conclusions this study suggests that obese patients in hs may have a higher risk of hemodynamic instability compared to their nonobese counterparts primarily due to obesity-induced increases in intra-abdominal pressure resulting in reduced venous return. results in hemorrhage simulation, moderate increases in bmi were found to produce greater decreases in map and co compared to the normal subje...

Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...

results we performed rush on 77 patients. kappa index was 0.71 (p value = 0.000), reflecting acceptable general agreement between initial impression and final diagnosis. for hypovolemic, cardiogenic and obstructive shock, the protocol had an npv above 97% yet it had a lower ppv. for shock with distributive or mixed etiology, rush showed a ppv of 100% but it had low sensitivity. subgroup analysi...

conclusions hepatic shock is detected in ill patients, especially those with hemodynamic disorders. it can be prevented by early treatment of underlying disease. there is no definite treatment for hepatic shock and should be managed conservatively. hepatic shock in patients can increase the mortality rate. results different causes can lead to hepatic shock. most of these causes can be prevented...

in this paper, the effects of scintillation phenomena on bit error rate (ber) and signal to noise ratio (snr), which are essential characteristics in free space optical (fso) communication system, are studied. until now various methods have been introduced to decrease ber and increase the link's reliability. optimizing snr is one of the fundamental methods to decrease ber value. intensity fluct...
