Ultrasensitive, light-induced reversible multidimensional biosensing using THz metasurfaces hybridized with patterned graphene and perovskite

Nanophotonics, 2022
Biosensors based on terahertz (THz) metasurfaces have recently attracted widespread attention. However, few have been reported so far because it is a challenge to achieve ultrasensitive multidimensional detection in the THz spectrum.

Assessment of Pendelluft Using Electrical Impedance Tomography in a Patient With Flail Chest. [PDF]

Respirol Case Rep
This case illustrates that EIT‐guided management of flail chest should focus on stabilising the visible chest wall and achieving homogenised ventilation dynamics. ABSTRACT An 80‐year‐old man with flail chest exhibiting paradoxical chest wall movement required mechanical ventilation for internal fixation.

Regional ventilation in spontaneously breathing COVID‐19 patients during postural maneuvers assessed by electrical impedance tomography

Acta Anaesthesiologica Scandinavica, Volume 67, Issue 2, Page 185-194, February 2023., 2023
Abstract Background Gravity‐dependent positioning therapy is an established concept in the treatment of severe acute respiratory distress syndrome and improves oxygenation in spontaneously breathing patients with hypoxemic acute respiratory failure. In patients with coronavirus disease 2019, this therapy seems to be less effective. Electrical impedance
