It has been suggested to acquire circulatory information from patients undergoing resuscitation from cardiac arrest by analyzing their thoracic electrical impedance using modified automated external defibrillators (AEDs). To investigate the potential of this idea, we studied the correlation between two impedance-derived parameters related to circulation,(More)
Possible clinical states of a cardiac arrest patient are ventricular fibrillation/tachycardia (VF/VT), asystole (ASY) or pulseless electrical activity (PEA), and the treatment goals are return of spontaneous circulation (ROSC) and neurologically intact survival. Waveform analysis has been used in VF to predict treatment outcomes and we hypothesised that(More)
BACKGROUND In 1993, Ullevaal University Hospital started CT pelvimetry. The accuracy of CT pelvimetric measurements and a low fetal dose are very important. In our study we tested the accuracy of CT pelvimetry and measured the fetal dose and the effective dose to the mother. METHOD A lead scalar was exposed in different heights compared to the isocentre.(More)
Several studies have shown that the carotid pulse check is time-consuming and inaccurate. The sensitivity and specificity of manual pulse check has been reported to be 90% and 55% respectively. It has been suggested that circulatory information can be acquired by measuring the thoracic impedance via the defibrillator pads. We established a dataset of(More)
