic * Aortic repair
* Bronchopleural Fistulas Trauma to 1 lung |
| Esophageal Tracheal Combitube
EMERGENCY TRANSPORT | * Option for emergency airway management
* placed blindly |
| Laryngeal Mask Airway
(LMA) | Positioned directly over the opening into the trachea (hypopharynx)
Intubate through the LMA Do Not Remove, Until Intubated |
| Hi-Lo Evac Tube | indicated for the use of oral or nasal endotracheal intubation
that requires continuous aspiration of subglottic secretions
continuous suction is provided via pilot tube connected to a vacuum 20mmHg |
| Hi-Lo Evac Tube Helps With: | Method used to reduce incidence of Ventilator Acquired |
