The role of the left ventricle in ICU patients with circulatory shock has long been considered. However, acute right ventricle (RV) dysfunction causes and aggravates many common critical diseases (acute respiratory distress syndrome, pulmonary embolism, acute myocardial infarction, and postoperative cardiac surgery). Several supportive therapies, including mechanical ventilation and fluid manag...

This case report details the development of cardiogenic shock after craniotomy in a patient sedated with a propofol infusion. The patient survived with the assistance of extracorporeal membrane oxygenation. A literature review summarizes the syndrome of cardiogenic shock associated with prolonged propofol infusion. This is the first report of survival in this syndrome resuiting from mechanical ...

P harmacologic management of patients with cardiac arrest or cardiogenic shock may be insuI cient in restoring adequate circulatory support. This has led physicians to investigate and develop more aggressive interventions for these problems. Cardiogenic shock most frequently occurs in the following clinical settings: (1) acute myocardial infarction; (2) postcardiotomy; (3) an acute exacerbation...

BACKGROUND There are contradictory reports concerning hypercapnia as a predictor of a better outcome in COPD. This study examined the clinical implications of hypercapnea in COPD patients (M:F = 59:19) who required mechanical ventilation. METHODS The clinical parameters at the time of MICU admission, the total ventilation time, the APACHE II score and the pulmonary function testing were retro...

We describe the case of fulminant myocarditis due to Lyme disease and use of mechanical circulatory support (MCS) for the treatment of the Lyme carditis associated with refractory cardiogenic shock. Fulminant Lyme myocarditis in young adult male patient led to a sudden onset of acute, severe biventricular heart failure with progressive cardiogenic shock, and multiorgan failure immediately after...

In heterogeneous media, the scattering due to interfaces between dissimilar materials play an important role in shock wave dissipation and dispersion. In this work the influence of interface scattering effect on shock waves was studied by impacting flyer plates onto periodically layered polycarbonate/6061 aluminum, polycarbonate/304 stainless steel and polycarbonate/glass composites. The experi...

Conventional knee supporters generally reduce pain by restricting joint movement. In other words, there were no mechanical that functioned powerfully. Considering this problem, we first devised a device in which spring is inserted into the double structure of cylinder and piston, braking action applied to piston. This mechanism retracts when angle exceeds certain level. Next, modeled, dynamic c...

We present an investigation into the effect of the motion of a printed circuit board (PCB) on the response of a microelectromechanical system (MEMS) device to shock loads. A two-degrees-of-freedom model is used to model the motion of the PCB and the microstructure, which can be a beam or a plate. The mechanical shock is represented as a single point force impacting the PCB. The effects of the f...
