2023
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...

Uterine Tubes

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.

Tracheostomy: Procedure and Tubes
0 Views •
2025
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions. Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Rise of Liquid in a Capillary Tube
0 Views •
2023
When very thin cylindrical tubes, called capillaries, are dipped in a liquid, the liquid rises or falls in the tube compared to the surrounding liquid. This phenomenon is called capillary action. Capillary action occurs due to the combination of two opposing forces: the cohesive forces of the liquid, which cause it to stick to itself and form a rounded shape, and the adhesive forces between the liquid and the walls of the container, which cause the liquid to be attracted to the container walls.
FAQs
Tubing size and connection quality directly affect how consistently fluid moves through the setup. Selecting an appropriate size helps match the tubing to the experimental system, while compatible connections to a syringe, needle, or pump support controlled transfer. Poorly fitted connections can introduce leakage or flow variation, making infusion, sampling, and perfusion measurements less consistent.
Chemical resistance helps the tubing remain compatible with many experimental solutions during fluid transfer. This reduces concern that routine contact with the solution will compromise the tubing’s intended use in an experimental setup. Compatibility is especially relevant when the same tubing design supports different procedures, including infusion, sampling, perfusion, or temporary catheter connections.
Flexible construction allows the tubing to connect small experimental components without requiring a rigid fluid path, while smooth walls support controlled movement of liquids. These features are useful when fluid access must be established in a biological preparation. Careful handling remains important because reliable fluid delivery also depends on secure connections and appropriate sizing.
A practical workflow begins by choosing tubing with a suitable size for the intended fluid-access arrangement. The tubing is then connected securely to the selected syringe, needle, or pump and handled carefully during placement or use. Before relying on the setup for measurements, researchers should attend to connection security and potential leakage or flow variation.
Common uses include vascular cannulation, infusion, sampling, and perfusion. In these procedures, the tubing provides a route for controlled fluid access or transfer within a small animal model or isolated biological system. Its usefulness extends across experiments that require temporary catheter connections and dependable handling of liquids during biological measurements.
Careful selection and handling can help reduce leakage, unwanted flow variation, and tissue damage. Secure connections support more dependable fluid movement, while appropriate sizing helps the tubing fit the experimental arrangement. Together, these practices improve the consistency and reproducibility of measurements, which is important when comparing results across biological procedures or experimental preparations.
