Applications
In surgery, suction is used to remove blood, saliva, other biological material and foreign detritus from an anatomical passage or from a working field. A suction-irrigator can simultaneously perfuse and collect a saline solution where washing is required.
Suction is indispensable to clear the airway of blood, mucous, vomitus or other obstructing material. Consequently, suction machines can be found in emergency rooms, ambulances, patient wards and cafeterias.
A central vacuum pump connected to a building-wide network of suction plumbing is termed a "house vacuum". This is an efficient alternative to multiple small machines distributed throughout the building. Nevertheless the individual machines are necessary for mobile use and for backup during failure of a house vacuum.
