Problem statement: Rotating turbine ventilators were generally found in most countries. They were simple in structure, light in weight and cheap to install. It was quite surprising that, the aerodynamics of this common device had not been numerically examined and the design process of most of these ventilators had developed progressively through trial and error methods. Approach: This study was...

Patients with congenital central hypoventilation syndrome (CCHS) develop alveolar hypoventilation resulting from a failure of central ventilatory control. Late-onset CCHS (LO-CCHS), which may be precipitated by severe respiratory infection or exposure to sedatives or general anesthesia, presents after the neonatal period. Since CCHS patients require lifelong mechanical-assisted ventilation, in ...

BACKGROUND The Fontan procedure is a successful palliation for children with single-ventricle physiology; however, many will eventually require heart transplantation. The purpose of this study was to determine risk factors for death awaiting transplantation and to examine results after transplantation in Fontan patients. METHODS AND RESULTS A retrospective, multi-institutional review was perf...

OBJECTIVE Ventilator-associated event surveillance was introduced in the National Healthcare Safety Network in 2013, replacing surveillance for ventilator-associated pneumonia in adult inpatient locations. We determined incidence rates and characteristics of ventilator-associated events reported to the National Healthcare Safety Network. DESIGN, SETTING, AND PATIENTS We analyzed data reported...

Background—The Fontan procedure is a successful palliation for children with single-ventricle physiology; however, many will eventually require heart transplantation. The purpose of this study was to determine risk factors for death awaiting transplantation and to examine results after transplantation in Fontan patients. Methods and Results—A retrospective, multi-institutional review was perfor...

OBJECTIVE Variability in the breathing pattern of patients with cancer during radiotherapy requires mitigation, including enlargement of the planned treatment field, treatment gating and breathing guidance interventions. Here, we provide the first demonstration of how easy it is to mechanically ventilate patients with breast cancer while fully conscious and without sedation, and we quantify the...

background in some hospitals, urinalysis is done routinely for all patients scheduled for cardiac surgery. occasionally pyuria or bacteria is reported in the microscopic urinalysis of these patients that are clinically asymptomatic for urinary tract infections. objectives we were seeking answer to this question: is the presence of a different number of bacteria in preoperative microscopic urina...

patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

The home ventilator market has grown in size and complexity. The aim of this study was to determine if common home ventilators are user-friendly for trained intensive care unit (ICU) physicians. Eleven ventilator models were tested by 13 ICU physicians without practical experience in home mechanical ventilation. Six tests were defined (start-up, unlocking, mode and setting recognition, mode cha...
