In this Emerging Technology Review, a novel, wireless, wearable Doppler ultrasound patch is described as tool for resuscitation. The device designed, foremost, functional hemodynamic monitor—a simple, fast, and consistent method measuring change with preload variation. More generally, monitoring paradigm that helps predict stroke volume response to additional intravenous volume. Because of the ...

Monitoring tool degradation during manufacturing can ensure product accuracy and reliability. However, due to variations in conditions complexity signal analysis, effective broadly applicable monitoring is still challenging achieve. Herein, a novel method using ultrasound signals augmented with numerically trained machine learning technique reported monitor the wear condition of friction stir w...

Abstract The setting behavior of concrete mixtures can be indirectly monitored by the penetration resistance test given ASTM C 403. Arbitrary values are associated to initial and final set times. This is carried out on previously sieved mortar portion mixture, which makes its practical use rare. Alternatively, ultrasound testing used characterize this transition period, since propagation ultras...

We report two methods of intraoperative fetal heart rate (FHR) monitoring in cases of cerebral arteriovenous malformation surgery during pregnancy. In one case in her third trimester, cardiotocography was used. In another case in her second trimester, ultrasound sonography was used, with a transesophageal echo probe attached to her lower abdomen. Especially, the transesophageal echo probe was u...

Variations in fetal heart rate (FHR) is a potential indicator of stress on unborn in the womb of mother. In hospitals, FHR surveillance is performed by ultrasound based Doppler equipments. However, recent studies show that frequent exposure to ultrasound radiations is not recommended for the fetal well-being. Because of this and many other reasons, these instruments are not recommended for prol...
