Mechanical ventilators and ventilator testers
2004In the human organism, the respiratory function is involuntary and essential to life. At times, however, as in surgical operations using general anesthesia or as a result of respiratory insufficiency, the patient needs help breathing. In the first case, the general anesthesia completely stops the thoracic muscles and a mechanical ventilator is needed ...

Partial Liquid Ventilation Ventilates Better than Gas Ventilation
American Journal of Respiratory and Critical Care Medicine, 2000Partial 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) curve of the total respiratory ...

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).

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.

A Review of Ventilation and the Quality of Ventilation Air
Indoor Air, 2000Ventilation is pivotal in terms of securing optimum indoor air quality. In addition, it also has a major impact on energy use in buildings. It is important, therefore, that the role and impact of ventilation is fully understood and that ventilation is employed efficiently.

Local ventilation is often a very important part of the ventilation system. It is used to diminish or, preferably, to prevent exposure to contaminants (including heat). This includes protection of persons or products from hazardous or nuisance contaminants. Efficient operation of a local ventilation system must account for exhaust flow field as well as

ICU Ventilators Versus BiPAP Ventilators in Noninvasive Ventilation
2016In contrast to the closed-circuit ventilation of invasive ventilation, noninvasive ventilation (NIV) is an open-circuit ventilation where leaks are inherent and, paradoxically, essential to its success. The success of NIV, whether in the acute setting, weaning, or long-term therapy is dependent on all three aspects for its use, appropriate patient ...

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.

Clinics in Chest Medicine, 2000
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 ...
