Mechanical ventilation

1. The use of fans and intake and exhaust vents to mechanically distribute ventilation and other conditioned air.
2. A forced ventilation method that circulates the air, removes odors, and controls humidity within the building. It is often used in wet areas such as food preparation rooms and bathrooms to control odor. Ceiling and window fans or portable ventilation devices are used to circulate the air within the space. They cannot be used for air replacement unless a clear indoor/outdoor circulation pattern is established. See also: Ventilation systems

mechanical ventilation

The process of supplying outdoor air to a building or removing air from it by mechanical means, e.g., with fans; the air which is supplied may or may not be heated, cooled, or air-conditioned.

The reason for failed treatment is that, the consumption of surface active material results in pulmonary collapse and the release of inflammatory mediators, barotrauma and shearing injury caused by mechanical ventilation aggregate lung injury, the release of endogenous NO of those patients is reduced, and moreover pulmonary arteriospasm can induce pulmonary hypertension; therefore, mechanical ventilation alone is lowly effective for some newborns with severe respiratory failure.
This paper will provide a much needed resource to guide policies that will ensure that our patients' ventilators will be initiated and managed by those individuals that have proven competency on safe initiation and management of mechanical ventilation.
Failure or intolerance at 15 minutes of SBT was defined according to one of the following criteria: peripheral oxygen saturation (SpO2) measured by pulse oximetry of less than 90% (80% in chronic respiratory failure), respiratory rate (f) of greater than 35 respirations per minute, heart rate (HR) of greater than 140 or less than 50 beats per minute (bpm) or increase or decrease of greater than 20% in previous mechanical ventilation, and systolic arterial blood pressure of greater than 180 mm Hg or less than 70 mm Hg or increase or decrease of greater than 20% in previous mechanical ventilation.
The form included demographic data (age, sex, weight, height), clinical data (diagnosis prior to ICU admission, indications for mechanical ventilation, SOFA score, APACHE II score, SAPS II score, Glasgow Coma Score, vital signs, laboratory and imaging data) and therapeutic variables (vasoactive drugs, antibiotics, immunosuppressant's and bronchodilators) commonly used at the ICU.
