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...

Pressure support ventilation (PSV) is a commonly used mode. It is patient-triggered, pressure-limited, and (normally) flow-cycled. Triggering difficulty occurring during PSV is usually due to intrinsic positive end-expiratory pressure. The airway pressure generated at the initiation of inhalation is determined by the pressure support setting and the pressure rise time (pressurization rate) sett...

BACKGROUND Strategies are needed to help prevent ventilator-associated pneumonia. OBJECTIVE To develop a ventilator bundle and care practices for nurses in critical care units to reduce the rate of ventilator-associated pneumonia. METHOD The ventilator bundle developed by the Institute for Healthcare Improvement was expanded to include protocols for mouth care and hand washing, head-of-bed ...

Many ventilators measure expired tidal volume (VT) without compensation either for the compliance of the ventilator circuit or for variations in the circuit setup. We hypothesized that the exhaled VT measured with a conventional ventilator at the expiratory valve would differ significantly from the exhaled VT measured with a pneumotachometer placed at the endotracheal tube. To investigate this ...

Since 2001, financial support has been provided for all patients with neuromuscular disease (NMD) who require ventilatory support due to the paralysis of respiratory muscles in Korea. The purpose of this study was to identify ventilator usage status and appropriateness in these patients. We included 992 subjects with rare and incurable NMD registered for ventilator rental fee support. From 21 F...

Deaths and injuries related to accidental ventilator disconnection occur in complex ways. A death related to accidental ventilator disconnection is presented from a subacute ventilator facility, and corrective action is discussed. Single-limb ventilators are now equipped with a flow-bypass coupling that prevents patient-side occlusion during disconnect and therefore prevents low-pressure alarm ...
