Experimental aspiration of water soluble contrast agents was performed on rats via transoral endotracheal injection. Iopamidol, iohexol and diatrizoate were the contrast agents tested. One group of rats received normal saline as a control. Adjusted lung weights were measured at 2 and 24 hours post aspiration. Radiographs were taken at 2 and 24 hours post(More)
BACKGROUND Previous investigations of out-of-hospital cardiac arrest (OHCA) have shown that the waveform characteristic amplitude spectral area (AMSA) can predict successful defibrillation and return of spontaneous circulation (ROSC) but has not been studied previously for survival. OBJECTIVES To determine whether AMSA computed from the ventricular(More)
BACKGROUND AND PURPOSE Immune therapy against amyloid-β appears to be a promising target in Alzheimer disease. However, a dose-related risk for ARIA on FLAIR images thought to represent parenchymal vasogenic edema or sulcal effusion (termed "ARIA-E"), has been observed in clinical trials. To assess the intensity of ARIA-E presentation, an MR imaging scale(More)
OBJECTIVE In out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF) the frequency-based waveform characteristic, amplitude-spectral area (AMSA) is associated with hospital discharge and good neurological outcome, yet AMSA is also known to increase in response to chest compressions (CC). In addition to rate and depth, well performed CC(More)
BACKGROUND In retrospective swine and human investigations of ventricular fibrillation (VF) cardiac arrest, the amplitude-spectral area (AMSA), determined from the VF waveform, can predict defibrillation and a return of spontaneous circulation (ROSC). OBJECTIVES We hypothesized that an algorithm using AMSA in real time to direct postshock chest(More)
