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.
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 ]
An eponymous disease is a disease, disorder, condition, or syndrome named after a person, usually the physician or other health care professional who first identified the disease; less commonly, a patient who had the disease; rarely, a literary character who exhibited signs of the disease or an actor or subject of an allusion, as characteristics associated with them were suggestive of symptoms ...
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 ...
NPPE develops as a result of significant negative pressure generated in the chest cavity by inspiration against an upper airway obstruction. These negative pressures in the chest lead to increase venous supply to the right side of the heart while simultaneously creating more resistance for the left side of the heart to supply blood to the rest of the body ().

Treatment is typically with antibiotics such as clindamycin, meropenem, ampicillin/sulbactam, or moxifloxacin. [1] For those with only chemical pneumonitis, antibiotics are not typically required. [2] Among people hospitalized with pneumonia, about 10% are due to aspiration. [1] It occurs more often in older people, especially those in nursing ...
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.
