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...

The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas. Nasal Cannula A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen. Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min. Oxygen percentage setting:...

Size and site must match the biological location and intended task. A suitable choice supports the required fluid delivery, withdrawal, sampling, or monitoring while reducing unnecessary tissue disruption. An unsuitable combination can make positioning difficult or limit access. In experimental biology, this selection step links the physical design of the cannula to the quality and reliability of the planned measurement or intervention.
Controlled advancement helps the operator position the hollow tube while minimizing trauma to surrounding tissue. Careful positioning also preserves a usable access route, which is important when the cannula must support delivery, withdrawal, sampling, or monitoring. In this context, the insertion motion affects more than placement: it can influence whether the device remains functional and whether subsequent biological measurements or interventions can proceed reliably.
Repeated access depends on more than initial placement. The cannula must remain secured and the route must stay usable without blockage or leakage. Ongoing observation is also important because infection or tissue damage can compromise the model and the intended experiment. These considerations make stability and condition monitoring central when researchers need access at more than one time point.
A careful sequence begins with a sterile cannula, followed by selection of an appropriate size and site. The device is then positioned and advanced in a controlled manner, secured to maintain a stable route, and monitored afterward. This workflow connects preparation, placement, and follow-up rather than treating insertion as a single isolated movement.
Monitoring should focus on blockage, leakage, infection, and tissue damage. A blockage can interfere with planned delivery, withdrawal, or sampling, while leakage can undermine controlled access. Infection or damage may affect the biological model and the reliability of observations. Detecting these problems is therefore part of maintaining the cannula's function and the quality of the experiment.
Applications include drug administration, blood sampling, perfusion, pressure measurement, and repeated access in living models. The same access route can support either an intervention or collection of biological information, depending on how it is positioned and managed. This versatility makes cannulas useful when experiments require controlled access to vessels, cavities, tissues, or organs over a planned observation period.
