b'Chapter hapterMaintaining the airwayOropharyngeal airwayAn oropharyngeal airway is a device used to assist in establishing and maintaining an adequate airway.It is normally used in association with a mechanical resuscitator or on an unconscious, breathing patient where there is difficulty maintaining an open airway.An oropharyngeal airway cannot be inserted on a semi-conscious patient as it can irritate the back of the throat and cause spasm and vomiting.Oropharyngeal Aspiration (Suction)A suction device (eg Yankauer sucker or flexible catheterY suction tube) is inserted to aspirate fluid (saliva, mucus, vomitus) from the mouth and nose to prevent inhalation and to maintain a clear and unobstructed airway.This can only be used on an unconscious patient. SuctionSuction assists with maintaining a clear and open airway by aspirating saliva, blood, mucous and foreign material.Suctioning can prevent pulmonary aspiration, which can lead to lung infections.Manual airway clearance is still necessary to remove solid matter or viscous mucous.A clear and open airway must be maintained during resuscitation.MethodPosition the patient preferably in the recovery positionManually clear / wipe away any solid matter or viscous mucous (use protective gloves)Carefully measure the suction catheter from the corner of the patients mouth to their ear lobe (this indicates correct depth of insertion).Do not insert beyond the back teeth.With the suction unit turned on, place the suction tip into the mouth (in and around the inside cheek area).Gently sweep the catheter across the lower cheek and aspirate for 5 seconds.Gently withdraw the catheter from the patients mouth (while still aspirating)Flush the line with water (place catheter into a bowl of water and suction through)Make sure the suction reservoir bottle does not over fill beyond 2/3.Switch the unit off after use.Note If the catheter is inserted too far, it can cause the patient to gag and vomit Ensure that suction is timed so there is no interference with the patients normal breathing / ventilationAdvanced Resuscitation 245'
