Use of personal protective equipment and cognitive load during cardiopulmonary resuscitation – A randomized cross-over simulation-based study

Resuscitation Plus
Background: The use of personal protective equipment (PPE) is essential during cardiopulmonary resuscitation (CPR) to prevent disease transmission, but its impact on rescuer fatigue and CPR quality remains debated.

Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery

Advanced Optical Materials, EarlyView.
Optically trapped whispering‑gallery microlasers are precisely positioned onto non‐phagocytic mammalian cells to report local refractive‑index changes in real time. Time‑dependent wavelength shifts reveal successive stages from membrane contact to internalization.

Effect of increased static lung recoil on bronchial dimesions of excised lungs [PDF]

, 1975
We measured bronchial diameters and lengths during static deflation and inflation in eight excised dog lobes before and after static lung recoil (Pst(L)) had been significantly increased by cooling the lobe for 48 h at 4 degrees C and ventilating it for

A novel approach to recoil pad enhancement in rifles via topological design with material extrusion and SLA

Frontiers in Mechanical Engineering
Excessive recoil in firearms reduces shooting accuracy, causes user discomfort, and increases mechanical wear over time. This creates a need for effective solutions that can improve recoil management.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Feedback devices may not improve chest compression depth during simulated out-of-hospital cardiac arrest: a multicenter randomized controlled trial

Emergency Care Journal
Out-of-hospital cardiac arrest (OHCA) survival remains low, with high-quality cardiopulmonary resuscitation (CPR) essential to improving outcomes. The i-gel® device allows continuous compressions but has been associated with reduced compression depth ...
