Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

The video demonstrates the generation of tilted amygdala slices from a mouse brain. The brain is positioned at an angle on the vibratome specimen stage to obtain slices containing the amygdala and axons from the medial prefrontal cortex that form synaptic connections with the amygdala. The brain slices are maintained at the physiological temperature to preserve the tissue for further experiments.

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire A wing is the major lift-generating apparatus in an airplane. Wing performance can be further enhanced by deploying high-lift devices, such as flaps (at the trailing edge) and slats (at the leading edge) during takeoff or landing. In this experiment, a wind tunnel is utilized to generate certain airspeeds, and a Clark Y-14 wing with a flap and slat...

We describe a "gold standard" for evaluating orthostatic tolerance (OT) using tilt testing with combined lower body negative pressure (LBNP). This can be combined with non-invasive evaluations of cardiovascular reflex control. Normal and abnormal responses are defined.

This article describes a standard method to get a three-dimensional (3D) reconstruction of biological macromolecules using negative staining electron microscopy (EM). In this protocol, we explain how to get the 3D structure of the Saccharomyces cerevisiae exosome complex at medium resolution using the random conical tilt reconstruction method (RCT).
FAQs
The maneuver changes the position of structures that can narrow the upper airway in an unresponsive person. Gentle head extension combined with chin elevation moves the tongue and other soft tissues away from the posterior pharynx, creating a clearer passage for air. This mechanical effect explains why positioning is important before rescue breathing or ventilation.
Head Tilt Chin Lift requires neck movement, so it is not the preferred approach when cervical spine injury is suspected. In that situation, an alternative technique is used to limit neck movement while addressing the airway. This distinction balances the immediate need to support airflow with the need to avoid unnecessary motion of a potentially injured spine.
Correct positioning can determine whether air passes effectively through an otherwise obstructed upper airway. By helping move soft tissues away from the posterior pharynx, the maneuver may improve airflow and oxygen delivery. It also supports more effective rescue breathing or ventilation, making airway positioning an important part of early assessment and resuscitation.
Head Tilt Chin Lift is used for an unresponsive person when no cervical spine injury is suspected. It may be applied during first aid, cardiopulmonary resuscitation, and patient assessment. In these settings, the maneuver helps restore or maintain airflow and prepares the airway for subsequent rescue breathing or ventilation when required.
The essential sequence is to gently extend the head and elevate the chin, then use the resulting airway position to support airflow. The maneuver is performed before rescue breathing or ventilation when those interventions are needed. Its purpose is not forceful movement, but careful repositioning of the head and chin to help clear the upper airway.
During patient assessment, airway positioning helps determine whether an unresponsive person can receive adequate airflow. When the upper airway has been opened and cervical injury is not suspected, the maneuver can precede rescue breathing or ventilation. Its clinical value lies in supporting air passage and improving the conditions for subsequent resuscitation efforts.
