Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Tube thoracostomy (chest tube placement) is a procedure during which a hollow tube is inserted into the thoracic cavity for drainage of fluid or air. Emergency chest tube insertion is performed for definitive treatment of tension pneumothorax, traumatic hemothorax, large-volume pleural effusions, and empyemas. Irrespective of the cause of air and fluid accumulation in the pleural space, the...

We present a simple and efficient protocol for the generation of human macrophages. Buffy coats are processed by double density gradient centrifugation and isolated monocytes are then differentiated to macrophages in Teflon-coated cell culture bags. This maximizes macrophage yields and facilitates cell harvesting for subsequent experiments.

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used as energy sources to produce...

The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

Endotracheal Tube Extubation

2025
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support. Procedure Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
FAQs
PTFE has low surface energy, so many adhesives do not wet or bond reliably to its surface. This makes adhesive-only attachment vulnerable to poor sealing or disconnection. Mechanical approaches, including compression against a fitting or use of a ferrule, create the seal without depending on chemical adhesion and preserve PTFE’s resistance to many substances.
A compression fitting or ferrule presses the tubing against a connector, creating contact that restricts fluid or gas escape. The seal depends on appropriate compatibility between the tube and fitting and on secure assembly. In bioengineering circuits, this mechanical interface helps maintain stable transport while reducing risks of leaks, flow disruption, and accidental separation.
These components provide different mechanical routes for securing PTFE tubing to fluidic hardware. Ferrules support compression around the tube, while threaded adapters connect the tubing interface to components with matching threads. Compatible fittings are important because the connection must hold the tube firmly and seal against it without undermining PTFE’s chemical-resistance advantages.
Reliability depends on how securely the fitting seals the tubing and whether the selected components are compatible with one another. An inadequate interface can permit leakage, introduce flow disruption, or allow disconnection during operation. A well-matched mechanical connection supports controlled transport and helps maintain clean, stable fluid handling in the surrounding system.
Assembly begins by selecting a compatible fitting or adapter for the PTFE tubing and the receiving fluidic component. The tube is then positioned so the connector can seal against it, using a ferrule, compression mechanism, or threaded interface as appropriate. The completed joint should support secure transport without leakage, contamination, or unintended disconnection.
They are useful when a system requires chemically resistant tubing together with dependable transport of gases or liquids. Relevant settings include perfusion circuits, microfluidic devices, bioreactors, sampling lines, and laboratory instruments. In each case, the connection supports controlled movement through the system while helping preserve fluidic stability and reduce contamination-related problems.
A poor assembly can allow leaks, contaminate the fluid path, interrupt or alter flow, or permit the tube to disconnect accidentally. These failures may compromise operation of perfusion circuits, bioreactors, microfluidic devices, or sampling lines. Securely sealing the tube against its connector therefore contributes directly to stable, controlled fluid handling and reliable experimental performance.
