Both blade versions slide over the video adapter and connect to the reusable display, completing the King
Vision aBlade Video Laryngoscope. The distal window of the blade has an anti-fog coating to prevent
condensation from affecting the image (Fig. 1, #10).
Blade sizing is intended to be consistent with standard rigid laryngoscopes. This means that the size 3
aBlades (both channeled and standard) should be considered for the same patient population as a
standard Macintosh size 3 blade. The aBlades size 1 and 2 should be considered for the same patient
population as a standard Macintosh or Miller size 0 to 2.
Size Selection
The King Vision aBlade system offers a complete range of video adapters and disposable blades for a wide
range of patients. Make sure that you select the video adapter and aBlade that is the best fit for your
patient.
For infants and children the small video adapter 1-2 and associated blades are indicated:
aBlade size 1 (Infant patients <4 years)*
aBlade size 2 + 2C (Child patients 1 – 10 years)*
For larger children and adults the large video adapter 3-4 and associated blades are indicated:
aBlade size 3 + 3C (Children > 5 years and Adults)*
*Size ranges are based on teeth-to-vallecula data for the given ages, tracheal tube sizing recommendations
and actual experience. A medical professional must evaluate on a patient-by-patient basis.
