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.

Administering Oxygen by Nasal Cannula

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...

Melting Land and Sea Ice ExpandNOTE: This activity is a simulation of land- and sea-ice melting and their effects on water levels. First, label one graduated cylinder as 'Sea Ice' and the other graduated cylinder as 'Land Ice.' Hypotheses: the experimental hypothesis might be that the land ice melting will cause the water level to rise more than the melting sea ice. The null hypothesis would be that there will be no difference in the change in water level between the two containers. Add 10 ice...

The certainty of climate change remains a public controversy despite the consensus among approximately 97% of active climate researchers, who not only agree that the Earth’s climate is changing but also state that this change is intensified by human activity, predominantly carbon emissions 1. The disconnect between the public and the experts is partly due to poor understanding of the mechanisms involved in climate change as well as the differences among essential concepts such as weather and...

Total Factor Productivity (TFP) measures the efficiency with which inputs are transformed into outputs in production. It is the essence of economic growth, driven by technological advancement. Consider the agricultural sector, where production requires vast amounts of human labor and work animals. Today, modern farm machinery and agriculture technologies have revolutionized how we cultivate crops and produce food much more efficiently. TP = A*f(K, L) TFP is represented as a multiplier 'A' in...
FAQs
Mucus can narrow or block the removable inner cannula, making the airway less clear and potentially interfering with effective ventilation. Assessing the cannula for secretion buildup allows the clinician to recognize an obstruction-related problem during care. This is why secretion assessment remains central to maintaining airway patency and supporting patient safety.
Regular assessment helps identify secretion-related obstruction before it compromises airway function. A timely change or cleaning can restore a clearer passage through the tracheostomy tube, supporting effective ventilation and reducing avoidable airway risk. The appropriate interval depends on ongoing clinical assessment rather than treating the cannula as a component that can be ignored between routine care episodes.
The removable component provides a part of the tracheostomy tube that can be taken out for inspection, cleaning, or replacement. This allows clinicians to address mucus or blockage without describing the entire tracheostomy tube as a single nonserviceable unit. Its removable design therefore supports ongoing airway maintenance in clinical and community care.
The clinician should assess the removed cannula for mucus and blockage, because these findings show whether secretions are affecting the airway passage. That assessment connects the care decision to the patient’s immediate airway-maintenance needs. It also provides a practical check that the removable component is being managed to support clear airflow and effective ventilation.
The procedure begins with stabilizing the tracheostomy, followed by removing the inner cannula. The clinician then examines it for mucus or blockage and inserts a clean or replacement cannula. Appropriate infection-prevention practices apply throughout the process. These steps combine airway support, inspection, and re-establishment of the removable component in a controlled sequence.
Training is relevant wherever people manage tracheostomies, including hospitals, long-term care settings, and the community. Clinicians and caregivers need to understand stabilization, removal, inspection, and reinsertion, as well as infection-prevention practices. Consistent training supports safer care, helps maintain a clear airway, and promotes timely attention to secretion-related obstruction.
