What are the two primary components of King Vision?
- A.
Display, Blade
- B.
Battery, Blade
- C.
Battery, Display
Correct Answer
A. Display, BladeExplanation
The King Vision consists of two primary components: the display and the blade. The display is used to visualize the airway and guide the intubation process, while the blade is the instrument used to open the patient's mouth and provide a clear view of the airway. The battery is not a primary component of the King Vision, as it is necessary for powering the device but does not directly contribute to its functionality.Rate this question:

Can the blades be used like Miller and Macintosh blades?
- A.
Yes
- B.
No
Correct Answer
A. YesExplanation
The design of the King Vision blade allows either technique to be used successfully. We recommend starting with the Blade tip in the vallecula (Mac approach) to avoid going too deep, but the tip can also be placed under the epiglottis (Miller approach).

What are some of the key differences between the King Vision video laryngoscope blade and a direct laryngoscope blade?
- A.
The King Vision is a video laryngoscope that uses a digital camera to view the vocal cords indirectly by looking around the corner under the base of the tongue
- B.
Because the device is curved to approximate typical anatomy, manipulation of soft tissue should be less than what is typically required for direct laryngoscopy
- C.
Minor manipulation or lifting of soft tissue may be necessary and is acceptable
- D.
Although not its intended function, the King Vision Blade satisfies the lifting strength requirements when tested in accordance with the ISO 7376 standard for direct view laryngoscope blades
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
The King Vision video laryngoscope blade differs from a direct laryngoscope blade in several key ways. Firstly, the King Vision uses a digital camera to view the vocal cords indirectly by looking around the corner under the base of the tongue. This indirect view allows for a curved blade that approximates typical anatomy, resulting in less manipulation of soft tissue compared to direct laryngoscopy. However, minor manipulation or lifting of soft tissue may still be necessary and acceptable. Additionally, although not its intended function, the King Vision Blade meets the lifting strength requirements for direct view laryngoscope blades according to the ISO 7376 standard. Therefore, all of the above statements are true.Rate this question:

Inserting the Blade into the patient’s mouth is inhibited by the Display hitting the patient’s chest. There is nothing that can be done to avoid this.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
If possible, position the patient’s head and neck as you would for any normal intubation, including raising the shoulders and head for obese patients. Scissors the mouth open to gain space to introduce the Blade into the mouth. A lateral approach (like oropharyngeal airway insertion) can be employed with rotation back to the midline once the Blade tip has been advanced to the base of the tongue. In extreme cases, the Blade can be introduced separately followed by Display installation after the blade has been advanced into the posterior pharynx.Rate this question:

The Blade or channel should be lubricated before inserting an endotracheal tube.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Lubrication of the King Vision Blade and the endotracheal tube is recommended prior to use. With the Standard (non-channeled) Blade, lubricate the distal tip of the blade, taking care to avoid the lens, camera, and light assembly. The endotracheal tube should be lubricated in a normal manner. The Channeled Blade should be similarly lubricated, but its posterior aspect should also be lubricated since it may contact the posterior pharyngeal wall. Lubricate the endotracheal tube and ensure that it slides easily within the blade channel.Rate this question:
-
- 11.
Pre-loading the endotracheal tube in the Channeled Blade before placing the King Vision into the mouth is required.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
While not required, it is often advantageous to preload the endotracheal tube into the guiding channel of the Blade. Alternatively, the user may elect to place the lubricated endotracheal tube in the channel after the Blade is inserted into the patient’s mouth.Rate this question:
-
- 12.
The primary function of the soft material used on the Channeled Blade is to prevent damage to the patient's teeth.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The Channeled Blade is designed to guide the endotracheal tube to the vocal cords. The channeled portion of the Blade is comprised of a combination of a rigid plastic forming the support of the channel and a soft, over-molded portion comprising the outer edge and external lower portion of the channel. This soft, outer edge facilitates easy removal of the endotracheal tube from the Blade after placement and provides a soft posterior blade surface during insertion. No other channeled video laryngoscope has this feature.Rate this question:
-
- 13.
Overmolding is a feature of the channeled portion of the Blade. Overmolding allows for a supportive channel where strength is needed and a soft, smooth edge where pliability is required.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Overmolding is a manufacturing process that essentially combines materials (in this case with different performance characteristics) into one part without adhesives. This allows for a supportive channel where strength is needed and a soft, smooth edge where pliability is required.Rate this question:

When the Blade is attached, the device will power off after 90 seconds once placed on a non-moving surface.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
King Vision uses a sophisticated power management system that is designed to conserve power. It will automatically power off when the Blade is removed from the Display. With the Blade attached, it will power off after 60 seconds once placed on a non-moving surface due to an integral motion sensor. After power-on of the Display only (i.e., to check battery status), power-off occurs after 20 seconds.Rate this question:
-

A "snowy" image on the screen is a result of not attaching a Blade to the Display before powering on the device.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
No Blade was attached to the Display. The Display can be turned on prior to inserting a blade, but only for a battery life check. Because the camera is in the Blade and there is no Blade attached, the Display cannot provide an image. This results in a snowy screen. Turn off the display and attach a blade before powering on again. This will provide a functional image.Rate this question:

It is impossible to record an image displayed on the King Vision Display.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
You can record an image from the King Vision Display. It requires that you use the King Vision Cable to connect to a video capture device. The Cable is sold separately and is 9’ in length.Rate this question:
-
- 18.
The King Vision Cable is a standard connection and can be used to connect to any external monitor.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Although the video out on the King Vision Display appears to be a mini-USB connection, it is not a standard fitting in that only video out is permitted. Other cables, though they may appear to fit the small USB port, may damage the display or your monitor. This action also voids the warranty. The cable connects to the monitor using a standard RCA connector.Rate this question:

What type of batteries are included with the King Vision Display?
- A.
Alkaline
- B.
Lithium
Correct Answer
A. AlkalineExplanation
The King Vision comes with three alkaline batteries, factory packaged. Once installed, the portable, high density, closed-cell foam display carrying case has a storage location for extra batteries.Rate this question:
-
- 20.
Lithium batteries are not recommended for use with the King Vision.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
While lithium batteries generally last longer than standard alkaline batteries, the power curve with lithium falls off quickly. This rapid loss of power shortens the user’s time to respond at the end of the batteries’ life once the King Vision battery indicator light begins to flash red. The power stored in alkaline batteries is reduced more gradually, allowing sufficient time to finish a typical procedure prior to replacing the batteries. Replace the batteries prior to the next use.Rate this question:
-
- 21.
To check the battery strength, simply turn on the Display. It is not necessary to install a Blade to do this.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Simply turning the Display ON the battery indicator light will come on. The screen displays a static, snowy image because the camera (which is in the blade, not the display) is not attached. A green light indicates adequate battery life. A flashing red light or no image indicates that you should change the batteries before the next case.Rate this question:
-
- 22.
A new set of batteries should last roughly 60 minutes.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Under continuous use, three AAA batteries should last over 90 minutes. Your actual experience may vary based on a number of factors including, but not limited to; the age of the batteries, a number of on/off cycles, length of procedures, use of video output. Follow the battery manufacturer’s guidance on specific battery use.Rate this question:

OLED stands for Organic Light-Emitting Diode.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
OLED is short for organic light-emitting diode, a display device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass. Unlike LCDs, which require backlighting, OLED displays are emissive devices - they emit light rather than modulate transmitted or reflected light. It is beginning to replace LCD technology in handheld devices such as PDAs and cellular phones because the technology is brighter, thinner, faster and lighter than LCDs, uses less power, offers higher contrast and is less expensive to manufacture.Rate this question:
-
- 24.
CMOS stands for Complementary Metal Oxide Semiconductor.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Pronounced see-moss, CMOS is a widely used type of semiconductor. Short for complementary metal-oxide-semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices.Rate this question:
