endotracheal tube locator - shown with magnet-tagged ET tube Penguin Endotracheal (ET) tubes are typically placed through the mouth into the trachea to ensure an unobstructed airway. ET tubes are placed by emergency personnel in the field or by a physician or nurse in an emergency or operating room. Problems with inserting ET tubes include esophogeal placement, and insertion too high or too low in the trachea - resulting in damage to the larynx (too high) or single-lung ventilation (too low).
"finding" magnet-tagged ET tube Penguin The detector is designed to quickly confirm proper tracheal placement of a magnet-tagged ET tube. The Penguin alerts the user when it has located the ET tube both visually (LED) and audibly (tone). - This device has not been cleared by the FDA - |
