Sucking out the Obstructions - With Suction Machines

The establishment of a clear airway is a vital part of basic life support and there are mechanical devices which are available to assist the clearance of the upper airway during resuscitation or recovering. Aspirators or suction machines are designed to expel obstructive secretions, gas, liquids (e.g., blood), and foreign bodies from the trachea and/or bronchial tubes. These devices usually consist of:

  • a powered or (less frequently) manual vacuum pump
  • a pressure regulator and a gauge
  • a number of collection canisters
  • Some plastic tubes connecting the components to each other
  • An overflow protection and/or bacteria filter
  • An endotracheal tube which is usually attached to the aspirator.

Tracheal suction machines are mostly portable and are battery powered. The basic vacuum level is from 80 mm Hg to 120 mm Hg which is maintained to reduce the risk of trauma. They are used to remove secretions and to maintain the airway of a patient; they are mainly used when suction from a central vacuum system is not available or is inappropriate.
