USE OF ALL-IN-ONE AIRWAY STABILIZING DEVICE TO SECURE OXYGEN SUPPLEMENT DURING BRONCHOSCOPY

Abstract

SESSION TITLE: Tuesday Abstract Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/22/2019 01:00 PM - 02:00 PM PURPOSE: To guarantee the application of supplemental oxygen to supraglottic area and bypass any nasal or oral cavities hindrance. Oxygen supplement during moderate sedation prevents occurrence of clinically significant desaturation during endoscopic procedures. Providing oxygen via nasal cannula or face mask during bronchoscopy may not necessarily secure delivery of same amount of liter flow to the supraglottic area. The availability of higher amounts of oxygen in this anatomical site will secure oxygen supplement to lower levels of the airway with less work of breathing. Patients who require sedation may have less effort for breathing. Therefore, providing higher amounts of oxygen right above the vocal cords or to the supraglottic area will facilitate easier oxygen supplement to the lower levels of bronchial tree. Unforeseen nasal passages or oral cavity anatomical or pathological abnormalities, may hinder the adequate supplying of oxygen to lower levels of the bronchial tree. This unforeseen dilemma may cause intermittent or prolonged desaturations that require increasing oxygen flow to overcome those anatomical or pathological barriers. Deviated nasal septum, nasal polyps, large size tongue or redundant mucosal lining of upper airway passages constitute some of the examples for those anatomical or pathological dilemmas. The use of this All-In-One airway device is seeking stabilization of upper airway patency to allow supplying oxygen to the supraglottic area and, hence, the lower bronchial tree without having to refer to trans laryngeal intubation. The device is orally inserted. It consists of a tubular structure with a curvature to help depressing the tongue and create a passage for the fiber optic bronchoscope via the working channel. The device has a multi-functioning revolving valve that allows connection with different tubing systems to provide oxygen. The whole amount of oxygen provided through the oxygen side port will continue to flow through the tubular structure up to the level of vocal cords in the supraglottic area. The All-In-One airway stabilizing device has another side port that can connect to capnography equipments as desired while patients are sedated. METHODS: A comparison study between the All-In-One airway stabilizing device and mouth piece during bronchoscopy. Oxygen source was attached to the oxygen side port in the All-In-One airway stabilizing device in one arm of the study and a nasal cannula was provided to the other patient on the other arm of the study where the mouth piece was provided. RESULTS: Oxygen supplement source was more secured to provide higher flow of oxygen at the targeted anatomical location. CONCLUSIONS: The use of All-In-One airway stabilizing device will enable more guaranteed oxygen supplement to flow at the targeted anatomical locations. CLINICAL IMPLICATIONS: Use of All-In-One airway stabilizing device will secure oxygen supplement for sedated patients.
