DH 410 – EMERGENCIES IN DENTAL PRACTICE Lecture 3: Emergency Oxygen Administration WLAC OXYGEN - LOCATION  BACK of MSB CLINIC  Across from the radiology bay  Against the wall Oxygen = GREEN Portable size-E Oxygen Cylinder  Oxygen Administration  Needed when breathing is inadequate for keeping the blood saturated with oxygen  Oxygen Administration  In dental office usually supplied by portable O2 tank  GREEN in color  Several parts  Cylinder  Regulator  Flow meter Figure 4.2 Regulator for oxygen tank  Parts of O2 Tank  Cylinder  Various sizes  Size E recommended for dental office  30 minutes of oxygen  Regulator  Reducing valve and flow meter joined  Regulator allows for safe release of pressurized O2  Parts of O2 Tank  Flow meter  Dial that allows operator to determine amount of O2 delivered  Measured in liters/minute (L/min)  Amount determined by condition being treated, oxygen delivery device, lung capacity of patient  Nasal cannula  Non-rebreathing face mask  Bag mask  Types of Delivery Devices in Dental Office  Nasal cannula  Rests on patient’s upper lip  Prongs inserted into nasal passages  Looped around patient’s ears  Oxygen flow 1-6 liters/minute  Must be turned on prior to placement Placement of nasal cannula  Types of Delivery Devices in Dental Office  Non-rebreathing face mask  To provide extra oxygen (use of reservoir bag)  Placed over patient’s nose and mouth  Patient can place mask to reduce apprehension  Straps tightened around patient’s head  One way valve to prevent exhaled gas from mixing with oxygen in reservoir bag  One valve on exhalation port so room air does not enter mask  6-12 L/min (dependent on patient lung capacity / tidal volume) Placement of non-rebreather bag  Types of Delivery Devices in Dental Office  Bag mask  Used for respiratory arrest when patient needs complete oxygen delivery  Difficult to obtain leak-proof seal around face  Use 3rd, 4th, and 5th fingers on bony portion of mandible (E) and thumb and index finger on mask to obtain good seal  Two rescuers recommended  Take turns  Administers 8-12 L/minute  Depending on lung capacity  During ventilation should see chest rise – if not, reposition head to open airway and/or bag mask Placement of bag mask  Reference Malamed, S.
