Cardiac-related failure of weaning from mechanical ventilation is an important reason for prolonged mechanical ventilation, intensive care unit treatment, and increased morbidity and mortality. When transthoracic echocardiography (TTE) is routinely performed before a weaning trial, patients at high risk of cardiac-related failure can be detected by low left ventricular (LV) ejection fraction, d...

STUDY OBJECTIVE To report the outcome of patients with autologous peripheral blood stem cell transplantation (PBSCT) receiving mechanical ventilation. DESIGN Retrospective observational study. SETTING Active hematopoietic stem cell transplantation center and a university hospital medical ICU. PATIENTS Patients with autologous PBSCT receiving mechanical ventilation. METHOD A review of th...

OBJECTIVES Between 10% and 20% of children submitted to mechanical ventilation in the pediatric intensive care unit present extubation failure. Several ventilatory indexes have been proposed to predict extubation failure. The aim of this study was to analyze the accuracy of these indices in predicting successful extubation in children and to evaluate these variables according to the age of the ...

BACKGROUND Excision of a bone tumor requires reconstruction if limb salvage is a priority. Reconstruction with an endoprosthetic implant is preferred in our unit, as the patient typically can return rapidly to full weight-bearing and functional activities. Long-term complications, such as deep infection, aseptic loosening, and mechanical failure of the implants, have led to concerns about the e...

Mechanical ventilation is a therapeutic intervention involving the temporary replacement of ventilatory function with the purpose of improving symptoms in patients with acute respiratory failure. Technological advances have facilitated the development of sophisticated ventilators for viewing and recording the respiratory waveforms, which are a valuable source of information for the clinician. T...

This paper presents the results of investigation carried out to improve the mechanical toughness of cement mortar. Toughness is a basic parameter which has to be improved in brick walls, concrete roads, machine foundations, dams etc. Materials fails due to an impact force and vibrations resulting in minor cracks and bonding failure between bricks, it leads to failure of the structure. In order ...

Block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. In such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. In this paper, first, a brief review of previous studies on toppling failures is presented. Then, the physical and mechanical properties of experimental mode...

Patients with prolonged mechanical ventilation have a high one year mortality, with recognized contributing factors including COPD, cardiac failure, renal failure, and respiratory muscle weakness.1 The study by Diaz-Abad et al2 shows that obstructive sleep apnea (OSA) is very common among selected obese patients who have weaned from prolonged mechanical ventilation. The study raises as many que...
