Introduction: Aspiration of foreign body can cause partial obstruction, secondary inflammation or complete obstruction of tracheobronchial tree and sometimes may lead to death. This study was aimed to investigate the main causes of foreign body aspiration in patients referred to Bandar Abbas medical centers. Methods: In this cross-sectional and analytic study, 134 patients with foreign body a...
This paper analyses the dynamic behavior of a rail vehicle using experimental and simulation analysis on multi-rigid–flex body model. The mathematical models are developed considering car body, bogie frame, wheel axle for vehicles rigid–flexible multi-rigid formulations, taking as rigid flexible flex–rigid analysis. A finite element model was in ANSYS, substructure modal were performed. is vali...
A misaligned rigid rotor system with flexible supports differing from the traditional system, which refers to its practical rotating center line determined by offset theoretical one, often suffers support structure damage risk. In present work, dynamic characteristics of a squirrel cage are focused, and vibrations stress structures under different offsets investigated experimental simulated ana...
Background Although both methods of spontaneous respiration and controlled ventilation during anesthesia are safe and effective for managing children with foreign body aspiration, there is no consensus from the literature as to which technique is optimal. This study aimed to determine the outcomes of anesthetic techniques in pediatric rigid bronchoscopy for foreign body removal. Materials and M...
