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.

Intratracheal instillations deliver solutes directly into the lungs. This procedure targets the delivery of the instillate into the distal regions of the lung, and is therefore often incorporated in studies aimed at studying alveoli. We provide a detailed survival protocol for performing intratracheal instillations in mice.

Transgenic mice have been extremely useful in ascribing physiological function to genes. As such, research in general, and functional studies of airway, in particular, have undergone a remarkable shift toward murine models. Here we provide protocols for in vitro trachea constriction studies to evaluate smooth muscle function in murine airway.

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...
FAQs
An inflatable cuff can create a seal around the cannula when it is present, helping reduce air leakage from the airway. This sealing function supports more controlled delivery of air, anesthetic gases, or ventilatory assistance and helps researchers maintain consistent respiratory conditions. Because cuff use is not universal, its presence and condition become important variables when interpreting an experiment.
Bypassing the nose and mouth gives investigators direct access to the trachea, allowing respiratory support or gas delivery without relying on the upper airway route. This arrangement is useful when the experimental design requires controlled breathing conditions. It also distinguishes a tracheal cannula from approaches that leave airflow traveling through the normal nasal or oral passage.
A patent lumen must remain open for air, gases, or ventilatory support to reach the lungs. Monitoring therefore helps identify problems that could compromise access, including obstruction or tissue injury associated with placement. In respiratory physiology experiments, maintaining this access is necessary for interpreting changes in breathing and lung function rather than effects caused by a blocked or poorly positioned cannula.
Researchers should control and document the intended respiratory conditions, including whether the cannula is being used for air delivery, anesthetic gases, ventilatory support, or secretion sampling. They should also verify proper placement and monitor the airway during the study. These checks help preserve access to the respiratory system and reduce confounding from injury, leakage, or obstruction.
These cannulas provide a controlled route for examining breathing and lung function in experimental models. Researchers can regulate the conditions under which air or support reaches the lungs, then assess respiratory responses under defined circumstances. The approach is especially relevant when direct airway access is needed to connect controlled respiratory conditions with measured lung outcomes.
During anesthesia, the lumen can deliver anesthetic gases to the lungs; during mechanical ventilation, it can provide the airway route for ventilatory support. In both settings, reliable placement and an unobstructed passage are essential. If an inflatable cuff is used, its seal can help limit leakage and support more controlled delivery during the experiment.
Direct tracheal access allows researchers to collect airway secretions as part of an experimental assessment. This application differs from simply maintaining airflow because the cannula also serves as a route for obtaining respiratory material. Sampling can therefore complement measurements of lung function or breathing conditions in biology studies, provided placement and airway patency remain properly monitored.
