2023
Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the...

COVID-19 / Coronavirus Outbreak: Protecting The Airway - Endotracheal Intubation
0 Views •
2020
In pandemic times, medical staff is becoming a key resource in fighting the infection. To achieve the best medical care, relevant techniques and procedures have to be taught to medical staff to reduce the risk of infection. COVID patients often need mechanical ventilation due to progredient respiratory insufficiency, so an endotracheal intubation becomes a critical procedure in managing these patients. This procedure has an increased risk of infection due to aerosol formation and working with...

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

We describe a strategy to monitor maturation and migration of pulmonary dendritic cells in response to ovalbumin in the setting of ovalbumin induced allergic airway inflammation. This strategy can be modified to assess migration of pulmonary dendritic cells in settings of infection.

A Reversible, Non-invasive Method for Airway Resistance Measurements and Bronchoalveolar Lavage Fluid Sampling in Mice

Repeated measurements of rodent respiratory physiology and sampling of airway inflammatory cells are desirable, but generally not feasible. Here we describe a repeatable method for orally intubating mice that permits repeated measurements of airway hyperreactivity and sampling of airway inflammatory cells.
FAQs
The hollow lumen provides a controlled passage through which air, oxygen, fluids, or instruments can move. This makes the catheter adaptable to several airway tasks rather than limiting it to a single function. Depending on the clinical need, the same access pathway can support ventilation management, secretion removal, or selected interventions performed during airway procedures.
Suction uses the catheter’s lumen to remove mucus and other material that may obstruct airflow. Clearing these secretions helps preserve airway patency, meaning the passage remains open, and supports oxygenation. Its value is greatest when accumulated material interferes with effective airflow, although the process must be performed carefully to avoid airway trauma, hypoxia, or other complications.
An airway catheter must be positioned with the respiratory tract’s anatomy in mind because incorrect placement can prevent the intended access or intervention from working properly. It may also contribute to trauma, inadequate oxygenation, or other safety problems. Attention to anatomical landmarks and placement technique therefore directly influences whether the catheter maintains useful airway access without introducing avoidable harm.
Sterility helps reduce the risk of introducing infection into the respiratory tract during placement or use. This consideration applies alongside anatomical accuracy and patient monitoring because a technically effective catheter can still create harm if contamination occurs. Maintaining appropriate sterile practice supports safer secretion clearance, airway access during procedures, and selected emergency or critical-care interventions.
Clinicians should consider airway anatomy, the intended purpose of the catheter, sterility, and the patient’s immediate safety. They must also remain alert to trauma, infection, hypoxia, obstruction, and incorrect placement. These factors guide how the catheter is introduced and used, helping preserve airway patency and oxygenation while matching the intervention to the patient’s clinical need.
Clinical teams may use airway catheters to clear secretions, maintain access to the airway during procedures, or support selected emergency and critical-care interventions. The appropriate use depends on the required airway access and whether the goal is ventilation management, removal of obstructing material, or passage of oxygen, fluids, or instruments. Outcomes depend on careful placement and safe handling.
