Multifunctional Adhesive Hydrogel for Rapid Cardiac Hemostasis and Antibacterial Protection

Advanced Materials Technologies, EarlyView.
A multifunctional polyacrylamide/gelatin/tannic acid hydrogel (PGT) is presented for rapid cardiac hemostasis under wet, dynamic conditions. Surface tannic acid coating enables instantaneous wet adhesion, accelerates coagulation, and confers antibacterial activity within a single platform.

How effective are chest compressions when wearing mask? A randomised simulation study among first-year health care students during the COVID-19 pandemic

BMC Emergency Medicine, 2022
Background The resuscitation guidelines provided for the COVID-19 pandemic strongly recommended wearing personal protective equipment. The current study aimed to evaluate and compare the effectiveness of chest compressions and the level of fatigue while ...

SERS Facemask for Rapid and Portable Sensing Mycobacterium Tuberculosis Antigens for TB Screening

Advanced Science, EarlyView.
Our study introduced an Au─Ag embedded covalent organic framework (U@COF) ‐mediated facemask for sensing TB antigen ESAT‐6/CFP‐10 complex in clinical droplet samples toward TB screening. Practical analysis of clinical samples demonstrated the availability of our facemask, which is capable of identifying the TB subjects (N = 17) from healthy candidates (

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Mechanical versus manual chest compressions in the treatment of in-hospital cardiac arrest patients in a non-shockable rhythm: a randomised controlled feasibility trial (COMPRESS-RCT)

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2018
Background Mechanical chest compression devices consistently deliver high-quality chest compressions. Small very low-quality studies suggest mechanical devices may be effective as an alternative to manual chest compressions in the treatment of adult in ...

Closed chest compressions reduce survival in an animal model of haemorrhage-induced traumatic cardiac arrest.

Resuscitation, 2017
Closed chest compressions (CCC) are recommended for medical cardiac arrest, but there is little evidence to support their inclusion for traumatic cardiac arrest (TCA).
