Suction is the day-to-day term for the movement of gases or liquids along a pressure gradient with the implication that the movement occurs because the lower pressure pulls the gas or liquid. However, the forces acting in this case do not originate from just the lower pressure side, but also from the side of the higher pressure, as a reaction ...
Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [ 5 ]
Aspiration, the inhalation of fluid while drinking, a common symptom of dysphagia. Aspiration, the practice of pulling back on the plunger of a syringe prior to injecting medication. Aspiration pneumonia, a lung infection caused by pulmonary aspiration; Aspiration thrombectomy, embolectomy where a thrombus is removed by suction; Bone marrow ...
In many hospitals and other health facilities, suction is typically provided by suction regulators, connected to a central medical vacuum supply by way of a pipeline system. The plastic, rigid Yankauer suction tip is one type of tip that may be attached to a suction device. Another is the plastic, nonrigid French or whistle tip catheter.
A transparent suction cup The pressure on a suction cup, as exerted by collisions of gas molecules, holds the suction cup in contact with the surface. One cup suction lifter. A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial ...
External suction (previously referred to as active suction) is used to create a sub-atmospheric pressure at the tip of a catheter.As the atmospheric pressure is lower compared to the intrapleural pressure, the lack of external suction (which was previously referred to as passive suction) is used to drain air and fluids.

Potain's aspirator. A medical aspirator is a suction machine used to remove mucus, blood, and other bodily fluids from a patient.They can be used during surgical procedures but an operating theater is generally equipped with a central system of vacuum tubes. [1]
Nasal suction can be used at home in order to decrease nasal congestion and open the airways. [ 1 ] Inadequate oxygen supply to the tissue is one of the main concerns during severe bronchiolitis and oxygen saturation is often closely associated with both the need for hospitalization and continued length of hospital stay in children with ...
