Source: Nicholas Timmons, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA The goal of this experiment is to test the concept of the conservation of momentum. By setting up a surface with very little friction, collisions between moving objects can be studied, including their initial and final momenta. The conservation of momentum is one of the most important laws in physics. When something is conserved in physics, the...

Source: Xavier, A. L. R., et al. Cannula Implantation into the Cisterna Magna of Rodents. J. Vis. Exp. (2018)This video demonstrates the procedure for implanting a cannula into the cisterna magna of an anesthetized mouse. The technique involves guiding a needle-mounted cannula through the dura into the inverted triangular cisterna magna and securing it for targeted delivery into the cerebrospinal fluid.

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function. Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...

Administering Oxygen by Nasal Cannula

2025
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations. Nasal Cannulas A nasal cannula is a lightweight tube split into two prongs placed in the nostrils, connected...

Conservation of Energy Approach to System Analysis

Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI The purpose of this experiment is to demonstrate the application of the energy conservation equation to determine the performance of a flow system. To this end, the energy equation for steady, incompressible flow is applied to a short pipe with a gate valve. The gate valve is then gradually closed and its influence on flow conditions is characterized. In...

The reservoir fills with oxygen during exhalation, then releases that stored gas as a concentrated bolus at the beginning of the next inhalation. This timing targets delivery to the phase when oxygen can reach the lungs, helping the supply support oxygen administration more efficiently than releasing the stored gas during exhalation.
Some systems detect or coordinate with the patient’s inspiratory effort, making delivery dependent on the start of inhalation rather than an uninterrupted flow. That interaction makes breathing pattern clinically important because irregular or changing inspiratory effort may affect synchronization. Selection and adjustment should therefore account for how the individual breathes.
Performance depends on more than the cannula itself. Oxygen saturation, breathing pattern, activity level, and prescribed flow requirements help determine whether a conserving system is appropriate and how it should be adjusted. These variables matter because a setting that suits one patient or situation may not provide the same practical support during another level of activity.
Clinical selection begins with assessment of the patient’s breathing pattern, oxygen saturation, activity level, and prescribed flow requirements. This process links device behavior to the patient’s actual needs and helps determine whether the conserving approach remains suitable as activity demands or oxygen requirements change. Adjustment should follow the same clinical factors rather than rely on device use alone.
For portable supplies, conserving delivery can extend cylinder duration, allowing patients to use available oxygen more efficiently during ambulatory therapy. This supports mobility by making oxygen administration more practical outside a fixed location. The approach also remains relevant to stationary supplies, where improved efficiency can simplify longer-term oxygen administration for people with chronic respiratory conditions.
Oxygen saturation is one of the clinical measures used when selecting or adjusting the device. Considered alongside breathing pattern, activity level, and prescribed flow requirements, it helps clinicians relate the conserving system to the patient’s oxygen needs. This assessment is particularly relevant when supporting long-term oxygen administration or ambulatory therapy in chronic respiratory conditions.
