About the Simulator

The Life/form® “Airway Larry” Airway Management Trainer Head is a realistic simulator available for the training of intubation and other airway management skills. The airway management trainer is anatomically correct in respect to both size and detail. Landmarks include nostrils, teeth, tongue, oral and nasal pharynx, larynx, cricoid ring, epiglottis, arytenoid, false and true vocal cords, trachea, and esophagus.

Nasco's “Airway Larry” allows you to practice oral, digital, and nasal intubation. E.T., E.O.A., P.T.L.®, L.M.A., E.G.T.A., Combitube®, and King System insertion can all be practiced as well (please see section titled “Using the Combitube®”). Suction techniques and proper cuff inflation can also be performed and evaluated.

In addition, this model also allows students to apply cricoid pressure during the intubation procedure (Sellick's Maneuver). By locating the larynx and depressing the cricoid ring, the student may realistically lower the vocal cords farther into the field of view. This also effectively closes off the esophagus of the simulator.

Install your new “Airway Larry” Airway Management Trainer Head to update any CPARLENE® manikins and torsos, use as a stand alone trainer, or as a replacement head for any Adult CRiSis™ manikins, torsos, or Airway Management Trainer with stand. With proper care, your Life/form® Airway Management Trainer will provide years of valuable service. Please review the instructions carefully for setup, cleanup, and maintenance procedures.

List of Components

Setup

The “Airway Larry” Airway Management Trainer Head is ready to use as a stand-alone trainer upon delivery. Simply remove it from the carton and unwrap the packaging material. Please note that lung and stomach bags are not included, but can be purchased separately. See Supplies and Replacement Parts for part numbers.

Lubrication

Before using the Airway Management Trainer, lubricate both the simulator and supplies being used with the Nasco lubricant provided. (See Figures 1 & 2.)

A. Intubating the Airway Management Trainer

Nasco recommends the use of a 7.5-8 mm endotracheal tube for oral intubation and 7.5 cm or smaller for nasal intubation. This simulator allows for the Sellick's Maneuver of applying cricoid pressure during intubation procedures. Ensuring the cuff is properly deflated prior to removal will prolong the useful life of your simulator. Damage caused by improper use of the simulator will not be covered under the warranty.

  1. Determine the method of intubation.
  2. Select the appropriate sized intubation appliance.
  3. Generously lubricate the airway and appliance.
  4. Intubate the manikin.
  5. Visualize chest rise or stomach inflation.
  6. Ensure the cuff is properly deflated before removing the appliance.
Note: Remove all appliances prior to storage.

B. Using the Combitube® (not included)

Thoroughly read and follow the instructions that come with the combitube. The trainer will accept either a full size or a small adult tube. As with a real patient, it may be necessary to back the tube out if ventilation cannot be established.

Note: Depending on tube placement, the large cuff may not accept the recommended amount of air. In this case, simply inflate the cuff to its maximum volume (when the plunger stops) and while holding the plunger down, detach the syringe from the blue print balloon and proceed.

C. Attaching the “Airway Larry” Airway Management Trainer Head to a Torso

Nasco's Airway Management Trainer has the ability to be attached to CPARLENE®, Adult CRiSis™ Torsos and Manikins, and Life/form® Airway Management Trainer Stands.

Care and Maintenance

A. General Cleaning

Normal surface soil can be removed from the trainer with mild soapy water. Do not allow water to contact electrical components. Stubborn stains may be removed with Nasco Cleaner (LF09919U). Simply apply the Nasco Cleaner to the soiled area and wipe clean with a soft cloth.

Note: Avoid using cleaner around the mouth area if students will be applying direct mouth-to-mouth resuscitation techniques, as the cleaner may be toxic if ingested.

B. Cleaning the Airway Management Trainer Head

  1. Remove the head from the torso or stand using the same methods previously described. Also remove the lungs and stomach.
  2. Take the trainer to an area with a sink and open counter space. Using the red caps supplied, plug the right and left bronchi and the esophagus.
  3. Stabilize the head on the counter face-up (towels work well for this) with plugged tubes hanging over the sink. (See Figure 14.)
  4. Carefully pour warm soapy water (a mild dish soap works best) into the mouth until the water level reaches halfway up the tongue.
  5. Tilt the head back and bring the neck up 3" off the countertop.
  6. Continue filling until the water level covers the tongue. Take a small soft brush and gently scrub the inside of the mouth (a small toothbrush works well for this). Cotton swabs can be used to scrub inside the nostrils.
  7. When done, pull the red cap from the esophagus and drain the water into the sink.
  8. Now pick the head up, hold it in a vertical position, and pull the caps from the bronchi to completely empty the system. (See Figure 15.)
  9. Figure 14 left image, Figure 15 right image

    Figure 14 (left image), Figure 15 (right image)

  10. Rinse the airway, following the same procedure used to clean, with warm tap water only. Repeat this process until all the soap has been flushed from the system.

C. Disinfecting the Airway

To disinfect, repeat the standard cleaning procedure with a bleach solution, as specified by the Centers for Disease Control.

  1. Fill the system with the solution until it reaches the corners of the mouth. Remember to start filling with the head flat and finish with the neck slightly elevated to ensure that the solution completely fills all airway passages.
  2. Once completely filled with the bleach solution, allow the head to sit for at least 10 minutes.
  3. Drain as previously described and repeat the rinsing process to flush out all of the bleach solution. Set the head aside and allow it to air dry completely prior to next use or storage.

Cautions

  • Do not place simulator in contact with any printed paper or plastic. The ink will transfer and cause an indelible stain. Similar inks, such as ball-point pen, will also cause an indelible stain.
  • Do not use Nasco Cleaner (LF09919U) around the nose or mouth of the simulator. The cleaner may be toxic if ingested.
  • Properly lubricate the Airway Management head and intubation appliances.
  • Use only Nasco Pump Spray Lubricant (LF03644U) with this simulator. Other lubricants, such as silicone oil, may cause damage to the airway of the simulator.
  • Ensure intubation appliances are used accordingly. Improper use of intubation appliances could damage the airway of the simulator. Damage to the airway will require the product to be returned to Nasco for repair.
