<SPAN style="FONT-FAMILY: Verdana,sans-serif; FONT-SIZE: 10pt">Suctioning is required to remove blood or other fluids from the surgical or dental operative fields or body cavities. A number of types of suction tips are available. When the tip is attached to a suction machine via&nbsp;polyethylene suction tubing, the tip is used to clear debris and fluid from the surgical field. Suction is used wherever and whenever a surgeon must remove fluid or debris that is obstructing his or her view of the surgical anatomy. &nbsp;</SPAN>
