conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

Learning Objectives: 1. Define ventilator associated pneumonia and identify its related complications 2. Discuss current preventive measures for ventilator associated pneumonia 3. Describe the various mechanisms of probiotics 4. Evaluate the current literature for the use of probiotics for the prevention of ventilator associated pneumonia

Improving Intensive Care Unit (ICU) outcomes by reducing ventilator associated complications and ventilator days may warrant re-engineering the weaning process.1 Alternative methods which assist clinicians in organizing and implementing accurate weaning processes may shorten the duration of ventilator dependence and positively impact ICU outcomes.2 Knowledge based weaning (KBW) provides an alte...

Ventilator-associated pneumonia (VAP) is a complication of ventilator care that produces excess, avoidable resource use and treatment costs. Control of VAP is an important aspect of quality of care improvement for long-term care hospitals (LTCHs) since they provide post-acute ventilator care for many Medicare beneficiaries. Data for Medicare patients discharged from LTCHs during CY 2004 who rec...

Potentially harmful effects of positive pressure mechanical ventilation have been recognized since its inception in the 1950s. Since then, the risk factors for and mechanisms of ventilator-induced lung injury (VILI) have been further characterized. Publication of the ARDSnet tidal volume trial in 2000 demonstrated that a ventilator strategy limiting tidal volumes and plateau pressure in patient...

Mechanical ventilation (MV) is a life supporting treatment that, unfortunately, can be associated with several complications such as ventilator-induced lung injury, ventilator associated pneumonia or ventilation induced diaphragm dysfunction (VIDD)[1]. Clinicians generally try to provide assisted/supported ventilation instead of fully controlled ventilation in critically ill patients [2]. This ...

The ventilator inhales fresh air from outside into the inside cabin of a vehicle and exhales hot air to the outside. On a sunny day, solar energy can be used to run the ventilator, and to charge the battery simultaneously. During a cloudy day, the ventilator can be driven by the battery. In this paper, heat transfer and energy balance inside the car were investigated. Moreover power consumption...

This paper focused on the design of ventilator algorithm and Hardware-in-Loop Simulation on the LabVIEW based ventilator control system. The ventilation algorithm had a double-layer structure. The upper layer was ventilation mode algorithm, while the lower layer was PID control algorithm. They worked at different periods. The lower layer served the upper layer and to achieve the constant voltag...

Recent publications have suggested that in infants receiving artificial ventilatory support a particular pattern of interaction between spontaneous breaths and ventilator inflations (active expiration against each ventilator inflation) may be important in the production of pneumothoraces. We have looked at patterns of interaction from 47 preterm infants studied on 51 occasions. We found that ac...

Manual transcription inaccuracies have been reported to be a frequent occurrence in clinical practice, which has been confirmed in my institution. I explored alternative methods of obtaining data directly from the Puritan Bennett ventilator. The aim of this project was to record all of the ventilator settings and monitored data with wireless technology. I evaluated 2 data-capture methods: on-de...
