Ventilation and ventilators — an update
Journal of Medical Engineering & Technology, 1988In the five years which have passed since the previous review, the literature has been concerned more with the ways in which ventilators may be applied to patients and the effects of differing patterns of ventilation than with the design philosophy of the ventilators themselves. This account should be read in conjunction with that of 1982 [1].

Partial Liquid Ventilation Ventilates Better than Gas Ventilation
American Journal of Respiratory and Critical Care Medicine, 2000Abstract Partial liquid ventilation (PLV) improves oxygenation in several models of lung injury. However, PLV has only been compared with conventional gas ventilation (GV) with low PEEP. Both PLV and GV can markedly improve oxygenation when PEEP is set above the lower corner pressure (Plc) on the inspiratory pressure-volume (P-V ...

Ventilator modifications for intermittent mandatory ventilation
Critical Care Medicine, 1979A Loosko MK2 ventilator has been modified to provide IMV in newborns. IMV rate can be varied from 3-60/min. The minimum inspiration period can be theoretically as low as 0.1 sec. This modification in neonatal mechanical ventilation has been shown to be economically feasible.

Differential lung ventilation with a modified ventilator
Critical Care Medicine, 1981To achieve synchronized differential pulmonary ventilation, an Ohio 560 ventilator was modified through separation of the outputs of the deep breath bellows and the tidal volume bellows and providing independent volume, flow rate, PEEP, oxygen-humidification, and alarm systems.

Considerable clinical experience confirms that oxygenation can be improved in many patients with ARDS by employing prone ventilation. The improvement occurs because, in the prone position, the lung fits into the thorax such that lung distention is more uniform and compressive forces extant in the supine position, which serve to cause dorsal airspace ...

Best Practice & Research Clinical Anaesthesiology, 2010
Preventing ventilation-induced lung injury and bronchopulmonary dysplasia is an important goal in the care of ventilated neonates. Recently, there have been tremendous efforts to improve ventilation strategies, which aim at ventilating with a 'protective' and 'open-lung' strategy.

Ventilator waveforms are graphic representations of changes in pressure, flow, and volume within a ventilator circuit. The changes in these parameters over time may be displayed individually (scalars) or plotted one against another (pressure-volume and flow-volume loops).

Ventilating the debate: elective ventilation revisited
Journal of Medical Ethics, 2013This issue of the Journal of Medical Ethics features a special symposium on ‘elective ventilation’ (EV). EV (also known as ‘non-therapeutic ventilation’ (box 1)) was originally described in the 1990s by doctors working in Exeter in the UK.1 At that time there was concern about the large shortfall in organs for transplantation.

The Ventilator Circuit and Ventilator-Associated Pneumonia
Respiratory Care, 2005Historically, the relationship between the ventilator circuit and pulmonary infection was accepted as fact, without any scientific evidence. Hence the term, "ventilator"-associated pneumonia. Recent evidence, however, has demonstrated that the major sources of pneumonia in the ventilated patient are colonization of the gastrointestinal tract, with ...

Non-invasive ventilation (NIV) refers to the delivery of positive pressure to the airways and lungs in the absence of an intratracheal tube or an extra-glottic device. The term “NIV” includes both continuous positive airway pressure (CPAP) and any form of non-invasive inspiratory positive pressure ventilation (NPPV), in which an expiratory positive ...
