Laryngeal Exposure Tube DeliveryAirTraqThe AirTraq Optical Laryngoscope marries the imaging system and the tube delivery mechanism, unlike the Glidescope, or McGrath video laryngoscopes---where tube is free handed to the target under vision. On the AirTraq the tube is positioned in the track on the right side. There is also a small bump on the right side of the tube track. The leading edge the tube tends to go slightly to the left of the center of the visual frame. This can cause the tip of the tube to hit the left side of the laryngeal inlet (either the aryepiglottic fold or posterior cartilages). Turning the AirTraq slightly rightward, by positioning the glottic opening slightly to the left of center in the imaging window, can improve insertion. If the tube tip is hitting too low that the lifting force upward on the device should be increased, so the tube trajectory is higher.
Like the Glidescope, McGrath and other imaging devices, the AirTraq provides a right-angled view around the tongue. Tracheal tubes that follow such a sharp bend around the tongue can have mechanical problems advancing into the trachea. This results from the sharp curve of the tube causing the leading tip of the tube to catch on the anterior tracheal rings. When a standard (left-facing bevel, asymmetrical tip) endotracheal tube is used, it helps to clockwise (rotate rightward) the tracheal tube off the AirTraq, as the tube is advanced. This will cause the bevel of the tube to face upward and is less likely to cause the leading edge to catch on the anterior tracheal rings.
This not only helps with insertion into the glottis because the tip is centered, but also minimizes any impaction on the anterior tracheal rings as the tube is advanced. Glidescope |

A helpful adjunct with the AirTraq, (and true also of other right angle imaging devices, i.e., GLidescope, McGrath, etc.) is to use a Parker tube that has a ski-tip shaped, symmetric tip design.Copyright 2011 Airway Cam Technologies, Inc. All Rights Reserved.
