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.

The third chamber is the suction control chamber. The height of the water in this chamber regulates the negative pressure applied to the system. A gentle bubbling through the water column minimizes evaporation of the fluid and indicates that the suction is being regulated to the height of the water column.
Negative pressure wound therapy device Negative-pressure wound therapy ( NPWT ), also known as a vacuum assisted closure ( VAC ), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns .
In non-emergency situations, intermittent suction is often applied giving the benefits of suction without the untoward effects of damage to the stomach lining. [4] Suction drainage is also used for patients who have undergone a pneumonectomy in order to prevent anesthesia-related vomiting and possible aspiration of any stomach contents. Such ...
A Wangensteen suction apparatus is a modified siphon that maintains constant negative pressure. Used on a duodenal tube, it relieves gastric and intestinal distention caused by the retention of fluid. [ 1 ]
Anyway, when the choking patient is oneself, one of the more reliable options is the usage of any specific anti-choking device. In adults, there is limited evidence that the head down position can be used for self-treatment of suffocation and appears to be an option only if other maneuvers do not work. [7]
In refrigeration and air conditioning systems, the suction pressure' (also called the low-side pressure) is the intake pressure generated by the system compressor while operating. The suction pressure, along with the suction temperature the wet bulb temperature of the discharge air are used to determine the correct refrigerant charge in a system.
Cricoid pressure, also known as the Sellick manoeuvre or Sellick maneuver, is a technique used in endotracheal intubation to try to reduce the risk of regurgitation. The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it.
