This protocol is designed to describe a method to place and establish a supraglottic (alternative) airway during neonatal resuscitation. It can be used in situations where frontline providers cannot ventilate or endotracheally intubate neonates requiring resuscitation.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual masking is a term used by perceptual scientists to refer to a wide range of phenomena in which in an image is presented but not perceived by an observer because of the presentation of a second image. There are several different kinds of masking, many of them relatively intuitive and unsurprising. But one surprising and important type of masking is called Object Substitution Masking. It has been a focus of research in vision...

Here we explore contralateral tactile masking between the forearms in which tactile detection thresholds are modulated by vibration applied to a remote site. The details of which remote sites have an effect can tell us about how the body is represented in the brain.

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...

Preoxygenation Techniques for Tracheal Intubation in Critically Ill Adults Utilizing Oxygen Mask and Noninvasive Ventilation

2025
We present evidence-based preoxygenation strategies that demonstrate the use of oxygen masks and noninvasive positive pressure ventilation to optimize oxygenation in critically ill patients undergoing emergent tracheal intubation, thereby reducing the risk of hypoxemia, extending safe apnea time, and minimizing complications.
FAQs
Filtration, interception, and fit contribute different parts of the barrier effect, so evaluating only one can give an incomplete picture. Material properties influence how particles are handled, while the facial seal affects whether air moves through the intended barrier. Considering these features together helps explain why performance may vary across masks or wearing conditions.
Airborne particle size and concentration should be treated as core study variables because they influence how effective a mask may be under a given exposure. A design that changes these conditions can alter the apparent reduction in particles entering or leaving the airway. Reporting them helps researchers interpret transmission and respiratory-risk findings accurately.
Duration of use matters because effectiveness is not a fixed property independent of conditions. Studies should consider how long a mask is worn alongside its facial seal and material properties. This makes it possible to distinguish an outcome associated with the barrier itself from one associated with changing wear conditions, especially when assessing respiratory exposure over time.
Researchers can examine whether changing masking conditions is associated with altered movement of infectious respiratory particles and corresponding transmission patterns. In immunology and infection studies, this approach connects an exposure-control measure with pathogen spread rather than treating transmission as an isolated outcome. It can help frame experiments on how respiratory exposure contributes to infection risk.
By incorporating airway masking into exposure studies, researchers can investigate whether differences in respiratory particle exposure coincide with changes in mucosal immune activation. This links physical exposure control to an immunological outcome at the respiratory surface. Such studies can help clarify how exposure conditions relate to host responses during infection research.
It is relevant when the research question concerns infection control, respiratory health, or the relationship between airborne exposure and disease risk. Its value extends beyond counting particles: investigators can consider material properties, facial seal, wear duration, particle size, and concentration when interpreting outcomes. These variables provide context for comparing respiratory exposure conditions in infection studies.
