airway suctioning
suctioning
[suk´shun-ing]Another complication arising from improper tracheal suctioning is hypoxia, which occurs when prolonged suctioning removes the oxygen from the patient's airway and thus adds to existing respiratory distress. The use of a catheter too large in diameter can cause obstruction of the bronchus and subsequent collapse of a lobe of the lung. Because of the potential hazards inherent in the procedure, tracheal suctioning should be reserved only for those patients too weak and debilitated to cough up thick and tenacious sputum. When deep suctioning is necessary, it should be done only by those persons who are skillful in the technique and knowledgeable about the complications that can result from improper use of the suctioning equipment. Guidelines for suctioning patients in either acute care settings or the home have been published by the American Association for Respiratory Care and are available on their web site at http://www.aarc.org.
