Suctioning: Airway
Airway Management
Question | Answer |
---|---|
Suction | involves the application of negative pressure (vacuum) to the airways through a collecting tube |
Airway obstruction can be caused by | Retained secretions Foreign bodies Structural changes |
Retained secretions | Increase work of breathing Increase airway resistance |
Retained secretions also | Hypoxemia -Hypercapnia -Atelectasis -Infection |
Suctioning can be performed in either | The upper airway (oropharynx) The lower airway (trachea and bronchi) |
Suction pressures | Infant: -80 to -100 mmHg Child: -100 to -120 mmHg Adult: -120 to -150 mmHg |
Catheter Size “Rule of Thumb” | estimate the proper size of suction catheter to use with a given tracheal tube, first multiply the tube’s inner diameter by 2 then use the next smallest size catheter |
