Source: Shreyas Narsipur, Mechanical and Aerospace Engineering, North Carolina State University, Raleigh, NC Fluid pressure is an important flow characteristic that is required to determine the aerodynamics of a system. One of the oldest and still existing pressure measurement systems is the manometer due to its accuracy and simplicity of operation. The manometer is generally a U-shaped glass tube that is partially filled with liquid, as shown in Figure 1. The U-tube manometer requires no...

In pressure myography, an intact small segment of a vessel is mounted onto two small cannulas and pressurized to a suitable luminal pressure. Here, we describe the method to measure vasorelaxation response of the mouse 3rd order mesenteric arteries in c57 and sGCα1-/- mice using pressure myography.

We present a preparation for visualizing and manipulating calcium signaling in native, intact microvascular endothelium. Endothelial tubes freshly isolated from mouse resistance arteries supplying skeletal muscle retain in vivo morphology and dynamic signaling within and between neighboring cells. Endothelial tubes can be prepared from microvessels of other tissues and organs.

Pressure myography is used to assess vasoactivity of small arteries that develop sustained constriction when pressurized. This manuscript provides a detailed protocol to assess in isolated segments of small mesenteric arteries from rats, vasoactivity and the effect of intraluminal pressure on vascular diameter.

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...
FAQs
Material strength, wall thickness, and flexibility jointly determine how tubing responds to pressure. Stronger material and an appropriate wall dimension help the tube carry applied loads, while flexibility affects how readily it deforms. Selection must also account for whether pressure acts inside or outside the tube, because the relevant failure concern may be expansion, collapse, leakage, or rupture.
The tube’s wall distributes pressure around the conduit rather than allowing the applied force to act at a single point. This distribution helps limit expansion when internal pressure is elevated and collapse when external pressure dominates. Maintaining the intended wall response supports containment and reduces the likelihood that deformation will lead to leakage or rupture.
Internal and external pressure create different demands on a tube. Internal pressure can drive outward expansion, whereas external pressure can promote inward collapse. Environmental equipment may encounter either condition during groundwater sampling, deep-water work, or subsurface monitoring. Accounting for both pressures helps maintain measurement stability and protects the integrity of fluid-handling pathways.
Selection begins with the pressure conditions the system is expected to encounter, including whether the dominant load is internal or external. Researchers then consider material strength, wall thickness, flexibility, and resistance to deformation. Matching these characteristics to the intended setting helps prevent leakage or rupture while supporting reliable operation in field or laboratory conditions.
Environmental researchers use this tubing in groundwater sampling, deep-water instruments, and subsurface instruments, where pressure can challenge fluid pathways and measurement components. It also supports controlled transfer of pressurized gases or liquids. These applications benefit from tubing that maintains integrity under demanding conditions, helping preserve the stability and reliability of measurements or transfers.
Appropriate tubing selection improves measurement stability by helping the conduit retain its intended shape and containment under specified pressure conditions. It also supports system safety by reducing risks associated with leakage or rupture, while improving durability during field and laboratory work. Consequently, tubing performance can influence both the dependability of collected environmental data and the service life of the setup.
