INTRODUCTION Lung-protective ventilation aims at using low tidal volumes (VT) at optimum positive end-expiratory pressures (PEEP). Optimum PEEP should recruit atelectatic lung regions and avoid tidal recruitment and end-inspiratory overinflation. We examined the effect of VT and PEEP on ventilation distribution, regional respiratory system compliance(More)
A novel neural chip SAND (Simple Applicable Neural Device) is described. It is highly usable for massive parallel neural network computations. The chip is optimized for a high input data rate (50 MHz, 16 bit data) at a very low cost basis. The performance of a single SAND chip is 200 MOPS due to four parallel 16 bit multipliers and 40 bit adders working in(More)
INTRODUCTION Assessment of respiratory system compliance (Crs) can be used for individual optimization of positive end-expiratory pressure (PEEP). However, in patients with spontaneous breathing activity, the conventional methods for Crs measurement are inaccurate because of the variable muscular pressure of the patient. We hypothesized that a PEEP wave(More)
INTRODUCTION Patients with acute respiratory distress syndrome (ARDS) typically show a high degree of ventilation inhomogeneity, which is associated with morbidity and unfavorable outcomes. Electrical impedance tomography (EIT) is able to detect ventilation inhomogeneity, but it is unclear which method for defining the region of interest (ROI) should be(More)
BACKGROUND Implantation of left atrial appendage (LAA) occlusion devices was shown to be a feasible and effective alternative to oral anticoagulation in patients with non-valvular atrial fibrillation. However, only few data about in-hospital and peri-procedural data are currently available. This study aims to report about echocardiographic, procedural and(More)
In the previous issue of Critical Care, we read with interest the article by Blankman and colleagues [1], who studied the performance of various electrical impedance tomog-raphy (EIT)-derived measures in detecting the 'best' positive end-expiratory pressure. The aim of that study is relevant; however, the article contains some methodo-logical inaccuracies(More)
The case presents a wall adherent structure in the right atrium in a young patient with peripheral t-cell lymphoma followed by successful prolonged lysis therapy resulting in the resolution of the thrombus is presented. This case highlights the utility of multimodality imaging in an accurate assessment of the right atrium thrombus and the effectiveness of(More)
BACKGROUND Several acute complications related to takotsubo cardiomyopathy (TTC) have been documented recently. However, the incidence and clinical significance of acute thromboembolic events in TTC is not well established. METHODS A detailed investigation of the clinical characteristics and in-hospital complications of 114 consecutive patients diagnosed(More)
the previous issue of Critical Care, we read with interest the article by Al-Rawas and colleagues [1], who proposed a method for the determination of respiratory system mechanics (RSM) in diff erent ventilatory modes. We have some concerns regarding the applicability of the described method during pressure support ventilation (PSV). In particular, all(More)
