Operational failures in centrifuge pumps could be hydraulic or mechanical. However, most of these mechanical and hydraulic failures are connected cause of their operational nature and finding the right cause is due to considering numerous mechanical and hydraulic signs and parameters in pumps. On the other hand, due to non-linear and fluctuant behavior of pumps in the matter of time and not pre...

Clinical, epidemiological, and biomechanical studies suggest the involvement of the cervical facet joint in neck pain. Mechanical studies have suggested the facet capsular ligament to be at risk for subfailure tensile injury during whiplash kinematics of the neck. Ligament mechanical properties can be altered by subfailure injury and such loading can induce cellular damage. However, at present,...

long-term mechanical circulatory support is a life-saving technology while briding to heart transplantation. it increases the quality of life and preserves end-organ function for patients with  advanced heart failure. the number of patients with advanced heart failure scheduled for heart transplantation before comorbidities escalate is on the rise. however, the device function is complicated by...

INTRODUCTION It has been suggested that delayed intensive care unit (ICU) transfer is associated with increased mortality for patients with community-acquired pneumonia (CAP). However, ICU admission policies and patient epidemiology vary widely across the world depending on local hospital practices and organizational constraints. We hypothesized that the time from the onset of CAP symptoms to i...

OBJECTIVES To analyze the mechanical failures and malfunctions of the da Vinci Surgical (S) System during various robotic surgeries in 6 different departments at our institute and also evaluated the solutions for the failures and malfunctions. METHODS From July 2005 to December 2008, a total of 1797 robotic surgeries were performed at our institute. The surgeries were performed using 4 da Vin...

OBJECTIVE To review a large population of children receiving mechanical ventilation to establish a baseline rate of extubation success and failure and to identify those characteristics that place a patient at greater risk of failing planned extubation. DESIGN Retrospective chart review. SETTING University-affiliated children's hospital with a 20-bed pediatric ICU. PATIENTS All 632 patient...

Background: Preterm neonates are at a high risk of respiratory depression at birth. Incidence of respiratory distress is reported in 60-80% of the neonates born with the gestational age of less than 28 weeks and 15-30% of the neonates with the gestational age of less than 32-34 weeks. The present study aimed to compare the incidence and risk of failed extubation in using caffeine and aminophyll...
