suzione

Suzione is the act or process of suction, drawing a fluid or gas into a space by creating negative pressure. The term is used in Italian and in technical English to describe a broad set of methods and devices that move material by suction. In general, suzione refers to lowering the internal pressure of a channel or vessel so that surrounding material is drawn in.

In medical contexts, suction is used to clear secretions from airways, remove fluids during procedures, and assist with wound drainage or diagnostic sampling. Dental practices employ suction systems to keep the oral cavity free of saliva and debris during treatment. In hospitalized patients, suction devices are used under controlled conditions to minimize risks of mucosal injury or infection.

In industry and laboratories, suction powers the movement of liquids and gases in pumps, vacuum systems, filtration setups, and chemical processing. Household uses include non-medical vacuum devices for cleaning or sample collection in hobbyist applications.

Mechanism and equipment: suction relies on creating a pressure difference between a conduit and its surroundings, achieved with manual or powered devices. Equipment ranges from hand-held syringes and bulbs to large industrial vacuum pumps and clinic-grade suction units, often with sterile, disposable tips for medical use.

Safety and regulation: improper suction can cause tissue injury, hypoxia, or contamination. Medical suction requires appropriate controls, sterile consumables, and adherence to infection-control guidelines and device maintenance.

Etymology: suzione derives from Latin suctio, via the verb sugere, meaning to suck. Notable related terms include suction, aspiration, and vacuum.
